MY SEXY SISTER-IN-LAW James was at home preparing to watch a movie and pondering how his wife's business trip was going and whether at 8pm she was still stuck in a long evening meal with her boss and other work colleagues or if she'd already retired to her room in the hotel. Just as he was selecting a movie from the shelf he thought he heard a knock at the door, walking to the dvd player movie in hand he was sure he heard a knock at the door, who would that be he wondered? As he opened the door he was very surprised to see his sister-in-law standing there and could do little more than mumble a surprised, "Hello?" "Aren't you going to invite me in?", she asked. "Umm, sure...", he replies, opening the door and motioning her in towards the lounge. "So, what were you up to?", she askes. Bemused, he replies, "Ahh, just about to watch a movie. You know Steph is away, don't you? She's not here." "Yes, I do." "Oh, so, um you just came to see me?", he questions. "Steph didn't tell you then?" "No, um tell me what?", he answers getting even more confused. "Well, when she's away, on business, she worries about you. Worries you're not taking care of yourself so she asked me to look in on you from time to time to make sure you're ok, you know, looking after yourself. So, here I am.", she smiles at him. "Yes, here you are", he says, still confused about this visit as he motions her through the door towards the lounge room. His sister-in-law has never visited before when his wife wasn't home, it was very strange. "So what we're you up to?", She asks as she removes her coat and sits on the 3 seater. "Just about to watch a movie.", James answers, just as he thinks to himself that the movie he had picked out wasn't really suitable for mixed company, "Did you want to pick one?" "Haven't you got one out already?", she smiles looking towards the DVD case sitting ready next to the TV. "Uh, well, yeah but probably not something you'd like. Let's choose something else.", he responds evasively. "Really?", she responds arching her eyebrows, "what is it?" "Uumm, well, not something I'd usually watch with my sister-in-law." "Now I am interested, show me.", she demands. He hands over the DVD case for his sister-in-law to look at. He watches the knowing smile on her face as she sees the cover, "The Awakening of Gabriella" produced by Playboy studios with a picture of the main actress showing her ample breasts on the front cover. "Not something I'd usually watch, you're right, but in this case I think I'll make an exception.", she states, "Besides, I don't want to ruin your night, came to give you some company and make sure your ok not make you watch something you didn't want to.", she says with a smile. Putting the DVD in James settles on the couch and picks up the remote just as his sister-in-law settles down beside him with a grin, "this should be fun.", she grins. Not sure how to take that comment James starts the movie and about 15 minutes in he's caught off guard by a sudden comment from his sister-in-law, "She's got nice tits hasn't she? Think they're real?" "What??? Oh, ahh, yeah they seem to be, don't they?", he answers. As the movie goes on he is glad he's sitting down because he's more and more aware of the hardening erection in his pants, thinking how embarrassing it would be to have to stand up with that while his sister-in-law is there, which is why when she suggests he get them some hot drinks as it's a cold night. Standing up to head into the kitchen he thinks he notices a mischievous grin from her as she glances towards his bulging groin. It's only while standing in the kitchen, making them both fresh coffee's, looking back into the lounge that he notices how sexy his sister-in-law looks tonight. She might have said it was a cold night but she's taken her jacket off and he's only just realised she's not wearing a bra under her top. He almost over-fills one of the coffee cups as he's enjoying looking at her breasts straining the material of her blouse and the way the chill in the air is causing her nipples to harden and strain the thin material. Taking the coffee's back to the lounge he realises, he doesn't think he's ever seen her dress quite like that. If anything oogling his sister-in-law's breasts has only made his cock that much harder. Sitting down James gets back into the movie and is enjoying the hot coffee and his hot sister-in-law sitting right next to him on the couch, perfect company for this movie. He's seen it before, but never with anyone other than his wife. "Watched this with Steph have you?", she asks him suddenly. "Uh, yeah, why", he answers. "Oh, just wondered if you ever tried any of the things from the movie out, like that for example?", she asks archly while gesturing to towards the screen. James looks at the image on the screen as the male actor in the movie thrusts his cock into the ass of the actress playing the female lead in the movie, as she groans in pleasure and pain in time with his thrusts. "No, not like that.", he says quickly. "But, some