Someone is shown passed out or peacefully asleep while another character watches, cuddles up, or takes advantage of the moment. A lot of scenes lean into the contrast between a limp, unresponsive body and hands roaming over tits, ass, or crotch, sometimes escalating into oral or full-on fucking. It can read as cozy aftercare or as straight-up noncon, depending on whether the sleeper wakes up and consents.
