He catches her masturbating and surprises her like this
The girl was touching her pussy in a moment of intimacy thinking that no one would be able to see her. But she was wrong, her brother is around and after seeing her masturbating, what he did was take out his cock and put it on the headboard of the sofa. When she turned around and saw his cock, she soon covered herself so he wouldn’t see her, but it was evidently too late for that. He sat next to her, and started spanking her pretty ass. But yes, soon he was taking off her panties to touch her wet and hot pussy. It was obvious that they were both very horny, so it was a matter of time before the slut was looking for his cock to suck it.
While she showed him her small tits, she took off what little clothing she had left to undress, and what she did was sit on her brother’s cock so he could put it in her tight young pussy. They both fucked until the end. After that, the other day they talked about what had happened, they both laughed about it, although deep down they wanted to repeat it.
