Hina, Sanae Momoi and Uta Kohaku are considered to be grown up women from the moment they have turned 20, so their friends decided to make a little celebration to that name and give them a few very good lessons they will need in life. Girls were dressed up in festive kimonos and eager to start exploring the life of a grown- up person. Their first lesson was about blowjobs. For start, they were supposed to get down on their knees and gently touch balls while licking dicks with their moistened tongues. Girls liked it as well as their partners and soon it got so hot in the room that guys could not hold back anymore, so they came straight in those dirty mouth.
