ninja sex 

Contrary to popular belief, ninja sex does not have to be silent. It can include plenty of grunting, yelping, ass slapping, rapid bed squeaks, and dirty talk. Only the loudest screams of pleasure are discouraged, but are allowed if the place chosen to hook up is soundproof. For example, a bomb shelter.

To cover for noisy ninja sex, a covering sound is most common, although other techniques are also used (see above). All that is required for sexuals to qualify as ninja sex is that the sexuals are undetected by others not involved in the act.

Sontia tuned the radio in her boy's room to Radio Disney when she put him to bed, and turned it up a little once he was asleep, to provide cover for ninja sex with Tony.
