"Fuck you. Just... fuck you."

"Haha! That's some pretty big words from a dude who hasn't done shit. You're just watching me fuck your girlfriend. Hey, you're even hard! You're getting turned on by this, aren't you, faggot?"

All three of your sets of eyes dart down to your crotch, where your cock has indeed grown hard in your pants. The sight of Caoimhe being used, Tyler's large dick, the smell of sex, the humiliation...

"Oh," Caoimhe says, surprised. "He is hard. I... oh shit, oh shit, I'm cumming! Ah!"

Caoimhe's whole body rocks on the end of Tyler's dick, his cock rammed deep inside and no doubt pressing against her most intimate folds. Caoimhe gasps and cries out, wincing in pleasure as she's incapable of even downplaying how hard Tyler is makin her cum. Tyler groans, before sliding his cock out of her, and pulling her to her knees roughly by the hair. As his cock pops right to her eye level, on instinct Caoimhe opens her mouth as wide as she can, sticking her tongue out. Tyler's cock fires, spraying strings of cum forward, roping across your girlfriend's face, running down her nose, splashing across her eyelashes and messing up her hair. After a few quick strokes, Tyler's cock spasms for its last shot, spurting a burst of cum into her mouth, as Caoimhe's left there, her face plastered with cum.
