She said ” well, don’t worry, I will take care of you in a moment ” then she kissed my cock and I went to take bath. I didn’t close the door (...I wanted her to see me)She came and watched for 5 minutes and seeing that my cock was still erect, she said, ” need a hand with that rock hard dick? “, I said, “well, I would prefer more than your hand “. She then came inside and kneeled down and put my dick in her mouth. Wow, I cannot describe the way it felt. Amazing. Oh, well, did I describe her lips?. Granma began stroking my cock to full stiffness while I fingered her shaven pussy and sucked on her pierced nipple. Meanwhile grandpa had Mary facing the rocks as he rubbed her holes from behind. No one was around as we played, once I was hard granma jumped up putting her legs around my hips again, “now fuck me and fill me with the juice of your loins” I felt granma’s cunt envelope my shaft and she began to bob up and down water splashing up. I went back up to the head and went down trying to engulf his entire cock, I choked. I continued sucking his cock and he put his hand on my head and started shoving his cock in my mouth. Gagging me over and over. Rick stood up and told me to take off my dress. I took it off and he shoved his cock right back in my mouth. Standing over me he was face fucking me bad, gagging me constantly, I could feel my spit dripping off my chin all over my chest. Rick said you’re a good little bitch aren’t. I knew it, and I knew that if I didn't answer ... if I didn't move it was giving him permission to go on. I didn't move a muscle, I just stared back.He focused back on my pussy and moved his face closer, maybe an inch away. I saw his tongue come out and lick his dry lips, I felt his hot breath on my tender skin. I tensed ready for the swipe of wetness I was so eagerly waiting for."Alright guys, we need to move on with it or we're going to run out of time," Tim's voice came through the door.
