The sister I met for the first time was a cute Japanese woman with large breasts. Unable to resist the unconscious temptation of her exposed school uniform underwear, I became aroused, and my uncontrollable sexual desire and semen were directed into her underwear, ejaculating inside. I promised to just make her wear the semen-soaked underwear, and when she wore it with only the underwear on, the freshly ejaculated semen and her sister's vaginal fluids mixed together, becoming sticky! Seeing that she seemed to feel good and aroused just wearing the underwear, I pulled it down and immediately inserted myself. Watching my sister writhe and climax while shaking her large breasts, my lust surged, and I couldn't stop the thrusting, repeatedly ejaculating inside her.








*Wearing ejaculated underwear, we have intercrural sex and sex. There are a lot of different underwear to enjoy, but the chapters are short.
*Her face, butt, breasts, and even her panties are all so cute. It also has a nice fetish feel.
Actress: Amatsuki Azu. Every single scene is shot with such care. All the panties are adorable, and there isn't a single wasted moment. The cowgirl position with her panties pulled down to her thighs in the final scene was a rare treat. The M-mount position around 2:33 is briefly shown head-on, and I wish that scene was a little longer.
Please make more sequels with this concept! I'd love to see some scenes with thongs involved.
*A highly recommended book overall. In addition to ejaculating into the crotch part of the panties, the play involves wearing them and massaging them, which is a thrilling play for those who like it. However, the aftertaste is a little short, so ⭐️ is a minus. It's okay to show a little more aftertaste. Also, I wish there was one more twist to the aftertaste. I would like to see some more aggressive play, such as making him cum with a rotor after wearing it, making him ejaculate from above his pants after making him wear it, or making him masturbate violently after making him wear it. However, overall it can be said to be a good work.
