Even though I love big tits, my girlfriend turned out to be a flat-chested sex hater. In frustration, I went to an oppai bar and, to my surprise, found her younger sister Rinachan working there. What's more, she was being served by another customer who was groping her big tits. Later, unable to hold back, I called for Rinachan, deceiving her surprised sister, and squeezed her tits relentlessly. Then, secretly in the store, I fucked her and came inside! From that day on, even at her house, I kept squeezing my giant-breasted sister-in-law's tits, turning it into an oppai bar state!
