JUY-903 My wife's older sister boldly and audaciously seduced me into an affair, causing me to orgasm in silence, overwhelmed with pleasure.

The wife's sister, Yuko, who ran away from home due to a marital quarrel. It seems she has some issues... At first, she kept her mouth shut, but as the alcohol flowed, her true feelings spilled out. 'We're sexless.' As it turns out, I'm also sexless, and it didn't take long for us to start a relationship given our mutual frustration. However, Yuko's desires began to escalate. Stealing moments from my wife, in the bathroom, the closet, even next to my sleeping wife... I was writhing in agony, with both my sanity and dick on the verge of exploding.
