There is something inherently satisfying as I continue to fuck Zac while talking to his mother on the phone. He tries to muffle his sounds, but the constant tapping against his prostate has him drooling. I watch my cock appear and disappear while his hole struggles to accommodate my girth as I end the call. I flip Zac onto his back and have him hold his leg high, giving me full access to his boy-cunt. I lick my palm and grasp his cock. It isn’t as thick as mine, but I notice that his nuts bounce the same way mine do when I jerk off. I stare down at him, holding onto his thighs as I fuck. I created this asshole, and now it feels like it is being customized for my cock, every vein carving into him like a key and its lock. I’m drilling him when my cock goes suddenly rigid. “You’re going to make me cum!” before filling him with our shared DNA. Zac was in a fuck stupor, still moaning and mumbling from the pounding. I sit back and admired my handy work. His lightly hairy hole dripping my cum, coating the ass-lips in glaze. He whimpers as I push some daddy ooze back inside and lay on top of him. “You make the cutest whimpers,” I whisper to him and lean forward to kiss his parted mouth. Drained, I wrap my arms around him and position my deflating cock in between his freshly lubed ass.
