A curious twink, bored and horny, decides to investigate his older brother's room. He finds the comforter askew and the older brother asleep in nothing but white undies. The sight of the bulge in those tight undies sends a jolt of excitement through him. He can't help but move closer, his own cock hardening. As he pulls back the comforter, he sees his brother's cock tenting the fabric. Unable to resist, he reaches out, touching the bulge gently. His brother stirs, waking up to find the twink's hand on his cock. Instead of pushing him away, he grins, pulling the twink onto the bed for a gay fuck session.
