I went on a hot springs trip with my mistress, but since we can't meet every day, her obsession was incredibly intense. She constantly played with my cock around the clock, repeatedly fucking me nonstop. Even when I wanted to cum, she'd tease me to the edge without letting me release, and as soon as I finally ejaculated, she'd start tormenting me all over again until my dick ached and felt numb. In the end, she controlled my climax with a countdown, pushing my body to the brink of its limit. But her ass was insanely sexy, and her big, soft tits with prominent areolas drove me wild—every time we got intimate, I'd get hard immediately, drenched in sweat. Every time I got erect, she'd eagerly lure me into sex again, and from morning till night we kept going relentlessly, cumming a total of ten times over the one-night, two-day trip. Wow, seriously, she's the ultimate mistress.
