"I want you to come inside me, Derek," she moaned. Her orgasm seemed to be approaching. "Will you do that? Will you come inside me?"
"Yes," I gasped, "but I want to fuck you first. Lie down on your back."
"Yes, baby, tell me what you want." She clambered off of me and lay down on the floor and spread her nylon-clad legs.
I quickly got off the sofa and positioned myself between her open legs and quickly slid inside her. From this position her huge tits somehow looked even larger.
"Oh yes, Derek," she moaned. "Fuck me, fuck me hard! Give me all that dick!"
I was in control now, and I discovered that I could go deeper than when I'd fucked her from behind. "God, you're beautiful."
"Thank you." She smiled, then her face became more earnest. "Now fuck me, slam that big dick in my pussy!"
What else was I to do?
I fucked her as hard and as fast as I could. Fucking was quite the workout, I realized. I'd started going to a gym the past two months, luckily, and was just beginning to get into good shape.
I thrust away at her until she ordered, "Grab my ankles. Pull my legs together. Lean on them and piledrive me!"
I was a little worried about hurting her in that position, but I did as she instructed. A moment later I was leaning on her strong nylon-clad legs and pounding her from this new angle.
Apparently this angle worked well, because this sweet grandma became wickedly verbal. Hearing her talk dirty made my balls boil, but I was determined to make her come before I did.
"Oh yes, Derek, pile drive my pussy! Fuck me, fuck me, don't you dare stop. Give me all that big fat grandma fucking cock! Oh yes, hammer me, drill me, pound me!"
Sweat was pouring off me in this wicked unorthodox workout. "Come for me, my sexy GILF," I growled as I hammered, drilled and pounded her pussy.
"GILF?" she gasped. Her orgasm was close.
"Grandma I'd like to fuck."
"Oh you dirty boy," she cried, "then fuck your GILF, give me all that fat cock and cum inside me."
"You first, my full-time grandma cum dump," I grunted with a smirk. Clearly I'd been reading too much erotica.
"Oh yes, Derek," she moaned, "I'll be your granny slut, your grandma cum dump and your GILF fuck toy."
Her implication that this could be more than a wild one-time thing sent a shiver through me and made my balls boil with the imminence of my explosion. "I'll cum in this granny pussy, you sexy thing," I assured. Holding back was taking every fibre of my being. "I'll cum inside my grandma slut as soon as she cums on my dick."
A few deep strokes later she gave a scream and her body shuddered against mine. "Oooooh, yes, Derek, I'll be your sluuuuuuuut!"
Only seconds later, triggered by the noises coming from her mouth, her declaration of being my slut, my own orgasm was released and I unloaded deep inside her.
"Just... fill me up," she moaned loudly.
"So good," I grunted, shooting rope after rope into her.
"So good," she agreed in a weak voice.
Both spent from our climaxes, so close together, we collapsed in a gasping heap.
After a moment I pulled out and helped her to lower her legs. Then I bent down and kissed her.
Tender and sweet.
After a long kiss, I helped her up and we sat on the sofa, still trying to catch our breath.
At last she said, "I meant what I said, Derek. Anytime you want to come over and fuck me, you're welcome to."
"I plan to take you up on that offer often," I assured her.
"You'd better," she said with a smile. "Now that you've reawakened my neglected libido I'm going to need a lot of fucking."
"And I always need it."
"I haven't felt like a woman for a long time," she whispered, resting her head on my chest.
"You're all woman," I began, when a sudden sound of the doorbell startled us both.
"Drat, who could that be?" she said, as I rose and took a careful glance out the window.
"Shit, it's my Mom!"
"Quick!" Mrs. Barnes hissed. "You'd better get dressed."
I hastily began to retrieve my clothes from where they lay scattered on the floor. "Go to your room and put something on over that outfit," I suggested, "I'll get the door."
"I suppose I should," she said with a cute giggle. "Your cum is leaking down my leg."
"There's more where that came from," I growled at her as I slipped on my sweats and hid my underwear under the sofa cushion.
Just as I was pulling on my shirt the doorbell rang again and I dashed over to open it.
"What took you so long?" Mom asked, walking in.
"I was downstairs putting a box away."
"Where's Mrs. Barnes?"
"In the washroom, I think." It was quite possible that she actually was.
Mom glanced around. "I was worried about you."
"My truck is outside, in the driveway. Where did you think I'd be?"
"You haven't been answering your phone," she said.
"Oh, uhm, maybe it's in the truck." I wasn't actually sure where it was.
"Perhaps. Anyway, why don't you see if Mrs. Barnes would like to come over for dinner today?"
"I'll ask her," I replied with a nod.
"The tree looks nice, by the way." Mom said, taking it in.
Just then I noticed a small spot of cum on the floor. "Yeah," I muttered, trying to rub it away without drawing Mom's attention. "She picked a great tree."
"Your son is an absolute gentleman." Mary's voice behind us almost made me jump.
"He sure is," Mom agreed, as we both turned around.
Mary was in sweater, pants and slippers, not even a remote trace evidence of our recent transgressions visible.
"Mom is inviting you for dinner tonight," I said.
"That would be lovely," Mary smiled warmly. "Will you have some hot chocolate now, though?"
"I'd love to, but I need to get home," Mom said with a regretful smile. "The chicken is in the oven."
"Well, I'll bring dessert," Mary said. "No, I insist," she continued over Mom's protestations, before adding with the slightest smirk in my direction, "I make a delicious homemade pie. I already have one ready that just has to be baked in the oven."
