The girl climbed out of the pool and saw her friend. After fondling her pussy she made it clear that she wanted to see his cock again. There was no need to ask this black man twice - he responded to such requests at once. Her motives are understandable - such a prick is not lying on the road. And she does it with honor - her slit quickly adjusts to his size. Apparently he developed her well.
A deep blowjob is for aficionados. I liked the second part better, where the muscular guy rhythmically and deeply penetrated her pussy, so that she cummed.
