Grandma got dressed to go to the supermarket and I hopped in the shower. As I stood under the water, I took my cock in hand and quickly rubbed one out as I replayed the events from last night over in my head. From watching grandma in the shower to her asking me to masturbate for her, to her joining me, to the two of us coming almost at the same time, to curling up to fall asleep in her arms it all seemed surreal. "Dear Penthouse Forums." I grunted as I blew my load. Feeling somewhat satisfied now that I had taken care of that, I washed up and since it didn't look like we were going to go anywhere just threw on a t-shirt and my shorts, found a Godzilla movie marathon on TV and settled in.
Grandma Rosie came home about an hour later, and asked me to help her get the groceries out of the car. Just as we got the last bags in the house it started pouring down rain like it had the day before, we put the groceries away and I went back to the movie as grandma disappeared into her room for awhile.
The rest of the day passed without incident, I watched guys in rubber monster suits stomp on sets of Tokyo and grandma did some cleaning up, caught up on some reading and made us dinner. After dinner I was half watching an action movie in my room, when I heard the shower start up. Thinking back to last night, I turned off the TV, got up opened the bedroom door stripped off my clothes and started masturbating as I again replayed last night in my head.
Soon enough I heard the shower stop and slowed down the workout I was giving my dick. After all I wanted grandma's appreciative eyes watching me. She emerged from the bathroom and passed by my room and stopped in her tracks.
"Well, I see you got started without me." she said walking into the room and sitting on the edge of the bed.
"Couldn't be helped," I said, not bothering to stop, "He wanted attention and I gave it to him."
"Do you mind?" grandma said, and reached for my cock. She gently pushed my hand away and wrapped her hand around my cock. I thought I died and went to heaven. "I don't know about your father, but I think you've inherited your grandfather's dick."
She started slowly sliding her hand up and down my shaft, and all I could do was lay my head back and moan in pleasure. It may have been a while since my grandfather passed, but grandma Rosie still knew how to handle a cock. I reached out and pulled her robe open, and started fondling her perfect huge tits. I flicked my thumb over her stiff nipple and she moaned in appreciation, I had to shift in the bed a little to grab her other tit, and grandma also moved to make it easier for me to get both tits in my hands. She picked up the pace on my cock, and I let one of my hands drop towards her legs, I gently parted her thighs, and reached between her legs feeling the heat of her pussy as I pushed her legs further apart. She gasped as my fingers grazed her clit.
"Be gentle, Alex", she said, using her free hand to fully open her robe and expose her body to my appreciative eyes.
I lightly flicked my fingers over her clit again, getting another moan of satisfaction out of grandma as she squeezed my cock and slowly stroked up and down running her palm over the sensitive head. I tried to push a finger into her, but she grabbed my hand, "Gentle. Here, let me show you. Follow me."
She let go of my cock, stood up, took her robe off and headed down the hall to her room. I jumped out of bed and followed her, my dick leading the way, following my grandmother's perfect ass. She lay down on her bed "More room in here. Now, let me show you how to properly play with a woman's pussy."
Kneeling down on the bed next to her I followed her directions and found her clit and started gently running my finger over it, feeling it getting harder as I massaged it. Grandma reached between my legs and started stroking my cock again, which was still rock hard of course, and moaned as I continued to rub and flick my finger over her fully engorged clit.
"Now, slowly move your hand down, lower, lower, right there. Now gently, slide your finger inside me... yes... just like that... ooh, that feels good." she moaned as for the first time, I felt like I knew what I was doing. Like I said before, I'd had sex with my girlfriend Susan (we were each other's firsts), but since we were a little inexperienced there was no foreplay or buildup. We kinda got naked, I fucked her for a couple of minutes and came pretty quickly. My grandmother on the other hand, was taking her time getting me off, alternating between long slow strokes, short quick strokes, rubbing the swollen head of my cock, and gently squeezing the base of my cock to keep me on the edge.
"Now another finger," she moaned, her head tossed back and her eyes closed. At this point she was soaking wet and my second finger easily slid inside her, "Now, slowly, slide them in and out."
I did as I was told and for the next few minutes the only sound was the slight squishing sound of my fingers probing my grandmother's slit. My eyes bounced back and forth between her hand working my cock, my fingers in her pussy, my other hand massaging one of her massive tits, and the look of pleasure on her face. She opened her eyes and found me looking at her. She smiled at me and I smiled back. "You getting close sweetie?"
"Yeah," I gasped realizing that this was probably the longest I had ever gone without cumming, but not even worried about it. I wanted this to last as long as we could make it. "That feels so damn good grandma."
