User Sharing丨Penis as hard as Iron Man?

Recently, I have certain requirements for the erection speed and hardness of my penis. It just so happened that Bestvibe put this dual-purpose masturbation + erection training airplane cup on the shelves. So I bought it as soon as possible and actually tried it for a month. Below I will share my ratings and true feelings. 

Comfortable Colors
I named this airplane cup: Sap Cup. Its spa function is what attracted me the most this time. 

Let’s talk about the appearance first. Compared with the traditional black and white airplane cup, the green color really makes my eyes shine. The transparent shell allows me to know very clearly the status of penis erection or masturbation. The overall size of the cup is: 10.3 inches. It’s no problem to put it in a drawer or wardrobe at home.
