Unseen hands grip a firm ass, spreading the cheeks to reveal a hairless, puckered hole. A thick, veiny cock presses against it, pushing in slowly as the recipient's body convulses, clenching and unclenching around the invader. The top grunts, thrusting harder as the bottom's body tenses and releases, milking his cock. The room fills with the sounds of wet flesh slapping and moans of pleasure, culminating in a guttural groan as the top pulls out, stroking his cock rapidly. Cum spurts, coating the bottom's back and dripping down his crack.