of them then?" "Well some, yeah." "Sorry, you seem embarrassed." "Not really, well a little, don't really make a habit of talking about our sex life with anyone. You understand?" "Sure.", she responds, "but you know we're sisters right?" "Yeah?" "So, sisters share everything, so you think she doesn't tell me everything?" "Oh.... so she tells you everything then..???", he asks, suddenly wondering just how far `everything' goes. "Well, maybe not everything, but a lot.", she smiles at him with a not so subtle glance down at his groin. A little embarrassed by the way the conversation is going James goes to sit up to take his empty mug back to the kitchen and somehow bumps his sister-in-law and causes her to spill the remants of her coffee all over herself. Without thinking he quickly grabs the roll of paper towel from the kitchen and rushes back to dry her off. Only as he is almost finished drying her off does he realise he's had his hands all over his sister-in-laws ample breasts, and have even been almost massaging them as he tried to dry her off. As he comes to this realisation his eyes lift to hers and he can see the amusement there as she was waiting for him to realise just the situation they were in, "Sorry", he says quickly. "Don't say sorry.", she smiles at him, "thanks for drying me off. I think I still need a clean top though, this one might stain from the coffee being white, so I'd love to soak it?" Thinking about his petite size 10 wife he doesn't think her curvy size 14 sister would fit into any of her tops, "You might need to wear one of my t-shirts, is that ok?", he asks. "Sure, can you bring me one in the laundry?", she asks. James walks into the laundry and see's his sister in law throw her top into the trough to soak and only as she turns to him to grab the t-shirt does he realise, she's now not wearing anything on the top half. He's pleasantly greeted by the beautiful site of her ample 14D breasts, complete with thrusting nipples staring at him. Speechless, he just stands there holding the t-shirt, before hearing, "You might be enjoying the show but it's actually a little chilly here." With that, he realises he's obviously been staring and can feel the heat rise in his face. Embarrassed he holds the shirt out as he turns to avert his eyes and says, "Sorry! I was, surprised to see you." "Really? But you knew I was here didn't you? How were you surprised?", she asks demurely. "I, I think you know.", he stammers. "Oh, so you were surprised to see my bare breasts staring you in the face, is that it?", she smiles, pushing her shoulders back at the same time to emphasise them even more. James had never seen this side of his sister-in-law before, he was amazed. She'd always seemed so reserved and had certainly never flirted with him before, as he was acutely aware she was doing so now. "Better give me that T-shirt of yours,", she says taking it from his hands. James enjoys watching her lift her arms up to get them into his T-shirt and the way that drew her breasts up, and bring her nipples tantalisingly close to his eye level. The throbbing in his groin was certainly encouraging him, almost beckoning him to step forward and wrap his lips around those hard nipples, standing proudly on his sister-in-law's breasts. His thoughts are interrupted by the T-shirt sliding down over his sister-in-law's breasts, just in time for him to notice that the T-shirt hardly looks like his when she's wearing it. "Lucky I didn't spill it in my lap,", she grins as he notices the t-shirt hangs down on her to mid thigh. "Yeah", he answers distractedly, "guess we should get back to the movie, if you want to?" "Sure", she replies. As the end of the movie approaches he notices she's been moving around a lot, "are you comfortable?", he asks. "Yeah, it's not that, think I strained something in my back when I spilt that coffee," she says stretching her back out, "Say, Steph is always telling me you give great massages, think you could oblige." James certainly wants to oblige. After watching the playboy movie, his earlier inadvertent and unexpected feel of his sister-in-law's breasts, and the up close viewing later in the laundry he couldn't wait for her to leave so he could relieve himself with thoughts of her breasts and how they'd move as he rammed his cock into her. The thought of give her a massage was almost too much. James hadn't given anyone other than his wife a massage since getting married some years ago. All that was going through his mind as his mouth voiced the words, "Sure, I'd be glad to." "Where do you usually give Steph her massages?", she asks. "on the best, no where else really comfortable, is that ok?" "Sure", she says, heading towards the master bedroom. "How do you want me?", she asks as she sits on the bed. Screaming as my cock rams into you and my fingers are squeezing your nipples James thinks as he says, "Uh, Steph normally lays on her chest with her arms out to her side." "Ok", she replies lying face down on the bed. James starts trying to massage