I'm sprawled across our family's ancient wooden desk, my academic papers scattered across the floor, completely forgotten. My fingers dig into the edge of the table as my twin brother pounds into me from behind, our nude bodies slapping together with wet, obscene sounds that echo through the study.

"Ah! Ah!" I gasp as Zhuge Dan's cock hits that special spot deep inside me, the one that makes my legs tremble and my mind go blank with pleasure. My own penis hangs heavy between my legs, already having released multiple times across my stomach and chest.

"You're taking me so well, brother," Dan whispers in my ear, his voice a mixture of teasing and pure desire. "Your tight little hole was made just for me, wasn't it?"

I try to shake my head, to deny this forbidden pleasure, but when he hits that spot again, all I can manage is a guttural moan. My body betrays me completely - my inner walls clench around his throbbing member, begging for more despite my better judgment.

Dan's hands grip my waist tightly, his fingers leaving bruises that will remind me of this indiscretion tomorrow. "Tell me how much you want it," he demands, slowing his thrusts to an agonizing pace.

"Please..." I whimper, humiliated by my own neediness yet unable to stop myself. "Please don't stop, brother."

He laughs softly against my neck before biting down hard, sending another wave of pleasure-pain through my body. "That's my good哥哥 (brother)," he says before slamming into me harder than before, setting a brutal pace that has the desk rocking beneath us.
