She lets her brother’s friend grope her ass
He’s outside in the yard, where he likes to be. There she can always see people and most importantly: people can see her. Which is what he needs so that he can then do his tricks and take him to bed. Something that doesn’t cost him much because he has a good body. And her brother’s friend can see it since she lets him grope her ass. Then he gives her a blowjob and when he has it firm, he can start fucking her pussy. At that moment, he realizes the skill the vixen has and how much she likes riding a male. It’s a fact.
