DVAJ-489 My girlfriend was away from home for 3 days on a family trip, so I had sex with her friends for 3 days (tentative) Satori Fujinami

Me, my girlfriend, and her friend [Satori] often hang out. Satori is an unusual girl, and sometimes she would suddenly come to my house and then she would just sleep there, and I couldn't really tell what she was thinking. One weekend, my girlfriend was going on a family trip, so I didn't see her for three days. On the day she left, Satori and I had an affair without either of us inviting her.
