An instructor should develop the abilities of his female students, notice their inclinations and act in that direction. And this maiden was best at playing the leather flute. This ability will benefit her a lot, not only in her studies, but also in everyday life. The main thing is daily rehearsals and on different flutes.
Any chick loves it when her pussy is licked. And this brunette found a loose tongue from her brother. Naturally, for such services she had to pay the full price - to take in her mouth and let her slit put on his dick. I can only see that she enjoyed it. And to feel like an actress being filmed and licking at the sight of her vagina and cum on her lips - she just enjoys it.
