Snooping sister 3 During the next week Nilla had Cathy to suck her pussy at every chance she got and she fiddled with Cathys pussy when they sat downstairs watching tv. Nilla knew that her mum listened and got more bold after each time she had Cathy perform sex on her while their mum listened outside. Cathy was still in the dark that her mum knew about what she and Nilla did so sneaking away to have sex gave her an extra thrill. Cathy munched pussy at least three times a day and most of the times Nilla wanted more than one orgasm. Sometime Nilla came in to Cathys room after bedtime and just straddled the young girls head and let her sister lick her to orgasm. Nilla became more obvious to show her mother when she where going to have her sister to go down on her and all the time Pat stood by the door and listened. Some days when Pat got home and walked up to see her daughters all activity was finished by she could smell the sex all over the upper floor. Nilla just grinned but Cathy believing her mother did not know tried to look innocent but her blushing face told another story. Pat decided she needed to talk to Nilla and get this to stop but she did not wanna do it when Cathy was home. She had to wait another half week before Cathy went away friday to her best friend Amy for a sleepover and that gave Pat the opportunity to talk to Nilla. As they sat down to eat dinner Pat cleared her voice and said. -Nilla, you have to stop this you are doing with Cathy. Nilla just grinned. -And what is that? Irritated Pat said. -You know very well what I mean. But Nilla just grinned her annoying smile and looked totally blank at her mother. -You cant keep on forcing your sister to have sex with you. Nilla put her elbows on the table and put her head in the hands because she knew it drove her mother crazy. -It is not like I am forcing her to do anything, she is just a horny slut that loves to lick pussy. Pat got mad and shouted. -Dont call your sister slut and take your elbows off the table. With a mild voice Nilla answered. -Why are you screaming mother, I am not deaf. Nilla took her arms from the table and slumped back into her chair while she continued to talk. -I remember an night more than two years ago when two grown up forced me to have sex. -And this was really forcing a 14 year old to do something she did not wanna do. -It is not like this with the horny slut to sisters that comes begging for a chance to suck my juicy pussy. -It was two persons manhandling me and my younger cousin Winnie to performing sexacts all weekend. -I dont say that I did not like it in the end but there was not any discussion if we wanted to participate. -So dont go all high and mighty on me. Pat sat stunned at her daughters accusing words and got up from the table and threw her plate in the sink. She turned to get out of the kitchen but Nilla had moved out of her chair and stood in her mothers way. -Out of my way. -No you dont escape again, this time you will stay and talk with me. Fuming of anger Pat tried to force her way past her daughter but Nilla stood her ground and pushed her mum back. Pat slapped Nilla hard in the face and screamed. -MOVE. Nilla did not budge. -Did you enjoy fucking your daughter two years ago? Pat attacked Nilla with fury and was on her way to get past her but tripped on her daughters left foot and fell. Nilla threw her mother backwards into the kitchen on her back and when her mum got up on her feets Nilla attacked and pushed Pat hard against the kitchen sink. They wrestled for a couple of minutes and none of them got the advantage of the other. But after five minutes of pulling, pushing and punching each other Nillas condition started to give her the upper hand. She was slowly wearing her mother down and she could feel the fighting spirit beginning to leave her mother. That gave Nilla extra strenghts and she pinned her mother to the sink. -Did you enjoy fucking your daughter two years ago? Nilla held her mother hard and said the words gasping in her right ear. -Now did you? Nillas body pushed and pushed at her mothers body and both female where sweating. Nilla hip and upper leg pushed hard on Pat pussy and Nilla pushed harder and faster. -Well, mummy whore, did you like fucking your daughter? -Tell me. Nilla hands slided in between their bodies and then roughly tried to rip her mothers blouse apart. -Tell me you fucking whore. This made Pat desperate to get away and she made an another attempt to fight her daughter off her but the only thing she managed to do was to drain her strenght even more. Nilla teased her mum. -Come on mum, fight me off. -Is this all you got? Nilla bit her mother on the jaw making her scream of pain and Pat tried to struggle out the grip Nilla had but to no avail. All the time Nilla push her hip hard at her mothers pussy and kept on tearing the blouse apart. Nilla could feel her advantage in strenght increasing and knew all her hard training was paying off. Finally the blouse