Air Tight (sometimes written as "Airtight") is sexual group activity where a recipient has all their available holes filled by penises or phallic objects controlled by other people. This is mostly used in reference to people with a vagina as they will need three people to fill the mouth, anus and vagina. Often there are more people available to also use both of the recipient's hands at the same time, however this is not always the case.
This can be an activity during an orgy or gang bang.
