She uses you to wash underneath her foreskin

Original Author: mazomune

As you were lying stuck to her balls with the lather from the soap, Kim turns her attention back to the huge, now semi-hard cock that was casting a shadow over her little brother. Completely oblivious to your presence, she moved her hand back to her shaft, taking you with it, back on the same long journey up the smooth dick that feels like it's 25 feet long. This time, instead of repeatedly rubbing her hand up and down the shaft, she focuses on the tip, slowly drawing back the foreskin that had recovered her cockhead.

The smell of her exposed head now that you were up close and personal with it is completely overwhelming and you feel as if you're about to faint from the powerful odor. Completely oblivious to your presence she presses your whole body, face first, deep into her foreskin. Once again you feel as if you'll lose consciousness from the strength of the smell as she slowly rubs you all around the inside of her sensitive cockhead, audibly moaning from the sensation. You soon find yourself covered in a thick, sticky substance coming from her dick.
