DVAJ-649 During paired practice, I got an erection from seeing a mansji and pressed the tip of my penis against her there, inserting it 1cm through her bloomers to tempt me. Unable to endure it any longer, I fully inserted it and ejaculated inside her mul

I do stretching and muscle training pair practice with the female ace of the track team, Nagarekawa-san. During close-contact training, I feel her hair's scent, the softness of her breasts, and see her pubic hair protruding from her bloomers, causing me to get an erection. I rub the tip of my penis against her vulva through her bloomers, stimulating it with 1 cm of insertion! She acts calm while continuing practice, but is she trying to tempt me into inserting it? Eventually, unable to hold back any longer, full insertion! My penis, brought to the brink of explosion by being teased with 1 cm of insertion through her bloomers, is ridden in a reverse cowgirl position on her big ass, feeling incredibly good... I find myself getting hooked on Nagarekawa-san despite her having a boyfriend.
