Master Frederick binds my breasts and ties my hands at my waist, and then takes advantage of my helplessness... He starts by fucking my mouth super deep and gagging me, then has me sit on his cock and ride it in reverse, getting REALLY deep inside me! He slides a clear plastic bag over my head and seals it around my neck with a leather strap, ordering me to keep fucking him!! The action runs my oxygen thin REALLY FAST and I begin to panic as I suck plastic, begging him to remove the bag! I get a short break and then on goes the bag again, with me riding his dick and once again running low on air really quickly!! After he takes the bag off a second time, he fucks me on my side while squeezing my neck some more, not stopping until he fills me with cum!