opened up and Nilla embraced her mother putting both hands on her back. Kissing the side of Pats neck while mumbling all the time. -Did you enjoy fucking your daughter. -Tell me. Nilla kept on kissing up to the ear and sucked the earlobe in her mouth. She felt her mother shiver and Nilla quickly shifted side to kiss other side of Pats neck at the same time snapping the bra up. -Tell me you fucking whore, did you enjoy fucking your daughter two years ago. -I am so sorry. -Shut up fucking cunt, shut the fuck up. In rage Nilla lifted one of her hands at the back and planned to grip her mothers hair to pull it back but missed and pulled the blouse at its collar instead. This pinned her mothers arms and restrained her. Nilla realised her luck and took her free hand and viciously lifted the bra over her mother head and over to her back. She gathered the bra in the hand that held the blousecollar and reached with her free hand for the dishbrush. She got the brush and wedged it between her mums back and clothes and twisted the brush around to make a knot. Everything had gone so fast that Pat had not realised what happened but now she tried to fight back but Nilla gave her a hard punch in the stomach. Pat legs buckled and when she instinctively put her arms on the bench to hold herself up it gave Nilla the chance to turn the brush round two times and then again twist it so it lodged between Pats shoulderblades. Pats arms was thightly secured behind her back and she could only move her arms one direction and that was further back. When she tried that the dishbrush turned a little and got stuck with the end of the handle pushed at her back. -Thank you mum for presenting yourself to me in this way. -Proudly showing your tits for me. Nilla grabbed a roll of scotch tape and used it to secure the dishbrush and clothes. She even tape her mothers hand together behind her back. -Nilla returned to her kissing and mumbling. -Tell me mummy whore, did you like fucking your daughter? -Do it, tell me. -You hurt me when you just tried to ignore what happend and never fucked me again. -But your perverted side could not be hidden totally so instead you began listening to when I masturbated. -And I know that you have been watching me and the slut going at it. - Thats why I left the door open a little, just to give pervy Pat a show. -But auntie Gina did not stop fucking me. -Noo, she gave me an education in how to dominate and force somebody to do sexual acts. -Slutty Winnie has been our fuckpet these two years and she really gets wild when we play with her. -My whore sister saw some pictures that I had printed out when she snooped around and was pleasuring herself when I came home. -So I fucked the whore and she loved it. All the time speaking Nilla kissed, caressed and pushed her mother and slowly lighting a fire inside her body. Pat was surprised that Gina had doubleplayed her because she had promised Pat she never done anything more to Nilla. Pat grunted. -Dont call your sister whore. Nilla pulled the zipper on her mothers skirt down as she replied. -No your right. -The only whore in this house is you, sister is just an insatiable horny bitch that I going to teach how to be my sexslave. The skirt fell to the floor as Nilla continued talking. -This last week she has sucked my pussy at least three times a day, often more. -I get up in the middle of the night and straddle the sluts head and force her to lick me. -Sometimes she has to lick me to two orgasms before I leave but she never complain. -She is such an obedient pet. Pat could not believe that this happened under her own roof and that she never knew about it to the full extent. Nilla kissing and fondling began to take it toll on Pat and her hip met Nillas as she pushed into her pussy. -Is mummy whore likeing this? Nilla said in an taunting voice. -I can get slut pet to lick mummys pussy too. -All you have to do is to ask for it. Nilla began pushing harder at her mothers pussy and she bent her head to suck on a nipple. Nilla sucked hard on the nipple and then released it with a plopping sound. -Just say slut pet need to suck my pussy and I will have her do it. Nilla gripped both nipples and pulled them out making Pat grunt of pain. Then Nilla pushed her head between her mothers tits and shook it while making a blubbering sound. Nillas face came up grinning. -Even though I was intoxicated two years ago I still remember those big tits swaying above my head as you held down my arms. -So I have always since that wanting to do that. -I even remember you slapping my face with your tits while giggling as Gina pumped away at my cunt. Then with an evil grin Nilla gripped Pat left breast and squeezed hard. As Pat screamed Nilla took one step back and pulled off her t-shirt then pushed down her shorts and panties. Nilla kicked the clothes to the side and then pulled her mothers panties down to her knees. Nilla stepped closer to her mother, used one foot to push her