Gary joins his mom and dad with Bernie

He could hear as he approached the master bedroom that his mom and dad hadn't waited for him.

"Mm, mm, mm, mm..." Veevee said, her voice rising in little muffled sighs. The dull slap of flesh on flesh sounded in the same rhythm.

Gary walked into the master bedroom, gently closing the door. He felt keyed up, walking into the scene, even though he'd been invited, even though he'd said yes. He'd heard his mom and dad doing it before, and even seen them together, a little, in dark cabins or hotel rooms when the family was on vacation together, and quietly masturbating along with them. He closed his eyes, took a few deep breaths, and opened them, stepping forward until he could see the bed.
