A boy's first anal experience is a spectacle his step-mom can't miss. She watches, rapt, as he tentatively inserts a thick dildo into his tight, untouched ass. His moans fill the room as he picks up speed, his hand working his rock-hard cock in rhythm. His step-mom, aroused beyond reason, joins him, her hands replacing his on the dildo, pushing it deeper, harder, until he cries out, his ass clenching around the toy as he cums, his first anal experience etched into his memory forever.
