Watching my stepson indulge in sexual acts with a young girl

I've always had a strange fascination with my stepson's sexual exploits. It's not exactly the most ethical thing to admit, but there's something about the way he interacts with young girls that just gets my blood pumping. I find myself constantly finding myself in the same room as him, eavesdropping on his every word and watching as he brushes up against them, his hands wandering over their soft curves. It's not just about the act itself, it's the anticipation, the build-up, the forbidden nature of it all. I can't help but get turned on by the sight of him pleasuring them, his skilled hands working their bodies into a frenzy of pleasure. Watching as he takes them, one after another, is a sight to behold. The way he fucks them, his cock sliding in and out of their tight, welcoming holes, is enough to make anyone weak at the knees. But it's not just about the fucking, it's about the anticipation, the build-up, the forbidden nature of it all.
