DVAJ-455 Since she's going on a family trip for three days and won't be home, here's the record of me fucking her friend for three straight days (tentative)

Me and my girlfriend, along with her friends 【うらら】 and 【ひな】 often play together. When my girlfriend isn't looking, うらら winks at me or rubs against me; it seems she's interested in me. One weekend, my girlfriend said she was going on a family trip, so we wouldn't see each other for three days. And just as she left, うらら and I ended up having sex without either of us initiating it. Thenひな barged in, turning my house into a temporary fuck pad for a moment. The time spent with うらら and ひな, two people with different charms, passed in an instant, and the day my girlfriend would return was drawing near.
