Not getting an answer, your girlfriend quickly took initiative. She urged one of her sisters closer, and told her to bend over right in front of you - your gf's face hugging her sistrers ass, she said: 
"My youngest sister has the tightest pussy out of all of us, just look how sexy that ass looks! So get that cock out and get to work ~ I wanna see her positively gaping!". 
Meanwhile the other sister came back from cleaning the grill and called "I'm calling dibs on the next!", which swiftly prompted girls calling dibs on further rounds all the way to 12th, since each girl 
wanted to fuck you at least 3 times...
This is gonna be a long visit...
