随机聊天如何变成一个全面的群交？

Mark Zebro's in the kitchen making dinner. Sebastian's online, half-dressed and bored. Then Johny pops up in the chat. As if the universe was listening, Sebastian's old uni buddy Dominik shows up at the door. Mark doesn't even know him yet. Three guys already inside. One horny newbie on the way. It started with a surprise and turned into one blazing hot afternoon. This is Buddies. You know how it goes.
