Suffering from premature ejaculation, I was caught practicing by my sister-in-law, Nanami. She decides to help me overcome it, leading to intense daily training sessions behind my wife's back. As things escalate from handjobs to oral, she makes a deal: if I can last 15 minutes, we can have sex. Can I hold it in and finally penetrate her?




















*Nanami Kawakami likes dramas. It takes a long time and is a bargain.
The combination of Nanami-san and Yuki-san is amazing. I wish I could have this kind of 'special training' every day lol. They have such great chemistry and look like they're genuinely enjoying themselves, so I was hooked from start to finish. Highly recommended!
Premature ejaculation? My step-sister, Nanami Kawakami, helps me overcome it! In the end, we both get carried away and have an affair... The feeling of 'Is it time yet?' while being teased was so exciting.
A fantasy where a sister steps up for her sibling, undergoes intense and passionate 'special training' with her brother-in-law, gets a bit too carried away, and ends up sharing the fruits of that training with her student lol. It was impressive how serious they were about it. Hope they keep up the good relationship lol.
*I wish I had a sister-in-law like this. I like Mr. Kawakami's one-sided and kind situation.
