My sister-in-law brings a girl over to have sex with me. (AI TRANSLATED)

Kikusaki Shihime, an 18-year-old sister-in-law known for her beauty mark and athletic confidence, surprises the male lead by bringing her shy, bespectacled friend over for sex, turning an awkward proposition into a charged encounter. What begins with nervous excuses and flushed introductions quickly becomes an increasingly explicit play between the two women and the man, with the friend's full breasts, teasing mouth, and eager attention igniting tension between all three. By the closing exchange, the friend is asking to be cared for “for a long time” and not excluded, suggesting that the casual setup has opened the door to a more complicated, lasting arrangement.
