SIS-105 - 4 hours of sister-brother sex - A record of a younger brother's fantasy of wanting to have sex with his older sister

Cast: Koi Mizuki / Satomi Ayase / Aki Sasaki / Seira Kamikawa / Yuzu Kitagawa / Arisa Hanyu / Miho Sakazaki / Rika Asari / Yuri Sasahara / Hatsune Imai / Mao Hamasaki / Hikaru Konno / Yui Oba To pick one scene, it starts with a 2-man:2-woman 4P with Koi and Satomi. Even though they're in separate rooms, the sounds are leaking everywhere... (lol). Both sisters are overflowing with eroticism, and since it's a compilation, it's great that it gets straight to the sex scenes!! At the end, he even attacks his own sister. No foreplay like blowjobs, just straight penetration, sudden kissing, and intense, rapid hip movements—it perfectly captured the eroticism of one-sidedly attacking a beloved sister. It would've been even better if they had done a 4P, though...
