I am your sister and I work as a nurse on a circumcision clinic. I have a foreskin collection. I arrive home and I see you trying to restre your foreskin, so to "help" you I show you my collection, take a dildo and play with the foreskins while I talk about how I love to waste the foreskin, and to play with it. I tell how we do the circumcision in the clinic and how tight we like to make it. At the end, I take one foreskin and stitch to your cock and give you instructions on how to proceed.
