That's ture, but you have to remember they're at a party, things like having sex on someone else's bed is normal when a crowd of young, horny, selfish, slightly uneducated people get together at a party. It happens all the time these days, truly its slightly gross but it kinda makes the Managa more realistic
I personally have never liked anyone on my bed unless I gave them permission to even sit on it. That being said its gross that they had sex on someone else's bed especially for their first time together.
