I decided to drop by my neighbor Amakawa's house to get her to teach me some exercises. She's an active instructor, so she changes into a high-cut competitive swimsuit and starts exercising... and of course, my crotch is erect. Amakawa is very interested in my bulging cock, so she suddenly takes it into her mouth and ejaculates in her mouth. But my cock still remains erect. Seeing this, Amakawa makes me insert it raw in a cowgirl position, and even makes me cum inside her...
