He opens the door and Tina's eyes widen at the sight of her sister tied up with her pussy and ass on view. He pushes her forward and signals for her to get undressed. She responds immediately, removing her top and her jeans then sliding her thong down her legs.
"I'm back sweetie. I just wanted to clean up before I go in you. I got a bit horny earlier ..."
She giggles.
"Is the door shut, did Tina see you?" She asks him.
"Tina's gone out. She said she was going to the shop so that we could have a bit of space. She thought we were arguing." He smiles at Tina.
"Oh good. We don't have to worry about the noise now!" She giggles again.
He takes the rubber strap on out of his bag and gives it to Tina, sucking her tits while she puts it on. He bites on her nipples and slips a finger in-between her ass cheeks. She smiles at him.
"Come and fuck me Mark. Fuck me hard." Leah whispers to him seductively.
He points to Tina and then to Leah before nodding. Tina gets it. She climbs onto the bed, with Mark right behind her and positions the head of the dildo against Leah's pussy. She slides it up and down between her lips so that Leah's juices are on it.
Mark slips his own cock between Tina's ass cheeks and presses against her. He loves the pressure that he can feel when he thrusts his cock between a woman's ass cheeks. He takes hold of Tina's tits and kneads them roughly. He tweaks her nipples, and nods at Leah. He positions his cock at the entrance of Tina's cunt and moans quietly as his head slips straight through.
Tina takes this as her cue and pushes the dildo into her sister's cunt. She slides it in very slowly, Leah gasps with pleasure.
"Faster Mark. Fuck me faster." She grunts at him.
Mark thrusts against Tina, pushing his cock deep into her slutty cunt. The thrust pushes Tina further into her sister and she moans quietly – in time with Leah.
Mark places a hand over Tina's mouth to remind her and leaves it there, holding her face. He pulls her head back towards him and tightens his grip with each thrust into her.
He looks at the two women in front of him.
His own wife, is getting fucked by her sister, while he's fucking his sister-in-law. It's enough to make him cum, but he can't do it now. Not yet.
He grabs Tina's hips with both of his hands and rams his throbbing cock harder into her with each thrust. He grunts as his balls hit against her ass.
"Oh my god. Mark! Yes!! Yes!!" Leah shouts out as Tina rams her dildo further into her with each thrust that Mark gives to Tina.
He squeezes Tina's ass cheeks roughly while fucking her from behind and decides to swap positions. He pulls out of her, pushing her forwards slightly – but making sure that she doesn't touch Leah. He kneels behind her and positions his swollen head against her puckered anal hole.
Tina thrusts against his cock with each movement in Leah, the tip of his swollen head pushes against her hole harder with each thrust that she makes and as she comes back with one hard push, he feels his head slip through and into her ass. He grabs her hips and forces himself all the way in with one big push, not caring if he hurts her.
He moans as his dick continues to reach up her passage until his balls are reasting against her pussy then he humps himself against her cheeks, not wanting to bring even half an inch of his dick out of her.
Tina's head rolls and she shudders. She pulls her dildo out of Leah and without any hesitation, she lowers the dildo to her sister's little pink hole and pushses.
"Arghh! Argh! Mark!!" Leah screams, thrusting her ass against the dildo, pushing it in further. "Oh my god!!!" She screams louder.
