An innocent trip to a hot spring with beautiful young girls for one night and two days. Their still immature pussies are forcefully developed by big dicks! Flat-chested girls having sex in an open-air bath, threesomes with big-breasted girls, and illicit sex with teachers while wearing yukatas—all techniques that make the young girls cum repeatedly! A secret 240 minutes where both heart and pussy are healed in a warm hot spring.
