S1 No.1 Style presents a tall, popular, and kind senior from the volleyball club, Mitsuha Ashitaba, who unexpectedly agrees to have sex. One day, I accidentally caught a close-up view of Mitsuha changing clothes. Seeing a woman's naked body for the first time shocked me—her stunning figure and cuteness instantly captivated my heart. Ever since, I've been unable to concentrate during practice, constantly distracted by memories of that moment. I deeply appreciated her gentle, motherly concern for me. Her warm smile made me believe she'd agree to any request, and I could no longer suppress my urge to see her naked again. Gathering my courage, I asked—and to my surprise, she said yes?! Overwhelmed, I impulsively requested everything: kissing, tongue intertwining, how to touch her breasts, blowjob, pussy, and full-on sex. As a result, Mitsuha began teaching me about sex, making lewd sounds as she gave in to each request. An unbelievable, dream-like scenario unfolds right here!
