TVR/Ken/Kids/Andrew&Susan/Janet's Ass
Janet is looking a bit shocked. Whether it's about what has happened so far, or thinking about what it would be like to have a cock in her arse, is hard to tell. The thought of it is making your cock react though.
"It's not that bad," Susan says. "It's just different. You don't want a really big one in there though, that can hurt."
Janet's squirming and Andrew is stroking his cock as he looks at the two naked girls. "Do you want to try," Andrew asks.
"Me," Janet squeaks.
Andrew grins. "My cock's smaller 'n his."
Janet squares her shoulders. "Go on then, but you have to promise you'll stop if it hurts." Andrew promises and they both look at you.
"Susan, can you get a towel and some baby oil from the bathroom please," you say. The bathroom is an extension built onto the side of the kitchen and it only takes a minute before she is back. Spread the towel on the floor and give the oil to Andrew," you say. When she sits back down you tell Janet to lay face down on the towel.
You think about the films you have seen and wonder if this is like to be a director. "If I had a cine camera, this would make a great film," you think. "Now Andrew, I want you to spread some of that oil onto your sister's bum, down between the cheeks."
Janet giggles as her brother does as he's told, wriggling about in an unconsciously sexy way. "You need to get some inside her bum-hole," Susan chips in. You beckon her over and she comes and sits on your lap to watch as Andrew gets on his knees between Janet's legs and spreads her bum cheeks apart. He dribbles more oil right onto her bum hole and then presses his finger against the entrance.
"Gently now," you say. "But you may have to push a bit to get her to open up. Andrew looks up and grins. Susan is sitting on your lap with your stiff cock sticking up between her legs. He applies more pressure and then his finger slips past her sphincter and it's in. Janet tenses up but makes no attempt to get away.
"Keep your finger in but get some more oil on it. You need plenty inside," you say and Andrew adds more to her already oily bum. "Now try another finger," you say.
He pulls his finger out and before her anus can close up, he gets two together and slips them in. Janet lifts her head. "Hey!" she says. Andrew doesn't need any more instruction and shuffles forward. Then he realises that it's not going to work like that and while keeping his fingers in place, he gets his knees outside her legs. You hear him grunting with the effort and then Janet moans into the towel as he finally manages to force his cock into her arse.
Of course, he cums almost straight away, but instead of getting off, he just lays on top of her with his cock still trapped in her bum. Janet struggles a bit with his weight crushing her and he lifts himself up on his arms. "Get off," she says.
He ignores her and stays where he is with his cock buried to the balls and his hands on her shoulders to stop her from escaping. Wriggling about is having the opposite effect to the one she wants. "I'm not done yet," he says as he starts thrusting again. His sister stops struggling and you think that she might even be pushing back as he rams his stiff cock into her spunk-lubricated arse.
"Fucking hell," he says as he finally pulls his limp cock out. "I dunno what came over me."
"You fucking came over me you sod," Janet says, turning round and giving him a shove that makes him fall on his back. "I need the toilet," she says and heads for the bathroom.
While all this was going on, your cock was firmly gripped in Susan's cunt and now the show is over she starts bouncing up and down to get herself off.
