Three straight slaves are brought along to the Mansion for Mistress Sidonia's consideration by Lady Nina and Mistress V. The Mistresses have decided to have a party and the theme for their entertainment will be forcing their straight slaves to orally perform for their amusement, initially on their strapons before being cajoled, beaten and tricked into sucking each other's cocks! Psychologically controlled, they tread the path from strapon to condom covered cock, to no condom, to receiving a mouthful of cum. The result, a most satisfying party and straight boys pushed further than they ever dared to go before!
