Sefure no Senpai THE ANIMATION

Yuuma arrives at his university's freshman welcome party with high hopes of making a memorable debut and perhaps finding a romantic connection. His expectations are quickly exceeded when Nana, an older student renowned for her immense popularity among the attendees, singles him out. To his astonishment, she reveals that she is actively searching for a casual partner and boldly asks to accompany him back to his residence. Overwhelmed by the sudden attention from such a sought-after upperclassman, Yuuma can hardly believe his luck as they travel together to his home. The moment they step through the front door, however, any lingering doubts vanish. Nana immediately takes the initiative, gently stroking his arousal before he can even process the situation. Caught entirely off guard and deeply confused by her forwardness, Yuuma finds himself unable to resist. He simply surrenders to her lead, allowing her to do exactly as she pleases, which ultimately results in him losing his virginity in a whirlwind encounter he never saw coming.
