Espio, the Chameleon, sneaks into the room, finding Sonic and Knuckles in the throes of passion. The sight of Knuckles' massive cock buried deep in Sonic's ass, the blue furry's tight hole stretched wide, sends Espio into a frenzy. He can't help but join in, his own cock hard and ready. Sonic, eager to please, takes both Knuckles and Espio's cocks in his mouth and ass, riding them both in a furry gay anal sandwich. The room fills with the sounds of their moans and the slapping of flesh as they all chase their release, ultimately collapsing in a spent, cum-filled heap.
