You can simply tie her up in the basement in that position for 3 or 4 hours, go to the bar with your friends, and on the way back, your slut will be a flood of tears asking for forgiveness, and she will be eager to kneel down and give her master a good blowjob, in submission sign.
Oh, her moans of agony!
Her pain is so apparent, her cunt must be beyond excruciating with regard to pain. But yes those tits did got off easy. I would like to witness her full struggle on that particular day. Btw the model was very sexy with her her whimpers and moans of agony.
