When I'm bound and gagged and Martin starts talking about stroking his cock as he checks me out, lets me know he's pleased with the way I look. Makes the big gag, the welded elbows, the tight crotch rope and the ponytail pulled to my arms all worth it. Knowing that my suffering makes him hard and that I'll be cumming just like this very soon is all the motivation I need to endure whatever he puts me through.
