It’s literally what it says on the packet…
Imagine, when having a cuppa, you dunk the teabag in and out of the water – for maximum flavour right?
Now imagine a pair of testicles as a teabag but instead of hot water, the testicles are dipped in and out of someone’s mouth!
Whilst the ‘dipping’ is happening, the recipient can lick, suck and tease the balls.
Simple!
Teabagging is often performed as a joke but is also enjoyed by many as a sexual practice.
