The younger sister of a female student is sleeping with her panties fully exposed. The brother, excited by the sight of his sister's naked lower body, immediately grabs his dick for a wank session. However, he is quickly noticed, and his sister treats him like 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 it' and gives him a handjob and blowjob. But since the brother can't seem to cum, his sister, fed up with waiting, says, 'I can't let you insert it, but I'll let you wear it!'
