I watched as he spoke, his adam's apple bobbing in perfect. Trying to contain my excitement, but feeling my erection grow I swiftly told Carlisle I needed to shower, and ran upstairs to my bathroom. Turning on some music I stepped into a boiling hot shower, being vampire I enjoy the extreme heat. Leaning back on the shower wall I begin to fantasize of his long hard cock shoving harder and harder inside my tight ass and I whimper.
Slowly I begin stroking my own dick, which wasn't a bad size. Thinking of Carlisle's cock rubbing against mine I began to pant and increase speed. At this point I am outright moaning and I begin to moan Carlisle's name. I'm pumping hard, just started moaning his name, when a hand covers my mouth and spins me around. A strong arm wraps around me to grab my ass and I'm pushed against the wall and an erection. At this moment I'm staring into the eyes of Carlisle Cullen and I almost lost all control.
A low growl erupted from his throat and he turns around sticking his ass out, pumping his own cock. Spreading him apart and using some lube I had within reach, I start pumping fingers into him. Once he was moaning with three I lube my dick and start to slide into him slowly and soon I'm fucking my dad for all intents and purposes. I head Carlisle moan out a "cum inside me" and I lose everything, and with two more thrusts I am spilling into him.
I slide out of Carlisle and he kisses me. I drop onto my knees and take him into my mouth, smirking and knowing he is about to cum. Growing slightly hard again as Carlisle keeps thrusting into my throat, he finally moans out one last, "Edward!", and cums into my mouth and onto my chest. Grinning we proceed to wash each other and begin to wonder why we don't have more "father - son" moments.
