I love to lick my finger till it's all wet, like your dick normally would be without cage, and then slowly glide over your dick's head. then I just have to wait a few seconds and it will press against the metal from the inside, till it starts to hurtðŸ
I put him in his "Teasing cage" and had a lot of fun with him. He even got the chance to "fuck" me. This cage is absolutely useless for every day use, but for teasing and playtime it's just perfect.
