I was the oldest c***d, and pretty much did anything I wanted. I was 2 years older than one of my sisters and 3 years older than the other one. I was ... typical 13 year old male, high sex drive and all. I would steal panties from my sisters room to rub on my cock and balls as I masterbated. I went in and got a good dirty pair one day, and thought I would go to my shed and rub one out. I could smell the musk of the panties from my pocket as I tried to sneak out the back door past my sisters. My. Sarah twirled around to give us the full view and then leaned towards Debbie and kissed her on the lips. Debbie responded immediately, kissing back and putting her hands on the back of Sarah’s head and on her waist. They kissed for a couple of minutes, exploring each other’s mouths with their tongues then broke apart. ‘Shall we go inside where it’s a little more discrete?’ We picked up our discarded clothes and drinks and followed Sarah into the living room, dropping the clothes in the doorway. "ANN, you are the parent here!" I never wanted to be a parent. I never wanted to have kids! I wish they were never born!"I couldn't control myself and violently yanked her off of my dick by her hair. I didn't say anything but I am sure the air sizzled around my head. Letting go of her hair, I took deep breathes to even out my breathing and cool my temperature. From what I understood of the effect of my controlling seed, Ann could not help but tell me the truth. I couldn't believe that she meant. I’m shaking. I stand behind her taking in the beauty of her asshole. I rub the head of my cock against the soaking wet pussy, the head now glistening. I place it at the entrance and slowly, slowly start to part the sides of her hole. All I want to do it push in with all the force I can, her ass flat against me, but I resist, this is the first time she has let me put my dick in this most secret of holes. I don’t want to fuck this up; I want her to enjoy it.“Ok, try a bit deeper, yes...good..
