I really don't believe them showering her with well worded compliments and making her horny. They are kids after all, it can be something more naive and almost innocent praising that may turn her on.
Can this be like a simultaneous masturbation class where Sophia and the boys are masturbating and later on Sophia helps them finish on her breasts and/or face (as per choice)... Sophia rubbing one out in front of them in all her glory would be something else....
