A super sensitive stepsister who reacts erotically just by lightly touching her body or tickling her is a genuine M-type woman! Even if she brings a man home, her moans are so loud that the man, fearing he'll be discovered, leaves quickly, so she only ever gets to give a blowjob. Her stepsister, who has been in a state of extreme sexual frustration, on the verge of explosion, reacts extremely erotically just by being touched a little, and when her breasts are grabbed, instead of resisting, she arches her back in an S-shape, going into a state of continuous explosive orgasms, breaking down her rationality! She begs for a dick, twisting her body and cumming non-stop!
