Catch half-sister watching porn and piss her off

She knew her stepsister needed a good cock because the other day she caught her watching porn on her laptop. she found some excuses, explained that she was looking for I don't know what, but come on, it didn't fit, and little by little he took advantage of the shame he was in to take advantage of her and give her what she needed, his hard cock, that she accepted it as if it would repay him the favor of saying nothing to anyone. total, that her stepsister gave her a dick and you can't see how much she liked it, much better than watching porn. but you, if you don't have any stepsisters like that around, keep watching, huh.
