My wife Ryoko and I got married at work, and this year marks our 7th year of marriage. - I am still in love with Ryoko, who is my older sister's wife. - The other day, the president of a business partner who likes me asked me to do some swapping. - This 3-year-old president has just recently married a young wife, and she loves dirty jokes and has a lot of eroticism, so I'm fine with that too! - That's what I said. - Then we actually ended up having sex... I told Ryoko that she had invited me to a dinner party with my wife, and even though I was somehow deceiving her, the day arrived. - Cheers while poking the pot. - The president complimented me a lot and I felt tickled, but his wife was cuter than I imagined, and with this person! - I was excited in a different way. - As the drinks progressed, it was time to change seats. - Ryoko was next to the president, and his wife was next to me. - While we were having some fun drinking, my wife suddenly started complaining that she was drunk and I went to a separate room with her. - At my wife's invitation, we had sex. - Feeling guilty, I went to check on Ryoko and found her doing it. - The president and Ryoko are in awe. - And it's even more erotic than usual. - But this is just the beginning, and it feels like the erotic feast hasn't even begun yet...
