My sister wants me to purposes before the return of our parents
I fucked my sister once and it was enough to make them want more. We both had a lot of time without fuck, so we made an agreement to have sex only once and keep it secret. It was only to satisfy our desire. But my half-sister has become dependent on my cock. I understand well, it is not easy to forget once my cock enters into you. But sometimes she wants to do it when it is least convenient. Several times we were almost caught. This would have had to stop, but I am weak, and her tight pussy is very delicious, so sometimes it is hard to say no.
