My friend's tight pussy makes my cock hard and horny

I've got a fetish for tight pussies, and I've been lucky enough to have a best friend who fits the bill perfectly. She's got a body that's straight out of a porn movie, with a big, juicy ass that's always begging for attention. Recently, she's been on fire, and I've been struggling to keep my cool around her. Every time I see her, I can't help but get hard and horny. It's like she's got some kind of superpower that makes my cock twitch. I've been trying to keep things professional between us, but it's getting harder and harder to resist her. I've been dreaming about the day when I can finally take her from behind, and fill her tight pussy with my throbbing cock. Until then, I'll just have to keep fantasizing about it and hope that one day, she'll realize that she wants me just as much as I want her.
