The soloboy's eyes glaze over as he impales the doll's ass on his massive cock, the Cyberskin flesh stretching to accommodate his thickness. He grunts and thrusts, his body slamming into the doll, each impact sending a jolt of pleasure through him. The doll's anal hole clings to his cock, the tight, hot friction threatening to overwhelm him. He reaches around to grope the doll's tits, pinching and pulling at the nipples, adding another layer of sensation to his intense fucking. He's relentless, driving into the doll with all his strength, until he can't hold back any longer. With a final, powerful thrust, he buries himself deep inside the doll and erupts, filling its ass with his hot cum.
