Ami - Good student

Crawling on her fours, like an obedient puppy, Ami approached her teacher. They were in his flat. Since he found that his best student is really Sailor Mercury, he started to blackmail her. First he just made her to let him grope her body, look under her skirt or caress her full breasts. But of course, it wasn't everything. After a week, he asked for a handjob and Ami did it. She was deeply embarrassed when her hand was all covered with his sticky semen, but she wasn't able to resist.
Week passed by and he invited her to his flat after the school. When they were inside, he made Ami to walk on her fours, like a dog, put a leash on her neck and sat on the sofa, looking at his slave with lust. Blue eyes of Sailor Mercury were filled with tears as she was looking at his huge cock pointed into her pretty face. She knew very well what he wanted her to do, but she was afraid of it. It was her first blowjob.
"Come here, Ami, be a good student and suck your teacher's dick. I know you can't wait to wrap your lips around my cock", said her sensei, forcing Ami to come closer. His dick was already touching her cheeks...
