No constraints, no manipulation, just friends who want to satisfy their desires through sex. Ai Hongo, SONE-367

What is our relationship…? Yuta and Ai, best friends who get excited during games, where there's no pointless interference, no imposed values, and they can mutually agree on the smallest topics and true thoughts. They can talk about anything effortlessly, and one day they crossed the line. "We had sex… but we're still friends, right?" This isn't love, nor is it friends with benefits; they began an ideal relationship between a man and a woman… "No… my private parts are so compatible with yours…" Friendship between a man and a woman can exist… I've always believed that… But no matter how many times I ejaculate, I'm still incredibly excited by that perfect body… that sensitive private part is irresistible… that overly lewd oral sex and riding position… everything is perfect… We've gone beyond friends with benefits and become each other's best friends.
