Your body wants it so bad!

You look down, and see that you're tenting your trousers, rock hard.

"Oh fuck it."

Throwing caution to the wind, you advance on the butt on the left. Now that you're close, you can see that the pussy is glistening with natural lubrication. She really is wet and ready.

"What a slut." You say out loud, as you run a finger inside her labia, feeling her warm moisture.

"Both of them must be massive whores." Steve comments. "To have stuck their butts through here to get fucked."

You examine the padding surrounding the edge of the hole housing the butt in front of you. It appears to be made of some kind of inflatable material, which has inflated to create an airtight steal around the woman's thighs and waist. To be honest, it seems unlikely that she can remove her butt from this position until the seal deflates. How can you be sure that she's truly consenting to this?

Steve shares absolutely none of your concerns. He is starting to ease the tip of his dick into the waiting pussy in front of him.

"Nice and tight, just how I like it." He grabs the sizeable ass cheeks with both hands, and begins kneading the butt-flesh as if it was dough.

With every thrust, Steve is sinking his dick further and further into the snatch in front of him.

"Shouldn't we be using condoms or something?" You ask, with audible uncertainty.

The bartender just shrugs. "Have you got any on you?"

"No..." You admit. You're married and your wife is on the pill. Why would you have condoms?

"Neither do I." He says bluntly.
