The younger sister of a female student is sleeping with her panties fully exposed. Excited by the sight of his sister's panty-less state, her brother immediately grabs his dick for a jerk-off session. However, he is quickly noticed, and his sister labels him as a pervert for lusting after her, but she gradually starts to feel sorry for him. Thinking that her brother might turn into a sex offender if left like this, she says, 'Are you pent up? Let me help you release' and gives him a handjob and blowjob. But since her brother can't seem to cum, her sister, fed up with waiting, says, 'I can't let you insert it, but I'll let you wear it!'
