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.
In this version the lady was very lucky - she met a very temperamental and persistent man - he fucked her long and gentle enough! And quite safely - with a condom. Apparently the man likes such thin women. But the lady didn't have time to show her abilities as a masseuse - neither on a man's body, nor on his cock! Maybe she is not a masseuse, but a lady on call?
What I don't get is, who's the dude sleeping on the couch next to her while daddy's banging his daughter? Her brother? Husband, maybe? He didn't even lift a finger during the whole thing. Or maybe he just squinted and jerked off quietly?
