Porno hostel

Roberta Farnese notices a lot of movement of young people entering a doorway, intrigued (and excited) she sneaks into the first open room and finds two students and a professor giving a urology lesson, behind a door, after having listened carefully to a lesson on erectile dysfunction, she decides to convince all three that erectile dysfunction does not exist... With the usual Farnese method she begins to give them all a good blowjob, then after a lesson on applied physiology she makes them all cum.
