Today, I reunited with my old high school classmate Maina, someone I've stayed close with over the years. The moment I arrived at our meeting spot, I found her taking a selfie with a camera in hand. She immediately said, "Hey, long time no see! Here, you film me today," thrusting the day's recording duties onto me before I could react. Flustered, I had no choice but to accept. We headed to an izakaya while catching up, and after a toast, the conversation turned to our married lives. She joked, "Not much going on lately. After five years, that's just how it is," but her words revealed the dull reality of her daily routine. Still, her body was surprisingly voluptuous—her deep cleavage especially captivating. I couldn't help but stare, and she, noticing, began provocatively showing off as if to seduce me. Losing control, I found her hand gripping mine under the table, then touching my crotch. Her hand groped my groin, shattering my restraint. Unable to hold back, we rushed to a nearby hotel. Once inside, she teased, "This is what you wanted to see, right?" and exposed her gorgeous breasts. Her massive tits, larger than any I'd ever seen, were squeezed and fondled as we moved to the outdoor bath. She hungrily licked my body, sucking my nipples and then my cock, pleasuring me with her tits as I struggled to endure. Finally, we had bareback sex in the open-air bath, committing adultery right there. The taboo thrill of cheating with a married classmate from high school overwhelmed me, and I erupted inside her in no time. Back in the room, without pause, we began round two. When she changed into a yukata, her allure reignited my arousal. She whispered, "Better than sex with my husband," pushing my guilt and excitement to the limit. In the end, I came on her face. Though it was just a one-night affair, I was left completely spent—yet with a memory I'd never forget.
