Now that the three of them are alone, the idiot decides to introduce himself first.
He has his arm around his girl, pulling her closer to him while also showing his boldness by having his hand on her breast and fondling it.
The girl couldn't do anything and accept his physical advances, as this is not the first time. He has done this to her many times, and she has gotten used to it. This is nothing compared to other things she has done for him.
She had once sucked him off right in front of his friends while they were drinking and doing drugs. The only reason she was not greatly affected by it was because she was not the only one there. All his friends also had their own women humping up and down their cocks. She had it easy, as she only gave him a blowjob. Some of the other women were even being passed around like objects.
