Grandma was a very attractive lady. She kept her hair dyed blonde and usually wore lipstick and makeup. She definitely didn't look like the typical 70 year old female. She went to the gym regularly and also swam. I always thought of her as a cute little old lady.
By family tradition, I spent part of every summer at her home to do chores and run errands for her. I figured this year would be the last time, because I was heading off to an out of state college. I was torn between missing Grandma and looking forward to dorm life, imagining how much coed pussy I was going to get. Little did I know.
I arrived at Grandma's place around noon. She answered the door bell and acted like she was surprised to see me. Maybe she had forgotten that today was the day. While she was surprised, I was in shock. Grandma was wearing a black, one piece bathing suit. Her hair-blonde of course-was swept back over her head. She was also wearing her ruby red lipstick. Despite my best efforts, I was getting an involuntary chubby.
"Oh Brian. I didn't expect you. I was just getting into the pool," she said.
I struggled to maintain my composure. "Yeah, Grandma, don't you remember we said the 19th?"
"Well, welcome, come on in," she replied. She seemed to glance downward at the tent developing that was developing in my jeans, but made no remark.
I carried my bags into the hall and set them down. We hugged. I couldn't hide my erection. She must have been aware of what was happening to me, because she looked in my face and said "It's okay, Brian, it's normal for boys your age."
I still felt compelled to apologize, but the words wouldn't come out. As I mumbled and stumbled verbally, she laughed and said "Nothing to feel bad about. It's actually sort of flattering."
She excused herself and retrieved a robe from her bedroom upstairs. When she came back, we sat on the living room couch and made small talk; at least she did. I couldn't concentrate on the conversation. I kept glancing at the cleavage peeking out from her robe. The wrinkles on her neck and at the top of her breasts only served to make me feel weirder.
After dinner, she pecked me on the lips and said goodnight. She had done this a million times since I was a kid. But this time, it made me shiver. I got erect again. She felt it when she hugged me and said "Damn. Doesn't that thing ever go down?" Then she went to her room.
I was surprised that she seemed pleased instead of repulsed that her own grandson was hard for her. It confused me. As I laid on the bed, my mind began to focus on the sight of Grandma in her bathing suit. I couldn't believe how sexy she had looked. My dick sprang to attention. I was soon so hard I started to ache. There was only one way to take care of it (without my mother killing me, that is). I pulled it from my shorts and stroked it slowly. Being the horny teenager that I was, I felt no guilt about fantasizing sexually about her. The thought that she was my grandmother turned me on even more. I had jerked off to the thought of other females when I was an adolescent, including her, but those were the involuntary mental images that are part of puberty. This was different. I muttered to myself, "Grandma, fuck me. Suck my dick. I want to come inside of that gray haired pussy." The image of my dick sliding in and out of her (what must have been) salt and pepper pubic hair was the last straw. An orgasm came over me that was so deep and profound, it started in my anus. My dick convulsed so many times (I wasn't exactly in the frame of mind to do math at the time) that I ended up crying out as though I was in pain.
As I laid there in ecstasy, I was pleased with myself. As far as I was concerned, I had just had a fantasy about a beautiful older woman. That it was about my gran made me feel calm and satisfied. I soon figured I better find something to wash my jism off the sheets. However, as I stood up in my come-soaked shorts, who would walk in the room but Grandma! She apparently heard my shout and was checking to see if I was all right.
She opened her mouth to say something-then her eyes went to my shorts. She exclaimed, "Oh my," and went back to her room. "Okay," I thought to myself, "NOW I feel ashamed."
The next morning we ate breakfast together in silence. She cleared her throat and said, "Brian, I think we need to talk about last night. There's nothing for you to be embarrased about. As I said last night, it's normal at your age."
I looked up at her. "Grandma, I think you'd feel different if I told you what I thought last night."
"Brian, you know you can tell me anything."
"Well, I said slowly, "I was thinking about an older woman. She's petite, has blonde hair and"-I hesitated-"she was wearing a black bathing suit last evening."
Grandma just stared at me. "My old carcass got you that excited?"
"Grandma, to be honest, I used to think about you that way when I was 14. Seeing you in that bathing suit just did something to me."
