Coming out of shower in my gym, looked at my drink bottle and realised the neck looked just the right size. So... no one there... slipped my flacid cock into bottle, squeezed out some air and pressed against me. In no time at all, cock was engorging. Kept taking it out to check and yes it really was working. Had to hastily put it away when guy came in.
Couldn't wait to try some more at home. Result - it really does work as a sort of penis pump! Indeed after a good 20 mins of applying, squeezing air out and pushing bottle up and down managed a good cum into bottle. Super fun!
Now take bottle into shower after every gym session. Empty water, apply to cock, shower. By time I'm out of shower, cock is 2 or 3 times normal flacid size! PS remember to take bottle off before opening shower curtain. (Yes - showers are private!)
Not interested in displaying to other guys but like the effect it has on me!
Any bottle with wide neck seems to do the trick.
Would love to hear of anyone else trying this.
