I've found your replacement Stephen

For some reason, i don't see robo-human loving becoming commonplace or even remotely popular.

However...Maybe it's a chance for Stephen Hawkings to find the perfect partner!
 
Dammit!! There used to be a spoof website created by a Canadian artist based on a "creature" called the Love Lump. The Love Lump, in concept, is like a blow-up sex doll, except that it's designed from real, living tissue. Oh, and it also doesn't look anything like a sex doll. While it bears all the appropriate sex organs, it's lacking a head or limbs. It's just a lump. To keep your Love Lump alive, you have to inject it with nutrients on a regular basis. They had a picture too, truly disturbing.
 
Alright, after a bit of searching, I found the sought after image of The Love Lump. Shield your eyes if you're easily offended!

Cock up the arse, dangle your wang into the snatch.. hold onto the tits.

The bit between your balls and arsehole will get pretty bad friction burn, mind.
