I am an expert at giving blowjobs

Since she started dating her current boyfriend, she has idiotized him because of his dick-sucking. She's a pretty experienced girl who constantly watches porn and is the daughter of a well known sexologist, so since she was a little girl she has heard the benefits of sex and good orgasms. Her boyfriend is a rather innocent boy, the girlfriends she has had have always been virgins and she knows very little about sexual pleasure. This girl has taught him new techniques and every time she wants to please him she asks him to drop his pants, kneels down in front of him and starts sucking his penis very hard, biting softly from time to time and passing her tongue very wet through her testicles.
