Taking in

In an erotic context, “taking in” means taking bodily fluids into the mouth, usually with swallowing afterwards. The term is often used in advertising for dominant or submissive roles and is a rather neutral way of describing oral practices.

What exactly is meant depends on the context. Depending on usage, this may refer to saliva, semen, vaginal fluids or other bodily fluids. As with all sexual acts, consent, safer-sex awareness and hygiene are important.
