We were supposed to have a drinking party with our neighborly couples, but our partners ended up working late, leaving me and Yuki-ne, the neighbor's wife, to have a spontaneous girls' night. As Yuki-ne got drunk, I ended up comforting her, and in a moment of drunken confusion, she kissed me instead of her husband! Her alluring thighs peeked out from under her dress, and her vulnerable state aroused me, leading me to push her down and take things further. Meanwhile, Yuki-ne, despite regretting giving in, couldn't shake off the excitement from that night. We indulged in intense fellatio, memory-fueled masturbation, toy play, and a pounding riding position... a forbidden sexual encounter fueled by infidelity, culminating in five explosive shots.
