You and your step-mom, Anna have a very special relationship. You know she likes you better than your step-sister. It's because you make her happy. Your step-mom has sent your step-sister out so you can have some special time. Summer comes back early and barges in on you and step-Mommy. You think step-Mommy is going to go mad, but both of you are extremely shocked at whats coming out of Summer's mouth. She wants to learn? She wants to please you Bro? She is a sweet step-sister, maybe you should oblige? Taking her virginity would be better than some dumb guy? Especially with step-Mom there what could go wrong, she always makes you feel good so why should your step-sister be in different. Plus, step-mommy will make sure Summer is on protection right?
