More than friends, less than lovers. Living together with a big-assed female friend who's not a sex friend. One day, a female friend from my student days came to Tokyo and ended up living at my place. My daily life with a big ass suddenly began. I couldn't maintain my composure when I saw her assertive big ass jiggling right in front of me, and I immediately fucked her! It felt so good that I crossed the boundary of friendship and came inside her raw! I was totally hooked on her pussy, which was a perfect match, and we had sex every day with our instincts unleashed, and it felt amazing! Sex with a big ass is best done from behind!
