My stepdaughter's tight pussy made me cum hard

After a long day at college, I returned home to find my stepdaughter waiting for me. She's always been a bit chubby, but I've never minded. In fact, I've always found her rather cute and adorable. But today, as we started talking, something strange happened. Her pussy suddenly started to twitch and pulse, almost as if it was calling out to me. I couldn't resist the urge to reach out and touch her there. As my fingers met her moist warmth, I felt an overwhelming rush of pleasure coursing through my body. I quickly undid my pants and plunged my cock into her tight, inviting hole. The sensation was beyond anything I've ever experienced. Her fat, yet enticing pussy enveloped my throbbing member, driving me to the brink of ecstasy. With each thrust, my climax grew stronger until I finally filled her with my hot, sticky cum.
