Grandma’s got an itch that needs scratching

Se got up and switched off the light as I stood up to undress. This kept going through my mind during and after Sis and I cleaned up from our last session. XXX “Lets lay down and relax, I know this is a lot to take in”, she said. I looked over at Sis who was on the couch, already scantily dressed she had her knees up to her chest and feet planted apart, which drew my eyes right to her crotch. The blood felt like it drained from my body as I went numb. “YES”, I said. and I”, she said. “2 bad”, I wrote. It was feeling really good and the pressure was rising, I knew my cock was swelling in her mouth but I had control and was intent on enjoying this. I was still in disbelief as Mom was coming out of her bathroom with something in her hand, “come here, there is something you need to know”, she said.
