My girlfriend and her three best friends came to my house after missing the last train! The girls got so excited while drinking that they all ended up sleeping together... I secretly pulled down my best friend's pants and inserted my erect penis very slowly! Of course, he woke up, but I threatened him, saying, "If you find out, you'll be in big trouble," and started a silent, super slow piston! Just silently repeating super slow pistons! And then I came inside him! I raped my best friends one after the other with super slow pistons!