mothers panties the rest way down and embraced her again. This time it was skin against skin when Nilla pushed her hips at Pats pussy and Nilla grinded slowly by moving her hip sideways. -Now tell me did you love fucking your daughter two years ago? Nilla was back to kissing Pats neck and giving her mother small bites on the side of her jaw while increasing pressure on her hip. Her mother was really wet so her hip slided easy over the slick mound. -Tell me you loved fucking your daughter. -Hmm did you not do that? Pat groaned as Nillas hipbone wiggled over her pussy. -Yeah, mummy whore likes it. Nilla grinded harder and this time Pat moaned with open mouth her arousal. -Mummy whore is going to climax but not before mummy whore tells her mistress how she felt fucking her daughter two years ago. -Tell me, mummy whore, how did it feel? Without thinking out it Pat lifted her left foot out of her paties so she could spread her legs more. Nilla felt the movement and looked down and saw what happened. -Thats right get those lovely legs wider apart, mummy whore. Pat suddenly realised what she done and tried to close her legs but Nillas thigh was firmly placed between her mothers legs. -Nono, dont back down now, mummy whore. Nillas fingers worked on her mothers nipples as she pumped harder against her. -Tell me so that I can give you an orgasm. Nilla had been teasing and manipulating her mother for almost an hour and Pats resistance crumbled. She opened her legs wider and grunted out. -Fuck me. -Not yet, mummy whore, not before you tell me how you liked fucking your daughter two years ago. -So tell me the secrets. Pat grunted but gave up. -I loved fucking you. -I loved it so much that it scared the hell out of me. -Oh, mummy whore, you should had told me this long time before. -So much would have been different. -But now mummy whore is going to have nice good cums. Pat did not register that Nilla talked about more than one, she was just interested to get this off as quickly as possible. Nilla pushed and grinded at Pats pussy while kissing the side of her neck and pinching right nipple. Pat was so close that she saw stars but Nilla backed away little, just so much that Pat would not cum. -Soon I am going to fuck slut pets pussy for the first time and the you are going to be in the room watching. -I am going to tie her up and blindfold her and you are going to come into my room to watch. -Do you hear me mummy whore? -What are you going to do? Pat was desperate to get sexual relief so she agreed. -I going to go into your room and watch you fuck Cathy. -Oh no, not Cathy. -I am fucking slut pet, say it. Nillas constant prodding and caressing broke Pat down. -I am going to your room and watch you fuck slut pet. -Good mummy whore, now comes the reward. Nilla engulfed Pat in a tight embrace and grinded her upper leg at her mothers pussy really hard. -Oh god. With an explosion Pat climaxed and Nilla coaxed every bit of that orgasm out of Pat. -Uhhh fuck, aaarrgghh. At the first tendency that Pat was calming down Nilla speeded up her grinding and first orgasm passed over to second. An even more mindnubbing one for Pat who this time lost all her composure and screamed right out. -God dammit, aauugghh oouuhh aarrr. Nilla milked all of the orgasm out of Pat and then took one step back. She plunged two fingers from her right hand inside Pats pussy and jammed her thumb on the clit and began pumping in and out. Nilla put her left hand on her mothers throat and pushed her back over the kitchen sink. It was brutal the way Nilla fucked her mum with her fingers but never the less Pats third orgasm hit her. As Pat shook and shivered Nilla pushed her fingers as far up her mums cunt as she could and took a hard grip. Her thumb massaged the clit and the fingers massaged the inner walls of the pussy to stimulate Pats G-spot and Pat went from three to four orgasms. This time when Pat calmed down Nilla pulled out her fingers and stepped three steps back. Pats legs gave way and with a hard thud she fell down on her knees. -I might say that is perfect. Nilla pulled a kitchen chair in front of her mum and sat down. -Now mummy whore please her mistress. -I want at least two orgasms. -I think that fair since I just gave you four. Nilla lifted up her feets on the seat and spread wide. -Yummy for mummy. -Come and get it. Nilla guided her mother head with her hands and when she felt the first lick she almost orgasmed at once. Even if she did not cum directly it took only a minute before she climaxed. -Fuuuccck yeaah. Pat stopped but Nilla would not have anything with that so she slapped her mothers head hard when she stopped licking. -Go on, I want more. And Pat licked her daughters pussy for another thirty minutes bringing Nilla to two more orgasms. -Oh god, this has been great. -But all good has an end. With that Nilla stood up, turned the dishbrush loose and took a knife to cut the tape. Finished she left the kitchen without a word.
