Katherine sticks around

The couple isn’t forcing her to participate and they would probably demand their money back from Sabrina if she bolts now, but where would that leave her? She still has no clothes and no money. She might as well stick with it until the end. Despite not asking to do this, Katherine is already in the thick of it and the girl already gave her an orgasm, the least she could do is return the favor.

“What is it you want me to do?” Katherine asks the girl in the swing, feeling a little dirty for giving in to the sexscapades so freely this time.

The girlfriend sits upright, in a more conventional swing position. She nods her head to the pile of toys Russ had laid out earlier. “Put on that strap-on, I want to get DPed on this thing!” she tells her.

“Alright…” Katherine agrees. She starts to wonder how she even ended up in this situation. Just a week ago she had been living a normal life, then she got thrown into a depraved, debaucherous world, being **** to do unspeakable acts with her sisters! Is putting on a strap-on to join another woman and her boyfriend a normalized act for her now? She is shocked at the thought that she is no longer shocked at committing these debased acts.

Katherine pulls on the strap-on and synched it in place. Something she would never have been able to figure out a week ago. She goes over to the couple. The boyfriend is steadying his girl from behind so that Katherine can face both of them. The swing gets height adjusted for the strapped woman and the girlfriend is eased onto her glossy plastic cock.

“Oooh!” she coos, stretching her legs out wide as she sinks onto Katherine’s cock. Katherine swings her hips and it bumps against the girl’s pussy. The girl bounces off and on again, giving more moans. Behind her, the man slides his stiff cock up her ass, causing her to shiver with pleasure. Katherine can see both their faces, which are in sheer ecstasy.

Katherine and the boyfriend sandwich the girl between them and start to bounce her off their cocks. It is easy since her weight is being held by the swing. She is able to sink back down due to gravity and then get bounced up by their mutually thrusting hips. Katherine and the boy are able to synchronize their motions and soon, the girlfriend is reaching the height of her pleasure! She is panting and moaning, her breaths becoming shorter, her pitch becoming higher. Her legs are splayed, feet up in the air as high as she can lift them. She clings onto the arm rests to pull herself up and slams her hips down onto the cocks. Her whole body ripples upon impact.

“Ah! Ah! Ah!” the girl cries, making the most deviant face Katherine has ever seen in person.

Katherine stabilizes herself with the metal frame, straining to keep up with the girl’s frantic bouncing. Soon, the girl’s body stiffens up and she goes silent. For a second, Katherine thinks she might be having a medical issue, but then the girl lets out a deep groan and shudders.

“AAAAAOooooH!!!” she moans.

Katherine and the boyfriend give a few more thrusts, but it is obvious to both that the girl is spent. They pull out.

“So… I guess that’s it then?” Katherine tells the two hopefully as she strips off her strap-on.

“Not quite yet…” the man says.
