Stepmom wants to go swimming but has sex with her stepson instead

Hi sweetie, it's your first day of summer! I am so proud of you. You graduated this year and I have a great day planned for us.

We can go swimming! I got my bathing suit on under my clothes. It'll be like summer camp day. You used to love summer camp, remember?

I don't want to today, Stepmom. I just want to... I don't want to go swimming.

We could do archery. I've got a picnic planned.

No, I don't want to go outside. I just want to hang out here. Maybe play some games or watch TV or something.
