Ass stretching with strap-ons

The loser can't be fucked the way we would like! We stick our strap-ons into the slave's ass, one after the other, but he keeps tensing up! As punishment, he has to bend over in front of Lady Adora, Lady Lexi and myself and we fuck him even harder! Because that's not enough for us, we stuff a really fat dildo into his ass until the fuck-piece collapses in front of us.
