I Fucked My Granny

My name's John. I'm fifteen year old. During the summer holidays, I stayed with my seventy-seven-year-old grandmother. Gran is quite short and slim, and still quite an attractive lady.
She suggested we spent the afternoon in the garden. She was wearing a white sundress which revealed her still-firm breasts.
As we sat under the shade of an oak tree, sipping lemonade. Suddenly, Gran said, "You know, John," she said, "I was quite a slut when I was young."
Surprised, I said, "Really, Gran?"
"Yes," she whispered, "My first fuck was with an uncle”. She paused, taking a sip of her lemonade. "One afternoon," she continued, "we fucked here, in the garden."
Suddenly, she unhooked her bra. Her breasts were surprisingly pert and soft. "Feel them, John," she said, "They're not what they used to be, but they’re still very nice to suck."
Her words surprised me. I looked at her now-exposed nipples, which were small and pink.
"Go ahead, John," she urged, her hand guiding my head towards her breasts.
With trembling hands, I reached out and cupped her breasts. I took one of her nipples between my lips.
Gran's let out a soft moan. Her hand slid down to my lap, unzipped my shorts and took hold of my cock. She began to pump my cock up and down with surprising expertise. I could feel my orgasm building, the pressure growing with every second that passed.
As I kneaded Gran's breasts, her grip on my cock grew firmer, her strokes faster. I felt my balls tighten, and I knew that I was close.
"John," she murmured, "Do you know what it feels like to make a woman cum?"
I nodded, unsure of what to say, and she leaned back, spreading her legs slightly.
"Let me show you," she whispered, guiding my hand to her pussy.
Her skin was hot and damp, and I felt the soft fur of her pubic hair brushing against my knuckles. My thumb found her clit, and I began to rub it in slow circles.
Gran’s grip tightening as I worked her clit. I could feel her getting wetter with every stroke.
My thumb danced over her clit, feeling it swell beneath my touch. Her breathing grew heavier, and her strokes on my cock grew erratic. I knew she was close to cumming.
"Faster," she breathed, her hand tightening around my cock.
My thumb moved with increased urgency over her clit, and she arched her back, pushing her breasts upwards.
"John," she gasped, her voice ragged with desire. "I'm going to cum."
I increased the speed and pressure of my thumb on her clit, feeling her entire body tense up. Her hand on my cock grew frantic, her strokes faster, more urgent.
"John," she gasped, "I'm going to cum."
Her words were like a bolt of lightning through my body. I focused all my attention on her clit, rubbing it in tight, quick circles.
Her breathing grew louder, more erratic. "John," she moaned, "I'm...I'm cumming."
Her hand convulsed around my cock, sending waves of pleasure coursing through me. Her pussy quivered beneath my hand, her juices coating my thumb and forefinger. She continued to pump my cock, the sensations she was giving me becoming more intense with every second.
"Do it, John," she whispered. "Cum for your granny."
I lost all control. My cock throbbed in her hand, and I exploded. As the last of my orgasm pulsed through me, I collapsed against her, my chest heaving with each breath.
That evening, I found Gran in the kitchen. She was wearing a silky, red robe that barely concealed her naked body beneath.
"Dinner will be ready soon," she said.
After dinner, I went to my room. As I lay in bed, thinking about the events of the afternoon. The feel of Gran's soft breasts, the sweetness of her voice, the way her hand had felt around my cock - it was all so new, so thrilling.
As the night grew darker and the house grew quiet, I heard a soft knock at my door. My heart skipped a beat.
It was Gran, wearing nothing but her silky red robe. She looked at me pleadingly. "John," she said, "I couldn't sleep. Can I in bed with you?"
I nodded, not knowing what to say.
She let the robe slip from her shoulders, revealing her naked body. "John," she said, "Will you fuck your granny?" Her skin slightly wrinkled with age, but she was still fuckable.
I nodded, my cock already hard.
Gran lay on the bed with her legs wide apart. She reached down and grabbed my cock, guiding it to her grey-haired c**t . With one swift motion, I pushed inside her. Her c**t walls tightened around me, and she began to moan. Her moans grew louder as she approached orgasm. Her climax seemed to last forever. "Fuck me, John," she gasped, "I want to feel you cum inside me."
My body tensed as I felt the beginnings of a cum. My cock felt like it was on fire. With one final, powerful thrust, I let go. My cock pulsed inside her, sending wave after wave of hot, sticky spunk into her c**t.
For the remainder of the summer, we fucked three or four times a day. We also had a lot of oral sex, and Gran always swallowed my spunk as it hit the back of her throat.
