After drinking together the night before, I cheat on my partner with my junior coworker Mio even though she has a partner too. On Sunday morning, her beautiful sleeping face, smooth pale skin, faintly visible nipples, lingerie-framed ass, and soft mound through her panties make my morning erection impossible to ignore. I slide inside as she wakes, then fuck her once, twice, and three times. Mio is already oversensitive from the night before, but our perfect chemistry keeps driving her to orgasm. We cancel our plans and continue the illicit sex until sunset.
