For about half a year Sir will only finger me while his cock is in my throat so I had to learn to cum while gagging on his cock and now I can't cum without it! Even when I masturbate by myself I have to jam fingers down my throat to cum.
If I crawl fast with good form I get the hitachi, if I don't - first I get my anal hook pulled on, and then for safety reasons, the clip is clamped to my nipple to shut off the treadmill
