Steaming (1985)

Starts with two white girls in white robes on a fancy staircase—one blonde, one brunette, both skinny, both early 20s. The blonde is licking the brunette’s neck slow, like she’s savoring it, while the third girl walks up in just a nightgown, watching. Next scene moves to a rustic bathroom where the brunette sits on a stool in a towel and the blonde brushes her hair, fingers lingering way too long. You get a good view of the towel slipping when she leans in for a kiss. Later, the blonde is on the floor in a diaper, acting like a baby while the brunette “changes” her—full on adult baby fetish, bright lighting, no hiding anything. Last shot is a mature blonde in a crown and robe, posing like she’s in charge, but the real action is the trio on the stairs and the bathroom hair-brushing bit.
