A mature woman who once had her anus developed by an older male friend-with-benefits and enjoyed quite hardcore play in the past. After that, she met her current husband and grew distant from that man. Her husband is a kind and serious man, but their sex life is "normal." Moreover, he prioritizes work and barely pays attention to her almost every day. She lacks the courage to tell her husband, who has no obsession with sex, about her past anal experiences or her own sexual preferences, spending each day in conflict. As she reminisces about the past and plays with her anus alone, her emptiness gradually increases. Just when she was wondering if something could be done, she discovered an advertisement for a filming crew. She decided to apply and consult with them, leading to today.
