My step father Alex uses me like a his personal cum dump. Once he found out I like being fucked, just as much as I enjoy fucking girls, he waited until my mom was on her night shifts and entered my room. Admittedly I was whacking one off to gay porn at the time, but even so I was his step son, right. Someone he'd known for six years since dating and then marrying my mom. It didn't matter one bit as he stripped off, offered me his cock and told me "From now on when your moms not around, I'm going to fuck you".
I sucked on Alex's cock, felt his pre cum leaking down my throat, then let him flip me over to thrust his cock up my asshole after he'd tongued it for such a long time. He didn't last very long at all that first time, but he did fill my bowels with copious amounts of his cum. The following afternoon, he fucked me again when my mom took a nap on the couch. That time he screwed my asshole in the kitchen as he had me lean onto the work top. Aagin he filled my asshole up with his cum, and told me he as going to have me again that night.
We slept/fucked together all night. With Alex setting an alarm on his phone, just in case we were asleep when my mom got home. He'd only been in his own bed about half an hour when my mom walked into our house. And so it's been the case now for over eleven months. We've fucked countless times, yet it never gets boring. And he always seems to pump gallons of cum deep inside of my asshole. Lately Alex has been going down on me tonguing my asshole. After he's cum and licked and sucked out his cum from my ass, he doesn't swallow it, instead he feeds me my own cum and has me swallow every drop. It's such a horny thing that he does, that it never fails to have me wanting his cock all over again.
