WAAA-621 - Her sister (shy, introverted, no sexual interest) was deeply immersed in coercive sexual acts, brought to extreme orgasm, and finished as a bodily fluid receptacle. Kitaoka Karin.

*I had high expectations because it's a series with my favorite actress! My sister's boyfriend has a weird hairstyle and is overweight, so it's hard to see the joint because of his lower abdomen, so he doesn't use his hips a lot, and the delivery man's cock is big, but it's half erect, and he's a terrible actor! Karin has no interest in sex and is frigid, but she doesn't resist until her breasts are touched, her clothes are taken off, and she is cunnilingus fucked! He's my sister's boyfriend after all, so I have to dislike it and resist it a little! The scene at the end where she has sex with her boyfriend next to her sister sleeping is a classic scene, but the sister wakes up in surprise and just watches from the side, and the two of them just have sex without saying anything! Deducted 2 points because the two actors and the direction are poor.
