Caught skipping class, young but very buff lad Billy is in trouble with his stepdad, but he doesn't yet know it! Excusing his truancy with fake injuries, his mum’s new husband is unfortunately a tough gym instructor who knows when people are slacking off. Demanding the lad strip and let him inspect his smooth muscular body, he finds nothing and insists he drop and give him 20 - NOW! In the process showing there's actually nothing wrong, daddy Nick is turned on by the power he wields over Billy, his dick hard already, and his focus has shifted from discipline to something altogether more energetic.
