Heather still has the hots for you

You get some coffee and cereal and catch up on your email while you eat. The house is quiet.

After breakfast, you grab some clean clothes and go into the bathroom for a shower. You shave while you run the shower to get the water warm. Then you get into the shower and get your hair wet.

You feel a draft and hear the door click shut.

The shower curtain opens, and Heather steps in, naked. She is definitely turned on, because her nipples are hard bumps on the tips of her gorgeous breasts.

"I didn't plan last night, but I'm not sorry it happened. You felt so good inside me, I want you again. Are you okay with this? Not too weird for you to fuck your sister?" Heather looks up at you with big eyes and a cute little pout.
