I hardly slept the night after I had fucked 'Grandma'. I would like to say that guilt was what kept me awake -- it wasn't. The reason I couldn't sleep was that I wanted more. As sick as I knew it was I couldn't help but be excited. I would fall asleep for a little while and then wake up.
I beat off twice during the night but it never calmed me down enough to stay asleep. I couldn't wait for the next morning. As soon as my daughter left for school I was going to find out if 'Grandma' or Murine was around and if it was Murine I was going to fuck her and fuck her hard.
Even though I struggled all night with how I could have done what I did to 'Grandma' as soon as my daughter was off for school I stripped off my clothes and went into the guest bedroom where Murine was sleeping.
I pulled the covers off of her and stood there watching her nightgown rise and fall as she took the deep breaths of sleep. Her large breasts seemed to stretch the material of the gown making my hard-on grow even harder as I stood over her.
One wonderful thing about my wife's family was the women had large breasts. I had been around long enough to know that they started out with sizeable tits and then would balloon after pregnancy. I remember years ago how I couldn't wait to see if my wife followed suit.
She did.
I climbed on the bed next to 'Grandma' and moved very close. I pawed her big tits which only served to fuel my desire to spear my dick into her depths. In my state I wasn't thinking clearly and before I realized what I was doing I grabbed the collar of her gown with both hands and pulled ripping the gown and freeing those big tits.
"Shit," I said out loud.
My mouth was on her left nipple instantly. It hardened as my tongue went to work. I could hear her breathing change and I knew she would wake soon.
I didn't want to give her the chance to wake up and stop this before I had a chance to feel her warm wet pussy around me. If she were her normal self when she awoke I would just have to hold her down. While I kept sucking on her tits I positioned myself over her rubbed the head of my dick up and down her entrance a few times and then shoved it right up her cunt.
I stopped only because my pelvis met hers.
Her eyes flew open.
"Fuck!" she yelled.
My heart raced was she 'Grandma' or Murine?
"George, you're an animal," she said looking up at me and bucking her hips back to meet my thrusts.
I could have exploded right there. She was just who I was hoping for. I leaned down into her and kissed her full on the mouth my tongue penetrating her lips. Her tongue met mine and they danced. It was like we were trying to suck the life out of one another.
Pulling away from her kiss I told her, "you are the hottest piece of ass I have ever had."
I meant it. She wasn't the prettiest, her body wasn't the greatest but she had a love of dick and it showed.
Murine reached up and grabbed my head, looked me right in the eyes and said, "Fuck me! Fuck me and don't stop until I pass out or die!" Then she pulled my head to hers and resumed the kiss.
I was going to obey that order and I began thrusting faster. We were fucking so hard that we weren't just rocking the bed we were bouncing off of it. The headboard was slamming into the wall. The force was such that at some point the crowning piece of the headboard broke off but I didn't care. All I wanted then was to fuck Murine, who just got more excited and wet the harder I fucked into her, with every ounce of strength I had. She really was a grade 'A' slut.
I was so far gone I couldn't even tell you if she ever came. I was in a completely animalistic state at that point and didn't even know that my own orgasm had started until I heard myself grunting as my body locked up on a forward thrust. I didn't shoot ropes. I just came all in one long stream it was the strangest feeling like I was pouring my essence into her.
My arms gave way and I just collapsed on her. My face was planted on her big sweaty right breast and it felt great. One big soft pillow made just for me that breast was.
"Your breasts are magnificent," I said talking into her breast between ragged breaths.
