A pretty Russian student named Katty West studied penises, and today she will have a practical lesson with her teacher and two guys who will help the brunette with her studies. The teacher asks to get the guys' cocks and lift them up, because then the most interesting thing will follow. After the student picked up the girls' pussies, she began to suck them off greedily. At that moment, the teacher also dumped his penis in front of a thin girl, whose mouth was enough for everyone. Next, the guys took turns fucking the slut in her pussy and mouth, and in the end they just filled her with their sperm.
