Yes, a do-over

Obeying your big sister you reach down and guide your cock into her incredible pussy. You had never felt a girl more wet and ready in your life!

Both of you sigh as you bury yourself in her. She sits up and arches her back, looking up to the ceiling. Her incredible body on full display for you. This was Fiona at her full glory. Her monster member was harder than you had ever seen it.

You place your hand on her hips then guide them up her slender waist and on to her huge hanging tits. She wasn't moving yet, just enjoying the feeling of your hands and of you inside her. You savor this perfect moment.

After a short time she finally looks down at you. Her gaze was now one of lust instead of cruelty. "Now...FUCK ME!"
