I love the desperation that chastity and orgasm control elicit. The promise of an orgasm is always laced with fear when it falls from these lips. His initial excitement quickly dissolves into resignation as I explain that I'll need to ensure a clear exit for all that built up cum. He nods in reluctant agreement as I show him my collection of uthrethral sounds. Mummified from head to toe, I begin by crushing his balls in my merciless crusher. I keep him hard as I start with my smallest sound, sliding it deep within his body. I slowly stroke him as I work my way up to a nice thick sound, watching fear flicker on his face with each upgrade. I slowly work my urethral plug into him now, giving him a peak at my sexy toes, inspiring him to continue doing exactly what I want. He finally released through the hollow plug, streaming a delightful stream onto his stomach and my feet. I giggle and place the weight of my feet on the crusher, one final foot show for this drained sub.
