Her girlfriend and her friend's boyfriend were supposed to go on a trip, but on the day, her friend's boyfriend couldn't go because of work, so three people ended up staying in a hotel in one room. She was curious about her girlfriend Rin, who looks lonely, but after a long time she stayed overnight with her, she had sex so that she wouldn't notice! In fact, Rin-chan, who was listening to this with her eyes open, seduced her! I'm getting aroused too... I'm in the river and I'm sleeping right next to her, but she's even creampied...
