fuma slowly inches himself down onto your strap, moaning softly as he feels you filling him up fully. he starts to pick up the pace, moans getting desperate as your hands hold onto his hips, serving as a reminder that you are still in control although he's setting the pace. you lightly slap his thigh, hearing his moans get slightly louder than before, hips moving faster as he takes in the pain. fuma's moans turn to whimpers as he feels the pleasure heighten, abs clenching furiously with every movement. unfortunately, you made him wear a chastity cage, so he knows that he would not be able to get a satisfying orgasm out of it. after awhile, fuma changes his position, back facing you as he grinds onto your strap. he leans back a little, gripping your arms for stability as he rides you more desperately. at one point, he lets out the loudest moan of the night, body furiously shaking in your hold as he feels your strap aim directly at his prostate. he straightens his legs while you take this chance to hold his ass up and fuck into him once again. fuma's moans increase in frequency and pitch, before his legs shake tremendously once again as he lets out a choked off moan.
