[Project description] It seems that there are some fierce guys (couples) in the world who practice perverted play that puts AV to shame in private... Just how deep a relationship do they build... A practical documentary that pursues the truth Variety! !This time, I pretended to be an amateur to apply for an orgy party thread on a bulletin board, and tried sneaking in with a hidden camera.In addition to single participants, three couples seem to be participating in this party, and the women are all beautiful.Among them, I was unintentionally excited by a pretty woman who shakes her well-shaped breasts and does yoga with pleasure.She was the organizer's girlfriend, Mirei (pseudonym).After the end of the orgy party, I decided to directly hit the host couple and ask them about it.It seems that he persuaded Mirei, a former campaign girl, to take her to an acquaintance's orgy party. The more they go on a date.and later.This time, I received information that I would enjoy swapping with another couple 3 VS 3, so I asked them to stick to it.Unlike an orgy party, you can peek at each other's SEX up close.Excitement doubles with pounding, guilt and pleasure.Both couples enjoyed swapping to their heart's content.To the two who deepen their love for each other through swapping and orgies, this time I proposed an orgy party.The content is an orgy party of 2 men and 2 woman, which they have never experienced before.Mirei was also very excited about this proposal.What will happen to them after this...!? ?
