There is a wonderful car called Magic Mirror in Japan. The couple who swapped there gets cum shot.

【Magic Mirror】
Magic mirror number. For short, MM number. It is a Japanese car that I use for sex.
Two pairs of couple who came there seems to play games with prize money by exchanging couple. In the subject of “naked and hug”, for honor, I embrace nakedly with partners who are not partners.
However, excitement is gaining in embracing feelings different from usual partner, and it will become impossible to quit with hug alone. At the end of the subject of “Cum Inside Intercourse With Couples Favorable”, sex started and became swapping.
Even the circumstances where you can see each other, the Magic Mirror, which is an excitement material, is very exciting for Japanese men.
