A library with a strange poster that says, "Please do not make any noise during lewd acts inside the building." If you make a sound inside the building, you will be warned to be quiet by the librarian and the surrounding customers. The two of us virgins, who came to this library for the first time, looked around the building and saw a big-breasted beauty having her breasts massaged by a man!? When we peeked in secretly... he opened his rock-hard erect dick!? It's inside the library, you know?? Then he inserted it right away!? A very intense adult sex has begun! But... never make a sound! Silent & slow piston sex with no sound!! Now that we finally understood the rules of this library, we boldly approached the girl next to us and asked her, and she readily agreed! Unexpected virginity loss in an unexpected place! After that, a huge orgy with men and women mixed together 9P! Even if it feels good, you can't make a sound! The girl can't even moan! No sound of intense piston action! Excitement MAX slow piston in a mysterious space! Suppressing our voices and secretly cumming explosively!! All that can be heard in the building is a faint echo of sighs and the lewd sound of squelching. I definitely can't make a sound, but... I cummed inside her many, many times! I'm sure we'll be coming to this library many times from now on...
