My sister's gal friends have taken over my room. They're teasing me with short skirts and revealing tops, and things are getting heated when my sister isn't looking.

















The highlight was definitely the underarm shots of the Himari and Hinako duo early on. I'm a fan of both Riria-san and Kasumi-san, so I thought it was a luxurious cast, but Riria-san only appears halfway through, and Kasumi-san is just a one-on-one scene, which felt a bit lacking. I wish the flow had been a bit better, but it was still a decent watch.
The highlight is the first half, where a 3P starts with the sister's friend after the sister goes shopping, which then unexpectedly evolves into a 4P with another friend added. The luxury of going through cowgirl, sitting, and missionary positions one by one is amazing. The thoroughness of engaging the two women who aren't even participating in the main act with both hands leaves you exhausted by the end. The second half features incest play with Kasumi Tsukino, who plays the sister. Unlike the first half, it follows a more orthodox path, but Kasumi Tsukino's unpolished vibe fits the role well. It's a masterpiece where you can enjoy two types of erotic developments in one story. The video quality felt a bit rough, but it's still a 5-star work I can recommend.
The girl in the navy bra (bottom left of the package) and the one in the pink bra (top right) let me smell their armpits while in their underwear, and then they take off their bras to sandwich me with their breasts. That scene was top-tier for me. Another highlight was the 1-on-1 chapter with the girl in the white bra (top left); her large breasts made me very happy.
The image quality is a bit poor, and the angle during insertion is bad. The double nipple licking in the first half of Chapter 2 with Himari & Hinako was superb—I really thought it was a harem—but it's a shame the quality dropped once the other actress came in.
It's a two-part structure: in the first half, you lose your virginity to three of your sister's gal friends, and in the second half, you become the first partner for your pure younger sister (teaching her what you learned from the gal friends). The sister has the biggest breasts! (Though they are pure, with small, light pink areolas). I wanted to see a 5P or 4P including the sister after she gained experience! Is that asking for too much?
