Young people need to be prepared for adulthood so that they are ready to use their genitals properly and safely. Madame shows them the technique of intercourse, teaches them how to suck and swallow and demonstrates by personal example how to get an orgasm. The young men really liked the lesson - they absorb all the knowledge with genuine interest. The adult woman seems quite happy with the result. I have no doubt they will repeat the lesson on their own!
Girls like to be slim and take care of the figure. Then they get picked by guys with big phalluses and give them a cheek bump. They even enlarge their lips to make their mouth look more like a pussy. And guys get turned on by sticking their dick in those plump lips. The more and deeper the girls take in their mouths, the more they are appreciated. The black dick in the blonde's mouth looks especially cool. Aesthetically spectacular! That's why white girls sucking negroes is beautiful and spectacular!
