My sister who lives under one roof has a well-developed buttocks. Nothing could make me happier. Therefore, since she was a little girl, my brother (you) has been giving this big ass a gifted education with great care and attention. My sister gives her all to the ass training we do every day, without questioning anything. Please support my sister's training with all your might, who also uses a cock to make her aware of her body axis, and wants to make the best buttocks by rocking and rubbing them.