her back standing beside the bed, but it's hardly as effective as his usual position straddling his wife where he can easily reach the length of her back. Trying to work her back muscles while she's still wearing the t-shirt doesn't help. "Don't mean to complain, but this doesn't feel like the massages Steph has raved to me about." "Uh, that's probably because this isn't how I do her massages." "So how do you do them." "Well she doesn't usually have clothes on for a start", James says without thinking. "No problem.", she says, as she immediately slides the t-shirt over her head and then lifts her middle section up to undo the button on her jeans before she slides them down over her buttocks, which are now not covered at all by the G-string she's wearing, and down off her feet. With one hand she snaps the clasp on her bra and releases it, "better?" "Uh, yeah. But one more thing", James answers. "What's that?" "Well usually I sit on the bed, behind her and massage from there, where I can reach better." "So let's do that, my back is sore." James quickly slips some soft tracksuit pants on so his jeans don't chafe her and climbs up straddling her thighs and enjoying looking down over the generous mound of her ass where her cheeks are clearly defined by the thin cord of her g-string and down across the arch of her back to her shoulders where he can see her breasts just bulging out the side of her torso now that they're not restrained by her brassiere. Rubbing his hands together to warm them and the massage oil up he leans forward and starting at top of her hip bones, he massages his hands along either side of her spine to the top of her back and then draws them back down. Repeating that motion he hears a satisfied sigh escape her lips. Working down one side James uses his hands to massage along the line of her ribs and gently caresses the side of her breast as he works his way down her back. As he leans forward again to massage the top of her back he can feel his hard cock naturally rest between her buttocks. As he reaches the top of her back, he's surprised by the pressure he feels from his sister-in-law pushing her ass back against his cock. The pressure feels amazing and the thought that a thin sting of cotton making up her g-string and another piece of cotton from his track-suit pants is the only thing stopping his cock from making skin to skin contact with her ass. Rubbing his hands down her side she takes a big breath as his hands reach her breasts and before he realises, his hands have slipped around the side of her breasts and caressed her nipples, which seems to electrify his sister-in-law, as she arches her back and lifts herself even more so he can reach better. Before he realises it, he's leaning over his sister-in-law, almost dry humping her through his track-suit and squeezing her nipples on her breasts as she moans in pleasure and suddenly demands, "so you going to fuck me or what!" "What?", he says surprised. "You heard me, you going to fuck me or what?", she demands again, "Steph is always telling me how great your cock is. Time for me to find out first hand." "Look, don't think I don't want to, but, I ahm, don't think I should, sorry.", he says "Really, you perv on my tits, you rub them, practically dry hump my ass, I'm practically naked on this bed here and all you can say is, you don't think you should? Not good enough." "Sorry, I am, I shouldn't have done what I already have, I don't know what I was thinking. But I can't." "Right. You can't. Let me tell you how this is going to go. Either you get that hard cock that I can feel rubbing against me out and fuck me, or I tell Steph I came over to keep you company and you ripped my shirt off and copped a feel of my tits. She's always telling me how you're so into tits, bet you've been perving at mine too so she won't be surprised. What's it going to be?" Realising the predicament he's in, James decides there's nothing for it. But if he has to he's going to give her something to remember. James quickly slips his pants and shirt off and lays down on his sister-in-law and and then almost viciously pulls her g-string to the side and without any preamble rams his cock into his sister-in-law's pussy, which to his surprise is wet, moist and ready for him. In fact, she's already grinding her hips back against him. Pulling some lube from the drawer beside the bed he quickly lubes up a finger and plunges it into his sister-in-law's ass as his cock still works it's way in and out of her pussy. She clearly enjoys it as she moans in pleasure in response. "You like that?", James asks. "Oohhh, yeahh.", she moans, "I like that, like it like that.." James keeps working his cock in his sister-in-law's tight pussy as his finger works in and out of her ass. She's moaning more and more and he can feel her pussy clamping down on his cock. He works himself inside her, almost trying to impale her with his cock. The harder he pushes the more she likes it. She's moaning as he times the thrusts of his cock in her pussy