The bears' hands, rough and hairy, grip the twinks' hips as they plunge in and out, their massive cocks stretching the boys' tight holes. The sound of flesh meeting flesh fills the air, punctuated by the bears' grunts and the twinks' moans. The bears pull out, their cocks glistening with lube and cum, and push the twinks' heads down to rim their hairy asses. The twinks eagerly comply, tongues exploring every wrinkle, before the bears mount them again, fucking them until they cum, filling the boys' asses with their hot, sticky seed.
