Recently, my stepmother's daughter Mion has been growing up quite maturely after their remarriage. After her father gave her a massage due to an injury she got during club activities, she accidentally experiences the pleasure of adulthood when he uses an oil infused with an aphrodisiac. Taking advantage of her mother being away, she continues to be seduced by the aphrodisiac. Eventually, she becomes so desperate for both the aphrodisiac and her stepfather's cock that she can't help but beg him for more... Her slim waist seems ready to give out as she convulses in ecstasy! "Since you're willing to do anything for me, please go harder!"
