Karen, playing an adult volleyball club member, gets injured during practice and visits a nearby chiropractic clinic. The therapist waiting for her is a pervert. Too timid to say no, she endures massages of her groin and breasts that clearly have nothing to do with the injury. As the treatment grows more sexual, she wonders whether it is really therapy, only to discover her panties soaked. The chiropractor inserts his cock and keeps developing her sensitivity while she passively submits, until she is spraying fluid and exposing one humiliating orgasm after another.
