My hot shameless stepdaughter

This is so wrong, but how can I resist it when my hot 18 y.o. stepdaughter just throws herself at me stripping naked right in front of my eyes, bending over and spreading her young tempting fuck holes and dropping down on her knees to suck my dick. She does it with so much pleasure I just lose control and cum right in her mouth. Next day I eat her out right in her classroom and the day after that we start fucking and never stop until today.
