A twink's hands glide over the muscle bear's broad back, his fingers sinking into the bear's thick flesh. The bear's cock twitches, growing harder with each stroke. The twink's eyes widen at the sight of the bear's huge, veiny cock. He leans down, taking the head into his mouth, his tongue flicking over the slit. The bear groans, his hips bucking as the twink sucks, his hand stroking the bear's length. The bear's massive balls draw up, ready to explode. He flips the twink onto all fours, his bear-paw hands gripping the twink's hips. He lines up his cock with the twink's hole and slams in, the twink crying out, his body shaking as the bear stretches him wide. The bear's thick cock fills the twink, his body clenching around the bear's length as he fucks him hard, their bodies coming together in a symphony of grunts and moans.
