This is what 2 weeks of orgasm denial looks like when you finally let him cum. I laid my gloryhole board on top of him and sounded his cock through it.
This beaded rod is my goto. I really like watching his body language, moans, and timings for how long it takes him to ejaculate. yaaaa, the beaded tends to shorten the session, but it allows for more intimate edging and increase in sensation.
