Two young, smooth twinks, siblings by blood, find themselves alone and horny. They start with tender kisses, their tongues exploring each other's mouths, hands roaming over toned bodies. One brother, with a mischievous grin, pushes the other onto the bed, straddling him. He grinds his hips, their hard cocks rubbing through their shorts. They strip each other, their eyes locked, full of lust. The toppy brother lubes up and slides his raw cock into his sibling's tight hole, fucking him hard and deep. The bottom moans, taking every inch, jerking his own cock until he cums, his load coating his abs. His brother pulls out, stroking his cock until he adds to the mess, his hot cum mingling with his sibling's.