with his finger in her tight ass, clearly enjoying the sensation. Not wanting this to be over too soon he suddenly stops, and pulls himself from her pussy and is rewarded with a sudden exclamation of disgust from his unsatisfied sister-in-law. Standing beside the bed he rolls her over onto her back and quickly rips off the remains of her g-string to reveal the mound of her pussy with a neatly trimmed crown of shaven hair above it. Given the bikini's she wears in summer it's what James expected. While admiring the view, almost without thinking he lifts her loose bra from her body exposing her luscious breasts to full view. "Enjoying the view", she asks wryly, "At least I can see that cock that all the fuss has been about. No wonder my sister talks about it so much." "At least I finally get a decent view of those tits you've been flaunting at me the last few years, walking around in those little bikini's and shirts cut so low they almost may as well not be there.", he riposte's. "Touche." James leans over her and grabs both her arms, pushing them back beside her head on the bed, and enjoys the way it lifts her breasts, making the nipples all the more prominent, almost begging for his mouth to caress them. She opens her legs, inviting him in and wraps them forcefully around his hips as he enters her once again. Expecting the sudden intake of her breath as he does, James is ready and quickly releases one of her arms to free his hand to grab her taunting nipple firmly, twisting just as he pushes as deep into her as he can. "Yesss", she moans in response. "Fuck me, fuck me like that, squeeze my nipples hard!!!" Happy to oblige James does just that. Rams himself into her like a jack hammer, enjoying the sensation as the head of his cock hits her cervix stretching her slightly, while he watches her delicious breasts move in front of him. Using one hand to hold her wrists above her head and the other to taunt her nipples, first one then the other she moans as she orgasm's from his stimulation. "You enjoy that?", he asks with a smile. "Yesss.", she replies dreamily. "Ready for more?" "Yeah... why not..", she answers. "Great, cos I'm not finished yet." While she's still enjoying the feeling of her orgasm and her body is completely relaxed James carefully lifts her legs up, holds them there with his left arm to expose her moist pussy lips and tight anus. Rubbing a little lube on his finger he begins rubbing back and forth across her perineum, starting around her tight ass he rubs around the outside before applying a little pressure but not yet penetrating her. Then he moves his finger up to her still moist pussy to rub along her slit before gently hitting her clit. Working himself into a pattern and generating a satisfying purr from her he begins to focus more on her ass. Begins to penetrate her tight back passage, although given her relaxed state, it's not quite as tight as it was earlier. Perfect he thinks. She's clearly enjoying the sensation of his well lubricated finger working into her ass as she becomes more aroused and is pushing back, encouraging him to push further into her. He can feel her loosening up even more as he continues. Almost ready he thinks to himself. James rubs a little lube on his hard cock that's still nice and wet from her pussy and presses the head of his cock against her tight, well lubricated passage. "Nnnoooo!", she suddenly gasps, "not there!!!" James figures it's payback time, if she's going to `make' him fuck her he's going to get his own back a little. Not that he didn't enjoy fucking her, not that he hadn't thought about it before. He leans down over her, putting even more pressure as the large head of his cock tries to force it's way into her. He almost feels a little pain from the pressure on his cock, just before it `pops' through into her accompanied by a satisfying scream from his sister-in-law. "Oohhhh, it hurts, please don't", she begs. "What's the matter, didn't Steph tell you I like to fuck her up the ass! You seem intent on taking her place tonight so it's your turn." "No she didn't tell me, she didn't!!!" That's probably because I've never successfully fucked her in the ass before, but no need to mention that figures James as he slowly pushes his cock fully inside her vice like ass causing another scream to emanate from his sister-in-law. Leaning forward over her, he whispers into her ear, "Look, just relax, babe, you started this, it's not like you didn't want it. I'll give you a second to get used to it, ok?" "Ok,", she sobs, barely holding back the tears. Clearly the first time she's had a cock, let alone one the size of James' in her ass. After a short couple of minutes, giving her time to relax a little, he slowly draws his cock back, squeezes a little more lube on it and rubs it in before leaning over her and holding each of her arms with his hands, he whispers to her, "Now babe, I'm going to fuck you in the ass. Try and enjoy it, I know I will." James begins pumping his cock in and out, violating her tight ass as