You see them both panting on the bed, the sweaty stranger laying on top of your boyfriend. They see you standing there and they start to panic. Your boyfriend is the first to speak :

"Sorry, I was sure he'd be gone before you arrived, but he lasted longer than I expected!"

While you're angry at him, the stranger also looks disappointed :

"What the hell?! You didn't tell me you had a boyfriend! Is that why you asked that I wear a stupid rubber?" He looks at you as he takes his dick out of him and says : "If I can do something for you, please tell me, I feel bad for screwing your boyfriend."

The stranger gets up and removes the filled condom to throw it away. Even limp, his dick is still beautiful... You catch yourself getting a bad idea... A real mean idea...

"Well...", you watch the stranger dead in the eyes, ignoring your boyfriend. "From now on, I'm single and I don't care about going bare..."

The stranger, who was picking up his clothes, stopped. You wonder if you crossed a line, but you see his dick throbbing to that idea.

You turn around, lower your pants and spread your cheeks, efficiently giving him total access to your hole. You feel his hands on your butt, then the hardening dick pokes you right in the hole. It's still wet and dripping its last load, making it slick. Your hole stands no chance against it, it slides in easily as his bearer lets out a satisfied grunt, as if he didn't feel an ass in a long time.

"What about your boyfriend? Will he stay there to watch me fucking you?"

You had forgotten him for a moment. He's still on the bed, shocked at what was happening in front of his eyes. He looked like he'd prefer melting into the bed and disappearing.

"Oh, he better be packing his stuff! Because once my ass is bred, I'll kick his ass out. He should appreciate my moans, it's the last thing he'll hear from me."
