I found a new toy on aliexpress:

this is meant to be used to collect the cum of a Bull, but it surely works on humans too. The function is similar to a Venus 2000 Receiver. You stick you penis inside and pump up the Chamber around the liner. By pushing an releasing the Rubber bladder, you can let the tube slip up and down on your penis. I didn't buy and test it yet, but is is cheap an should be verry nice! If you have a Venus 2000 you could use it as a receiver too.
