A lithe, smooth twink straddles his hunky partner, guiding the massive, throbbing cock towards his eager, puckered hole. With a deep breath, he lowers himself, feeling the enormous girth stretch his tight ass, inch by inch. The twink moans in pleasure and pain, as he begins to ride, his own hard cock bouncing with each movement. His partner grabs his hips, thrusting upwards, filling the young man completely.
