I was in a state of boredom with my wife, and was seduced by Aika (stepsister) and creampied me many times...

My wife went on a trip alone. As the relationship between the couple is getting colder, they are unable to withstand the temptation of their wife's younger sister, Aika... Even so, the more I think it's no good, the more my rationality is blown away... In the day, at night, and in the morning, while my wife was away, I had intense sex with Aika, and I had creampies over and over again...
