While it sounds like all you're doing is offering him a cup of tea with a weird steeping ritual, teabagging has nothing to do with a hot drink and everything to do with a hot move that might drive him mad when you do it right.
Read on for Teabagging 101.
The term "teabagging" denotes the act of a woman sucking on or placing a man's scrotal sac in her mouth and sucking on his testicles. The term is obviously meant to be cheeky and humorous while the move itself can be interpreted as a little humiliating.
And yet, many couples love to perform the good ol' teabag, especially in conjunction with a hand job or a blow job. Check and see if your partner likes this sort of special attention by starting with a gentle tug.
Or... run your tongue down the length of his shaft and lick his balls without actually gathering them in your mouth. If his response is positive, you can take it to the next level.
If you're using your hands to simply tug at first, make sure to lubricate them first either naturally or with personal lube. Wrap your mouth around one of his testicles and run your tongue along the line running down the middle of his scrotal sac.
Alternate between having both balls in your mouth and having just one. Be very aware of where your teeth are and while you can allow them to softly graze his sac, keep them otherwise out of the equation by wrapping your lips around them instead, the way you would during a blow job.
For a finish that will drive him wild, suck his balls while running your tongue along the underside of his shaft. This takes a bit of practice, especially if you want to avoid locking out your jaw so start slow and scale up.
While your mouth is fully engaged, your hands are free to play. You can either lavish more attention on him by taking his penis in your hands or start to touch yourself on your genitals.
If you're a woman, use your fingers and some natural lubrication to rub your clit and pinch your nipples while teabagging your lover.
Protip: If you hum while he's in your mouth, he'll be able to feel it and it will give him the sense that you're enjoying yourself too, which will simply heighten his sexual arousal. If you'd rather be more comfortable or if he wants to get kinky, lie on your back and have him sit on your face instead of being on your knees.
While this is more of a dominant-submissive type of position, it can also be more relaxing and he can use his hands to touch you.
