One day, I got engaged to my childhood friend Ami-chan, but I'm so much of a virgin that I might get dumped... "Then... how about you practice with me?" Ami-chan, whom I had been doting on like a little sister, made an unexpected proposal! Tentatively, we began practicing sex... Of course, if it went as far as insertion, there would be moral issues... So, if I rubbed against Ami-chan's pussy through her panties... But for some reason, something is overflowing from Ami-chan's panties... Moreover, my dick has already entered her pussy through the fabric........ By now, everyone should understand. This is sex. Sex performed through 1mm of fabric in her panties. The excitement that bursts forth along with a sense of taboo. The two of us surpass reason and 1mm of fabric and ultimately combine firmly. The secret sex training that can't be stopped.
