On a hot spring trip, I reunite with my lustful mistress, Tsukasa, in our inn room. She's insatiable, always eager for sex, and the moment we arrive, she openly expresses her desire. In the room, we repeatedly have intense sex—after one, then two orgasms, I forget all about my wife, increasingly drawn into her allure. She asks me, "It feels better than sex with your wife, doesn't it?" Her words excite me, and I find my heart and mind completely captivated by her face and body. Sex with my mistress Tsukasa always brings ultimate satisfaction, completely enslaving me to her.
