When I rang the doorbell to give a melon as a moving-in gift, I was shocked... her breasts were as large as the gift itself, even through her clothes. As a huge tits lover, my heart raced. However, seeing her ring, I was disappointed that she was a married woman. A few days later, while doing laundry on the balcony at the same time as my neighbor, I caught a glimpse of a bra of a size I'd never seen before; just seeing it made pre-cum leak from my glans. My imagination ran wild. On another day, a bra landed on my balcony... this size, there's no mistake. I intended to return it immediately, but before I knew it, I was rubbing my cock against the bra while imagining the slutty tits of the M-cup housewife next door. The next day, returning home during a sudden rain shower, I found my neighbor struggling to get into her room, so I entered through the balcony and unlocked the door. I gasped at the sight of the housewife in a sheer bra. She said, "You're always watching, aren't you? The bra you picked up the other day smelled a bit." While flustered, I touched her, and finally, I lost myself in kneading and sucking the long-awaited M-cup tits. The neighbor also seemed sexually frustrated, and we devoured each other. From that day on, whenever she hangs out her melon-sized giant bra, it became the signal that her husband is away and it's time for an affair.
