This is seriously something that I think every one should own; bottom and top alike. However, there is really no excuse why every bottom does not already have one of these.
Years ago, I bought a triple pack of smaller sized “lube injectors” (I like how they call it a launcher, I guess it does launch the lube up your hole) but I ran into the problem that they wouldn’t reach the bottom of the lube bottle. Tipping over the bottle and trying to suck the lube up the injector tube was a clumsy task.
This tool is super handy because it gets rid of a lot of the mess and it gives you the opportunity to pre-lube before you head to your favourite event without being all sticky. (I know sometimes being sticky is fun) So then you pretty much just need to “spit and push” and you are on the way to a good time.
It is also really great fun to play with when you have a gentlemen caller or callers over. Let you imagination run wild.