she screams in response, begging him to stop. "Not yet babe.", he responds, "Not yet." As he continues he can feel the pressure build in his balls, getting ready to explode out of his cock. He notices the sounds from his sister-in-law have changed. She's beginning to moan, to enjoy it. He can feel her start to push back as he thrusts in, trying to get him that little bit deeper inside. James is rapidly approaching orgasm himself, his sister-in-law's ass is tighter than the tightest pussy he's ever been in. She's squeezing his cock so hard, he's building up even more pressure than normal before blowing his load. James leans forward over his sister-in-law and whispers in her ear, I'm going to cum in your ass. He increases his thrusts, pushing hard and faster in and out of her. She's almost screaming now, but with passion, not pain. Just as he starts to cum James slides his hands under his sister-in-law and latches on to her nipples with a hard grip and squeezes them harshly causing her to convulse under him as his hot cum empty's into his sister in law. Spent he collapses onto her and enjoys the sensation of his cum draining from his now softening cock into her tight ass. As he catches his breath, he lifts himself off her and rolls to the side, noticing the sharp hiss from her as his cock pulls out and her tortured ass can finally relax. As they both rest on the bed, James thinking what would his wife say if she knew? He had a fair idea, his marriage to his sexy wife would be over, she's never indicated she's interested in sharing him with her sister and while she never seemed to mind him perving on her sisters tits, perving is one thing and fucking her is something else entirely he's sure. Suddenly he realises she's no longer lying on the bed with him but has made her way into the ensuite and is getting the shower ready. Rolling over to admire the view he finds himself hardening up yet again. With a smile he grabs hold of his now erect penis and slowly pumps his hand up and down as he watches her step into the shower. Fortunately with the full width mirror he can watch her in the shower unbeknownst to her. He's definitely enjoying watching the water cascade off her long hair, down her neck and funnel between her generous breasts that not too long ago he was watching as she lay on the bed under him. James smiles as he watches her hands rub the soap down over her breasts and give her nipples a cheeky tweak before rubbing down over her stomach and continuing between her legs. Before he knows it she's stepping out of the shower and towelling herself down, and suddenly she turns to him with a cheeky grin, "enjoy the show? Your turn now." Guess she knew he was watching after all he thinks ruefully as he sits up off the bed and makes his way to the ensuite, to find she's thoughtfully left the shower going for him. Luxuriating in the steamy shower as he scrubs the soap through his hair he hears a sound and isn't sure what it was. Just as he's wondering he feels someone's arms wrap around his thighs and grasp his but cheeks, pulling him forward and slightly off balance as he feels warm soft lips envelop the head of his penis, causing it to harden instantly. James can tell straight away his sister-in-law definitely knows how to give head. She starts sucking on the end of his cock, rubbing her lips over it and gradually working him further and further into her mouth. Enjoying the sensation he's surprised when he suddenly feels her lips right at the base of his cock, she's taken him all the way inside her mouth and he can feel the head of his cock rubbing down the back of her throat. The vacuum she's building up in her mouth, sucking on his cock is definitely doing the trick. He can tell he'll be blowing his load very soon and hopes she'll take in the mouth, just like her sister. He's tried so far to restrain himself but can't help it, as he's about to cum he grabs the back of her head and pulls her face hard into his groin as he pumps load after load of cum deep into her throat. He only releases her head when he hears that she's almost choking, "Sorry", he says as the random thought of how he'd explain his sister-in-law naked and choking to death on cum in his ensuite shower while his wife's away runs through his mind. "That's ok", she smiles as she pumps the last of his cum from his cock and licks it off the end. Together they wash each other off and then dry off and get dressed. Sitting on the lounge enjoying a coffee afterwards James can't help but ask , "What now?" "What do you mean, what now?", she answers smiling coyly at him. "You know, where do we go from here, what do we tell Steph." "Tell her?? Are you kidding!!", she says, "Do you know what she'd do to you if she knew?" "Well, she's not going to be happy that's for sure, but I feel I should tell her" "Don't look at me to help you with that, I think it's a mistake." As she leaves, James is still wondering what, if anything to tell his wife Steph when she returns from her business trip in a few short days.
