Richard Lennox, the dominant dad, has Frank Funsize over his knee on the sofa, his twink body squirming in anticipation. Frank's skinny legs kick slightly, his short, brown hair ruffling with each movement. Richard's large hand, rough from years of experience, smacks down on Frank's bare ass, leaving a red, hand-shaped mark. Frank gasps, his cock twitching against the couch. Richard continues, his rhythm steady, his voice a low rumble, "You've been a bad boy, Frank." Frank's ass jiggles with each impact, his skin turning a delightful shade of pink. Richard's own cock throbs, eager to replace his hand, as he continues to discipline his stepson.
