Of course

I'll be honest: The fact that Allie was sleeping right there is what pushed me over the edge. I pulled my boxers down to release my throbbing cock, then gripped it loosely and began to stroke softly, thinking about sexy Allie, Laura's pierced left nipple, and Emily's vague same-sex sexual experience (which in my imagination was her masturbating to lesbian porn; for some reason I found that very hot). But my mind kept returning to the hot blonde in the window.

I stepped over to the curtains and pulled open a small gap to peek through, but the window that haunted me was covered by an opaque blind. Disappointed, I waddled to the bathroom and pumped my hard cock furiously, my eyes scrunched up as I thought about the mysterious girl's plump breasts and taut, toned stomach. I imagined what the rest of her might look like – long, smooth, athletic legs and a tight little bottom – and what it would be like to have her ride my cock, filling her as she rocked herself to orgasm. I came with a quiet grunt I couldn't quite keep in, bucking my hips as I spurted an absurd quantity of semen into the white porcelain toilet bowl.

Spent, I wiped myself up and returned to bed, sleeping soundly now in my post-orgasmic haze until morning.
