You get up and walk to your own bed and go back to sleep, slowly digesting Jessie. When you wake up, all that's left of her is some pudge on your gut. As you were getting up you felt nature's call, and went into Jesse's room. You took a number of her panties, removed your pants and underwear, and relieved yourself on her bed. She went out just as she went in easily. When you were done shitting out your sister, you whipped yourself with her panties, throwing the soiled ones in the pile.
