Whatever you get, make sure it's pre-opened for him. The best ones have an opening big enough for your pinky without stretching it. Anything smaller is hard to penetrate, will not last and is guarenteed to tear.
I just chucked a Briana Banks Pussy & Ass by Doc Johnson. What a piece of junk. The opening was too small for a pencil. I'm only 5 inches and I could not get my dick into it. I had to cut it with a knife(as serial killer as that sight must have been).
UR3, cyberskin or pleasureskin is a must! Silicon is junk.
