She exercises and sucks her brother at the same time
The girl insists on getting in shape, even though she doesn’t really need it. You can say that she doesn’t lack or have more than anything, but she insists on doing it and when a little bitch like her insists on doing something, there is no one who wants or can stop her. He even exercises while sucking his own brother’s cock. Who after a while, can’t stand the urge and also wants to penetrate her pussy. For her it’s like doing a little leg workout while she’s riding his cock, but for him it’s so he can cum and give himself the pleasure of nailing the young girl. That anyone would want.
