If you've never teabagged, it can seem tricky to manoeuvre, but luckily, it can be done in a variety of positions. Let's say your partner is seated at the end of a bed, couch, or chair, and you're giving them a blowjob on your knees. In this case, your partner can simply lift and thrust their groin to dip their balls in and out of your mouth. In my experience, teabagging is most easily done if the person getting their balls sucked is standing, since they can use their knees to bounce up and down. You can also make teabagging part of a blowjob by using your hands on your partner's penis while you focus your oral energy on teabagging their balls (which, again, requires your partner to do some work, too). And while Samantha's advice about nose-breathing is certainly useful for the person doing the sucking, it can also be helpful for them to use their hands to help guide the balls into their mouth.
