Freedom in BDSM

Being tormented by Dee doesn't complete Marina's trials, either. PD has an he has been waiting to try out, too. Marina is almost drowning in his piss when PD decides it is time for her to get off. Orgasming without enough air is hard. Cumming when what little air she can get reeks of piss is even harder. Still, PD and Marina both know that the more challenging it is to cum the more satisfying it will be. The pain and humiliation are well worth her reward
