The clinic's silence is shattered as the twins' moans echo off the cold, sterile walls. The younger brother lies back on the exam table, his legs spread wide as his twin teases his tight hole with gloved fingers, lubing him up with cool gel. He replaces his fingers with his thick, hard cock, slowly pushing in, stretching his brother's virgin ass. They find a rhythm, the older twin fucking him deep and slow, his brother gasping and clawing at his back. They switch places, the younger twin eager to top his brother, fucking him hard and fast until they both cum, their bodies shuddering with release, leaving a mess of semen and lube on the exam table.
