Dildos without suction cups.. still good for a ride?

locking suction foot rest
dose it really hold the weight of your foot

I don't even get what surface you can put the suction cup on to ride it comfortably...

Off the top of my head, I'd suggest buying a Tantus vibrator (they're actually dildos with bullet holes) and their Suction Cup. It can be used with non-Tantus toys too if they have a bullet hole. Here's a link Also Sex In The Shower made this double sided suction cup that I want, but I don't know if it's still in production and its reviews aren't exactly glowing.

They're not realistic though, so my other suggestion is to get harness friendly dildos, get a thigh/foot harness and use a chair or get one of those cushions that hold the dildo so you can ride it. I think I'd go with the sex cushion if I really liked to ride my dildos. It's pricy, but you can use it with almost any dildo rather than just the one suction cup toy.

Good luck!

I'd recommend the Doc Johnson Original Vac-u-lock it's a great dildo, made even better when you buy the option suction cup.
