One day my childhood friend Ami-chan proposed that we practice having sex since she was worried about me being too much of a virgin when she got engaged... She even offered herself! We started our secret sex training sessions... Of course, once I inserted myself inside her, my morals kicked in... But then I realized that if I could just feel her pussy through her pants while rubbing against it, maybe that would be enough... Little did I know, her pussy juices were flowing out and making everything wet... And not only that, but there was something hard poking at her pussy from the outside of her pants, like my dick was still inside her! This went on until finally, we couldn't hold back any longer and gave in to our desires. It was a forbidden yet exciting experience. Our bodies became one under the thin barrier of her panties. Their touch ignited a passion within us both that wouldn't quit. As we continued our secret sex training sessions, the line between right and wrong began to blur, and all that mattered was the intense pleasure we shared together.
