As Dan was keen to see Tabi in the flesh again after her little show on Skype, and Claire was away overnight at a spa with the girls, Graham suggested he come over for some drinks and more one Friday evening.
Tabi and Beth were watching the big TV in Claire and Graham's room (aware of this, Graham now had it in in mind to fuck Tabi in his marital bed before morning); Graham, Dan and Jack - treated as one of the guys in his mother's absence - were watching Lexington Steele in action on the lounge TV. When Jack finally crawled upstairs to Tabi, waiting patiently in his bed, he was sufficiently inspired to show more consideration for her pleasure than he typically did, yet still failed to bring her to orgasm.
She waited, as always, until he succumbed to post-climactic slumber before creeping downstairs in her usual skimpy shorts and t shirt.
Jack's subconscious was still processing the dirty movie and when he stirred in his sleep, his cock standing rigidly to attention, he reached for Tabi and found her side of the bed empty. Frustrated and now fully awake, he tiptoed to his sister's room to bring his girlfriend back to his bed for another fuck. But, he found, she wasn't there either. He checked the bathroom and, finally, his parents' bedroom but both were empty.
The TV downstairs was still faintly audible. Jack sat on the edge of the bed for a couple of minutes, thinking she must have nipped downstairs for a glass of water and wondering if she would peek and be horrified at what his dad and his friend were watching, or whether she too would be turned on and come straight back to him. His cock twitched in anticipation but still he failed to hear her tread on the stairs.
Impatient, he padded down the stairs himself and quietly pushed open the lounge door.
His jaw fell open at what he saw.
Lex Steele was still fucking some MILF on the screen, but the mute button had been pressed and the sounds he could hear were not from the movie. On the lounge floor on her hands and knees, tits swinging below her, was his nude, blonde, eighteen year old girlfriend.
smile behind her, his fat cock buried between her arse-cheeks, was his father.
Kneeling behind her, his fat cock buried between her arse-cheeks was his father. "Well-lubricated, as always," he was saying. "Cheers, Jack."
Jack couldn't hear her response, muffled as it was by his father's boss's cock filling her beautiful mouth.
Frozen, he watched for several minutes, shocked and horrified, furiously angry yet unbearably aroused, as his girlfriend was spit-roasted on the carpet. He couldn't help but notice she was showing all the animation she lacked when in bed with him, grinding her arse against his father's pelvis, slurping noisily on Dan's dick as she balanced herself on one hand and stroked his balls with the other.
At length, he began to shake, turned away and trudged back up the stairs.
Back in his room he thought about his options. What should he do? Try to ignore what he had seen and carry on as before? Dump the whore in the morning with some lame excuse? Confront the trio downstairs? Drag her back to his bed by the hair and fuck her so hard she couldn't walk for a week? Call his mother? He decided it was not a decision to be made in the middle of the night, nor one he should make alone. He crossed the landing to wake his twin.
Beth, unsurprisingly, scoffed when he told her, from the beginning, what had happened. Of course her father and "Uncle Dan" were not fucking her best friend - who was also her twin brother's girlfriend - downstairs. "This is why you shouldn't watch dirty movies at bedtime," she scolded, but had no plausible theory as to why Tabi had been downstairs for half an hour in the dead of night. Reluctantly, she preceded her brother downstairs and stood, as he had done earlier, in the doorway of the lounge, staring in disbelief.
Her "uncle" Dan, on the brink of cumming, withdrew from her best friend's mouth, took a step back and held his dick in his hand as semen spurted from the tip, coating her waiting tongue, cheeks and eyelids. The girl laughed, collecting spunk on her fingers and sucking them as Beth's father, grunting rhythmically, continued to ram his cock into her sloppy pussy.
Beth, like Dan, took a step backwards, colliding with her brother. Through the thin cotton of her shorts she felt his hard-on wedge itself into the crack of her arse. She trembled, feeling her pussy moisten at the sensation her brother's cock provoked, and made to step away again, but his arms moved around her waist and his hands slipped beneath her tank-top, sliding up to cup her small, neat, round breasts. She turned her head to apologise and his tongue slithered between her open lips as his mouth closed on hers.
She struggled initially but the resistance was token. She knew it was very, very wrong to kiss her twin brother and let him touch her this way, however hurt he was, but the sight of the two older men fucking her friend was intensely erotic and she could not have stopped if her headteacher had suddenly walked through the front door. Besides, from the very first time Tabi had described to her how it felt to fuck Jack, Beth had found herself thinking differently about her brother. She had found her eyes drifting repeatedly to the bulge between his legs, spied on him as he dried himself after a shower, and masturbated thinking about what she had seen. Now, her own tongue responded to his with enthusiasm and Jack felt her nipples stiffen beneath his palms.
Jack broke the kiss but did not drop his hands and pressed his dick harder into her crack as he breathed into her ear, "Upstairs, Beth."
They turned and, hand in hand, mounted the stairs as behind them they heard Tabitha's cries of orgasm, "Oh God, Gray, I'm cumming!"
In his room, Jack switched on the bedside lamp and peeled off his twin sister's top and shorts, his eyes roaming over her naked body. He hadn't seen her fully nude since they had shared baths in primary school and both her body and his own reaction to it were transformed. She was slim and narrow-waisted, he saw, but lacked Tabi's voluptuous curves. Her small, round breasts were pale and freckled, with areolae and nipples that were typically palest pink, although right now they were red and engorged with desire. He straddled her now, lowering his mouth to suck on them, flicking his tongue over the tips, nibbling and tugging so she writhed beneath him, whispering for him to stop - but her hands holding his head in place belied her words.
He released the nipple he'd been sucking on and moistened his tongue before working over both breasts with long, lavish licks until they shone wetly in the dim light with his saliva and her whole body trembled with incestuous desire. Grinning, no longer troubled by the thoughts of his father and girlfriend, he parted her white thighs and burrowed between them. She had a pretty pussy, he thought. Tabi had told him how she had trimmed and waxed Beth's bush and she had only a small, heart-shaped patch of strawberry-blonde pubic hair. The point of the heart directed Jack to her slippery labia. He spread his sister's outer lips with his fingers. She was oozing moisture and he inhaled her scent, hungry to taste her. He sucked gently on her pussy-lips, dipping between them from time to time as his twin moaned softly, then sought her clit with his tongue. As he circled it slowly he slid a finger between her labia and into her cunt, where he immediately encountered difficulty and Beth winced and pulled away.
"Beth, you're so fucking beautiful. I want to fuck you," he told her.
"I'm a virgin," she confided, shyly.
"Do you want me to?" he asked, hopefully, and she nodded slowly.
Lust swept through him and he scrambled out of his own shorts, opening his dresser drawer to locate the lube he used when preparing to fuck Tabi's arse. He spread it all over his cock and soaked her pussy with it, pushing some inside with his fingers.
Her eyes were wide and frightened and he kissed her lips, holding her cheeks in his hands and her eyes with his gaze.
