I pleasure my stepson's sizable member, finding joy in observing his self-pleasure

I'm not shy about indulging in some self-pleasure, and I take great pleasure in observing my stepson as he pleasures his sizable member. It's a sight to behold, his strong hands working magic on his big cock, each stroke bringing him closer to the edge. I can't help but get turned on by the sight, and I often find myself joining him in his private sessions. His big cock is a marvel, a testament to his masculinity, and I can't resist the urge to taste it, to bring him to the brink with my skilled lips. We've explored various positions, from cowgirl to doggystyle, each one more exciting than the last. And when he finally releases his hot load, it's a sight to behold, a testament to the pleasure we've shared. But for me, it's not just about the sex, it's about the thrill of the forbidden, the excitement of being a good girl while indulging in such sinful acts.
