Those who think it's not normal, think about it, these are strangers to each other. That's why there's nothing wrong with it. Two adults of different sexes are at home alone, hormones are splashing in both of them. So the skinny blonde was not at all against caresses from her stepbrother, she only broke down for show, but with his insistence his brother showed the seriousness of his intentions, and that this will not go beyond their bedroom. Both are happy at the end!
Well, judging by the way everything happens, the girl has long dreamed of such sex and I think it's not for nothing she decided to pay in this way, there is either a lack of satisfaction in terms of sex or just experience is already there. Overall, he fucks her perfectly, she really likes it, judging by the moans and sighs, and the time has exceeded all her expectations, most likely he will appear in her bed more than once.
