No pain no gain for strapping young stud as sexy mistress punishes him

Handsome stud was working out at the gym when mistress came in. As mistress wants to know stud's sturdiness, he is ordered to strip and made to do push ups with mistress sitting on top of him! Mistress takes pleasure in training up dude's boner by placing weights on his bounded cock and pounding stud's anal tunnel with a giant strap-on. Such tough training indeed!
