The woman living next door in the apartment, Monami-san (definitely single), has been really nice to me lately. Maybe... she was hitting on me～! Suddenly, she barged into my house with a dish and made me grope her I-cup breasts! W-what a slut?! As I was flustered, she pressed my face against her tits, and that's when I completely lost my mind. Wanting to see the powerful cleavage and nipples up close, I snatched away her huge bra and thrust my hard cock at Monami-san! She smiled and started a tit-fuck while licking my glans! Monami-san's sex appeal was overwhelming as she straddled me, developing into cowgirl position. As I thrust my hips from below, her watermelon-sized tits bounced in sync! Then suddenly, the guy from the next door appeared. Had Monami-san been fucking around with many residents of this apartment?! As the sudden 3P began, Monami-san's face flushed and she squirted multiple times, reaching orgasm. In short, Monami-san was an incredibly kind and overly erotic big-breasted sister.
