SONE-925 | I was just playing around with my serious childhood friend and trying to play SM... but she awakened to her true masochistic tendencies and became a submissive, sensitive masochistic pet - Mita Marin

My childhood friend, Marin, who is one year older than me, had excellent grades and often came over to my house to get help with my studies. I recently became interested in SM play, so I told her about it, and she asked if I wanted to try it... Yay! First, we played with bondage using cotton rope. I tied her up in an embarrassing position, and she already had a stain on her panties... When I started teasing her with a brush, her erotic fluids started to flow. I got excited too, so I couldn't help but stick my dick in her mouth! Is this what they call deep throating? It looks so painful! So exciting! It seemed like my sister wasn't completely opposed. Is this what they call a masochistic awakening? I might have some talent.

...I decided to train her as a masochistic pet.
