My girlfriend, her friend Riho, and I often hang out together.Riho seems to be interested in me by grabbing my hand and leaning in close to me when she isn't looking.One weekend, my girlfriend went on a family trip, so I didn't see her for three days.On the day she left, Riho and I ended up having cheating sex without either of us inviting her.After that, we had sex over and over again, trying to make up for what we hadn't had before.Other than eating and sleeping, we mostly had sex.Their time passed quickly, and the day she returned from her trip was drawing nearer.
