During a break from an all-night session making cosplay costumes and wigs, my best friend's girlfriend, a fellow cosplayer, collapsed from exhaustion in another room and fell into a deep sleep. Seeing this, I couldn't resist the urge to play a prank. I started by lightly touching her body to test her reaction, and when she didn't wake up, my actions quickly escalated. I removed her panties and inserted fingers into her pussy, but she still didn't stir. Emboldened, I put on a condom and tried sliding my cock inside, thrusting several times. Eventually, the condom felt like a nuisance, so I pulled it off and proceeded to creampie her deeply, unloading a massive load inside her. Sorry, best friend. Your girlfriend's pussy was absolutely amazing.
