It's been a long time since I've traveled alone as a couple.We visited a super-discount ryokan in a hot spring area.The moment I arrived at the room, I heard a woman's violent pant voice.Apparently the walls are too thin and you can hear voices from the next room...Her wife secretly goes into heat when she hears that voice.And the husbands who plan swapping.Exchange each other's wives and start sleeping.A couple flirt with each other across a wall of just a few centimeters.Pleasure that sense of immorality is transmitted and increases.The last is an irresponsible mass vaginal cum shot to another wife.
