Blackmailed Grandmother Ch. 2bySam Jason©
I again increased the pressure from my legs, grinding that little pleasure center with force it had never be fore experienced.
"Oooooooohhhhhh!" she groaned loudly. And then, as I increased my pace, she looked to the ceiling and tensed her whole body until it wasn't moving at all except for an intense internal vibration.
I pressed my knees up against then with all my might and thrust and thrust again.
A long cry escaped her now, "Aggggghhhhhh! Noooooooooo! You're making me... making me... Aaaah! Aaaaah! I'm cumming! Billy! BILLY! I'M CUMMING! AAAAAHHHHHHGGG..."
The rest was just an explosion of air from her. Forty years of locked-up lust was being let out of my own Grandmother... and my penis was the key.
I couldn't believe it: my own Grandmother was on top of me, and I was giving her the first orgasm of her life. Perspiration glistened on her and rolled off onto me in a rain.
She remained at the top of the mountain of pleasure for a good 45 seconds. That's when I felt the volcano in my balls decide to erupt.
"Ooohh!" I groaned, "I'm gonna cum!"
I was surprised to hear my Grandmother say, "Billy, no; I can't have your "seed" in me; we can't mate; I'm your Grandmother... that's incest!
With that I just let go and stream after stream of hot, white cum washed over every square inch of my Grand mother's womb. Gobs of it; I'm sure more than I had ever spewed forth in my life.
"Aaaaaagggghhhh!" I howled.
And a strange thing happened. When my Grandmother felt the hot river of my cum gush inside of her, some per verse or obscene taboo must have burst inside of her:
"Oooohh, noooo.... ahhhhhhggggggg... aaaahhhhggggg... again... again... AGAIN! I'M CUMMING! MMMMMMAAAA...!
I had tilted the bureau mirror so I could see all the action from another angle. See, I plan ahead. Now my eyes caught sight of my Grandmother's buttocks hunching and squeezing tight as she drove herself onto my cock. I realized my Grandmother was furiously fucking me... fucking me on her own, her untanned ass a blur.
Again my Grandmother had achieved a tremendous orgasm. This one triggered by the feeling and the thought of accepting her Grandson's sperm deep inside herself.
It continued for another minute... the pleasure we both were feeling, and then she collapsed on top of me.
I must have fallen asleep for a while. When I awoke, my shrunken penis was still inside of the beautiful, sweaty woman on top of me.
I looked at the corner, and could make out a tiny red light: my video camera had been placed perfectly. I was really going to enjoy watching that lovemaking session. And... I might find another use for it someday.
I glanced at the clock. Well, well; I missed my train home. Home. I didn't even want to think of it right now, not with my bitchy Mother waiting.
"Wait a minute," I thought. "I bet the IRS would be very interested in the "extra set" of books my Mother kept." I bet she'd do anything not to have that happen ... anything! Maybe "Billy Blackmail" was going to ride again.
My Grandmother was sleeping soundly, but the thought of my new scheme, the thought of fucking my own Mother, had brought my penis back to life. I was fully hard again.
My Grandmother awoke then, looked at me, and a look of disbelief filled her eyes.
"Oh, no!" she whispered. "This wasn't a dream!"
I reached up, brought her lips to mine for our first kiss. She struggled a brief moment, and then my tongue entered her mouth.
I put my arms around her, and rolled so that I ended up on top of her. She gasped when my mouth left hers.
I started a slow pumping of my cock in and out of this wonderfully sexy 65 year old. She pushed feebly at my chest with her hands and then I felt her feet brush up my legs, then my thighs. Those feet finally intertwined at the top of my buttocks, her long, tan legs surrounding me. This flowered her vagina open fully to me and she instinctively offered her clitoris at just the right angle.
"Oh, please, Billy... I'm begging you... harder...."
