Andrew looked out the bedroom window, watching Christina walk down the garden path and out through the front gate in a slinky black dress and stiletto heels. "I wonder what she's up to," he said, dropping the curtain and walking back over to the bed. Denise smiled up at him from the bed. "I thought she was looking a little hungry, so I told her to go play with Alex and Sarah. I'm sure they'll find it _very_ educational." Andrew grinned wickedly and climbed back into bed. "I'm sure they will," he said. "Now, what are _we_ going to do?" Denise stroked his erection and licked her lips. "I think this looks quite tasty," she said, and slid down the bed. * * * The doorbell rang. Alex folded his newspaper and left it on the arm of the sofa, then walked to the door and opened it. He blinked with surprise as he saw Christina standing there in a tight, slinky black dress - not at all her usual style. "Uh, hi Chrissi. Where have you been? I haven't seen you for ages." Christina smiled up at him, her eyes gleaming with scarlet light, and he felt his cock hardening in his jeans. He could have sworn her tits weren't that big last time he'd seen her. She licked her lips predatorily and reached up to caress his neck. "I've... I've been a little tied up," she said. "It's been very educational. Would you like me to show you?" He cleared his throat awkwardly. "Uh, I've got a... girlf... oh, fuck it." Sarah had never made him this horny with her clothes still on, so she could like it or lump it. Christina stepped into the house and pushed the door shut with her foot. "I know. I was thinking of a threesome," said Christina, unzipping Alex's jeans and slipping her hand inside. "You'd like that, wouldn't you, having two pretty girls to play with?" Alex swallowed hard as Christina caressed his cock. "Oh god yes," he groaned. She unbuckled his belt and tugged down his jeans and underpants, freeing his cock. "That's good. Let me taste you." She knelt down in front of him and took his cock into her mouth, caressing the shaft with her tongue. He ran his fingers through her hair with a groan of delight as she started to rock her head back and forth. Her fingers stroked lightly over his balls as they tightened, sending further shockwaves of pleasure through his body. Alex's fingers twisted in Christina's hair as she moved her head faster, taking him deeper into her mouth. "Ohhh.... Chrissi... make me come..." Her finger pressed against his anus, massaging the tight ring of muscle and working its way inside him. He whimpered in ecstasy as she massaged his prostate in time to the movements of her head, taking him past the point of no return. Alex almost collapsed on the spot when the orgasm hit. A sudden chill shot through his body as come spurted from his cock into Christina's mouth, and he felt oddly weak as she swallowed. "Wow," he whispered hoarsely. Christina rocked her head back off his cock and stood up. "Mmm. You taste good," she said, eyes gleaming scarlet. She pressed her lips to his, forcing her come-slicked tongue into his mouth. He smiled at the taste of his own come, and returned the kiss with great enthusiasm. * * * Sarah stomped grumpily up the garden path. She'd had a thoroughly awful day at work, and right now what she wanted was to curl up with a big mug of tea and rant at Alex. She pushed her key into the Yale lock and opened the front door, then stared in shock as she saw Alex lying naked on his back with Christina knelt naked astride his head, facing the door. Christina's eyes flashed scarlet, and Sarah felt her shock and grumpiness starting to melt away beneath that uncanny gaze. She supposed she could probably forgive Alex for wanting to fuck Christina. She quite fancied the idea herself, to be honest. Far too long since she'd eaten pussy. "Uh, hi Chrissi." Christina licked her lips and smiled at Sarah. "Join in or fuck off, but shut the door," she said. Sarah stepped into the house, pushing the door shut behind her, and kicked off her shoes. "That's better," said Christina. Sarah felt her sex twitching at Christina's sultry tone. She slipped off her jacket and started unbuttoning her blouse, feeling even more turned on by the frankly predatory look in Christina's eyes. As Sarah dropped her blouse to the floor and reached behind her back to unfasten her skirt, Christina darted forward and pressed her lips to Sarah's. Sarah whimpered as Christina's tongue forced its way into her mouth. She managed to undo her skirt, letting it fall to the floor, and immediately felt Christina's fingers diving inside her damp knickers. Sarah gave a muffled moan and started to return the kiss, slipping one hand down between Christina's legs. She was dimly aware of Alex moving around behind her, and then she felt him unclasping her bra with one hand and tugging her knickers down with the other. Christina broke off the kiss, and Sarah hastily discarded bra and knickers, leaving her wearing only her hold-up stockings. Christina laid back on the floor, legs spread. "Eat me. Alex, give her what she needs." Sarah got down on the floor, hips raised slightly, and buried her face in Christina's crotch. She ran her tongue hungrily around the lips of Christina's sex, then started to lick her clit. She felt Alex's weight on her back, and the swollen head of his cock slipped between the lips of her sex. She gave a muffled groan and started to lick Christina faster as Alex started to thrust inside her. Sarah felt Alex's breath hot on her neck. "Tastes good, doesn't she?" he whispered. She thrust her tongue into Christina's sex, tasting her juices mingled with Alex's, then gave another muffled groan as Alex pushed deeper into her sex, filling and stretching her. Alex's cock had never felt this good inside her before, and she could feel a growing heat and tension inside herself. Christina's moans of delight at Sarah's efforts grew louder and more desperate, and her fingers curled in Sarah's dark bobbed hair, nails digging into the back of her neck. "Yesssss..." hissed Christina. "Pleasure is all..." Sarah moaned more loudly, still muffled by Christina's sex. Alex's cock was sinking hilt-deep inside her on every thrust now, and she could feel herself fast approaching the point of no return. She licked faster, pressing harder on Christina's clit. Alex's cock started to pulse inside Sarah, the sensation of his hot come splashing into her tipping her over the edge. The hardest orgasm Sarah had ever had exploded through her, her sex hungrily milking Alex's cock. She was vaguely aware of Christina's nails biting into her flesh and a sudden chill washed through her body, leaving her feeling bizarrely weak. * * * Alex pulled his cock out of Sarah's sex, and blinked with surprise. He was still hard. Christina smiled at him. "While you're all slippery, you could stick it up my arse," she said, rolling over and raising herself up on all fours. Alex grinned and knelt down behind her. He rubbed the still-wet head of his cock against her anus and then pushed into her with surprising ease. Christina groaned with pleasure. "Oh, yes, Alex. Fuck my arse as hard as you like." He needed no further encouragement. He grabbed her hips and started thrusting hard, relishing the tight grip of the ring of muscle on the shaft of his cock. "Bet you never did this to your girlfriend," gasped Christina. "Bet she never even let you stick a finger up there. Come in my arse, Alex." Alex groaned, thrusting harder and faster as he felt his balls tighten. He couldn't believe how good it felt to have his cock buried in Christina's arse. His cock started to pulse, and he felt her anus clamp around his shaft as he spurted come into her bowels. A deep, biting chill washed through his body, and he collapsed on top of her. The world seemed to be fading into darkness around him. "I love it when a man shoots his soul into me," purred Christina, and oblivion claimed him. * * * Sarah stared wide-eyed as Christina wriggled out from under Alex. "What did you do to him?" she asked. Christina smiled ferally, eyes glowing scarlet. "He came so hard up my arse that he emptied his soul into me as well as his balls. Get up on all fours." Sarah pulled herself up onto all fours, wondering what Christina was going to do to her. Christina knelt behind Sarah and started stroking her buttocks. "Shame, really. You could do with a good buggering. Still, Mistress Denise says Master Andrew's cock would look even better in your arse than Alex's would have." Sarah swallowed hard. "Denise... wants her brother to fuck me up the arse?" Christina began to fade away. "Yes. She wants you to meet them at the circle tomorrow night."
