PLOT
My wife and I visited my wife's parents' house for the third anniversary of my father-in-law's death. Although it was a memorial service, we didn't actually go back to our parents' house, but my sister-in-law and her husband invited us on a casual trip home. However, our relationship has been getting cold lately... So, while I was bored at my parents' house, I couldn't help but stare at my sister-in-law An's defenseless pink nipples... Perhaps An noticed me, as she tempted me by showing me her loose chest...
