Vivien being fucked in a sex swing.

You're in a bit of shock as you see Vivien, completely naked, being held up in the air by what you can only assume is some kind of sex swing, as her husband, Dan stands in front of her, swinging her back and forth, his cock clearly inside of her.

You continue staring as Olivia fully enters, closing the door behind her. She seems a bit surprised, but not nearly as much as you. The two of you watch Vivien's head tilt back as a long moan escapes her lips. Dan fully controls her swaying as he thrusts.

You're unsure of what to do, surely they know you're here, but you also don't want to interrupt them. It's not long before you realize you're just watching. Vivien's arms are raised against her head, seemingly tied onto the swing, along with her legs that are stretched out to the sides far enough to give Dan space between them. He picks up the pace, moving his body more along with the sways of her body.

"Ooooh Yeah!" Vivien moans.

You look over at Olivia, who is also watching. She has a look in her eyes, and overly intrigued look, as she watches the acrobatic sex display in front of her.

The two's speed picks up even more, Dan's motions getting quicker and shorter.

"Are you about to cum baby?" Vivien says between heavy breaths.

"Oooh yeah!" Dan grunts "Do you want it in you or on you?" He asks.

"COVER ME WITH YOUR CUM BABY!!!!" Vivien shouts.

You can't believe you're watching this.

Dan pulls her in hard before quickly pushing her body away and off of him. He quickly takes his cock in hand pointing it directly at her. He gives a couple quick tugs before cum is shooting out. You watch as it splashes against Vivien's face, it continues to spray down, coating her chest, eventually stopping with a light stream flowing into her bellybutton.

"Oooh honey, that was amazing!" She says taking a deep breath. She slowly turns her head, brining her eyes directly towards you. "Don't mind us." Vivien says, in a completely casual tone "We were just working up our appetites."

Dan leans over and begins releasing her arms from their restraints.

"So glad the two of you could make it." Vivien says moving her now free arm and helping Dan with the other straps.

"Happy to be here." Olivia says,

You don't know what to say, so you simply continue waiting for Vivien to get out of the swing, no longer worried about being the one to make things awkward.

"Dinner's not quite ready yet." Vivien says, landing her feet on the ground. "Would one of you like a turn?"

You're once again shocked. You have no time to answer her question as you hear Olivia speak for you.
