Svärmor lär sin styvdotter pojkvän hur man sperma inuti hennes röv och över hennes skor

As a mother I have the responsibility of teaching my daughter's boyfriend to fuck well. Above all I need to taste his dick and see that he is a clean boy. I also need to see how far his cock can fit in my ass. And above all, I need to know how he tastes his cum after he was in my ass.
