Latex fit on/over Dildos for Men aka strap ons which go over the penis

[Joshua1986]

Wouldn't it be good if there are not already out on the market dildos that you can masturbate into, store the sperm and then use it to insert and pleasure your significant other and have a 'special release'. That could be interesting. Say if you have a 5,5 inch penis you can get the lady to give you a handjob, cum into it and then use it to insert the 9 inch dildo into her. Or better still have prosethetics which you can put over your penis but have a tube so when you ejaculate it would go down that but make the prosthetic as realistic as possible for the ladies pleasure and also as tight fitting for the male's pleasure so that he could still be able to feel the sensation.

I posted it first on Latex Nation forum by Rubber Doll but no one responded.

Also I am not sure if there are any out there at the moment :/
