SSIS-247 — I Gave My Best Friend A Month To Decide If I Wanted To Have Sex With Her, But She Was So Into Another Guy That I Ended Up Cuckolding Her. Izuna Maki

This is a story about stealing a best friend's boyfriend. Nagi, her best friend, had a boyfriend named Taichi, but was obsessed with another man. She had feelings for Taichi, but backed away because he was her best friend... but when she saw Taichi's lonely face, she couldn't help but blurt out, "Why don't you just break up with me and date me?" I gave him a grace period when I heard he was going on a trip with his senior in a month. I was going to give up if he wanted to get back together... but Nagi left Taichi behind and went on the trip. So I decided to steal Taichi, with all my heart and body.
