My master/wife got this device for me to further her pleasure, tease me and through in to torture my balls when I get out of line. She lock's me in it and tickles me so that my arms and hands pull and give me a very large erection. She will then suck my dick until almost ready to cum...but she then stop and deny me the pleasure....next she clamp on ball crusher device and twist some until I howl with pain.....she leavees for a while and then sits her cunt on my cock to get a good fuck. This all happens while I am on my back and lashed at four points to the bed.
This is a great way to get it...very stimulating. I'm sure she will also come up with other unique approaches. We both give it five stars and recommend.
