Outside of your sister

You pull yourself out of your sister. Cumming up and all over her stomach, leaving a trail from her breasts to her pussy. She shakes with her own orgasm underneath you as you spend yourself onto her belly.

After you are done, you pant and watch as she collects the semen off her belly and into her waiting mouth.

"You taste so good big brother," she says, licking you off of her fingers.

"I hope we can do this again soon" she smiles as she begins to fall asleep.

You get dressed and begin to plan the next move of your day.
