Seth got up and made as if to move his brother out of the way.
"C'mon, Ben, I need to fuck," he pleaded.
"I'm not done yet," said Ben.
"Dude, I've got blue balls here," said Seth.
"I said wait your turn!"
"I know one way to solve this," I said, feeling cheeky. Ben paused his thrusts but kept his dick lodged inside me.
"Go on," said Seth.
"Why don't you fuck Ben while he fucks me?"
The two brothers stared at me, then at each other.
"Okay," they both said in unison.
My cousin, Ben, still had his big dick buried in my ass when he and his brother, Seth, agreed with my suggestion. Months ago, I'd fucked Ben when he stayed at my apartment, but this was taking things to a whole new level. Never in my wildest, perviest dreams would I have expected Ben to agree to let his brother fuck him. If I'd a hand on my dick I would've cum right then and there. The two brothers, still with rock-hard cocks, stared at each other in shock.
"Wait, you're into that?" asked Seth incredulously.
"He let me fuck him once," I chimed in. "And I think he liked it."
Ben nodded with a smile on his face. Seth looked at me and then his brother in disbelief. So much realization was crashing down on Seth that I'm surprised he remained erect.
"A hole is a hole, right?" I said, winking at Seth.
"But, you'd let your brother fuck you?" asked Seth looking at Ben.
"I mean, why not? I let my cousin fuck me, why not you, too?" said Ben.
Even though the action had slowed down, all this talk about Ben and Seth fucking had me reeling.
"Just take it slow, to start," I said to Seth. "Fucking an ass is a lot different than fucking a pussy."
"I know, I know," said Seth. Ben and I both looked at him quizzically.
"I fucked my math tutor in college when I was low on cash."
No wonder Seth was so cool with me sucking his dick that one time, sounds like he's got a bit of a bi side. Seems like both my cousins do.
Seth crouched down on his knees behind his brother and spat on his dick, working the saliva up and down his pole. He spat again into his palm and worked it across his brother's hole. Seth pressed his slick meat to his brother's pucker and started to push in.
