I'd been feeling really good lately, sort-of on cloud 9. There's something about getting laid well and often that really makes a guy feel alive, y'know? Anyhow, I was hanging out in the living room playing some video games and listening to music, having a good old time, when I heard my Mom come in from the Garage and from the sound of it she was carrying some plastic bags. That meant she'd been to the store, and that meant maybe she had some potato chips or something – I'd looked for some earlier, but we were out. So I got up, magnanimously, to "help" her – mostly as an excuse to look in the bags as I unloaded them.
Peeking around the corner into the garage I saw that Mom had closed the garage door, so I didn't have to press the button and wait before heading out into the garage. I was nude, so without closing the door the old ladies across the street, and the young ladies that lived next door to them, would have seen me. Not being one to offend I'm always careful to check for this – though Dad forgets sometimes. He's always running in there for a tool or something. Anyhow, I went to the back of Mom's minivan and began unloading shopping bags. Already I'd spotted the chips (yeah!) and they were my favorite kind, too.
Mom came out of the master bedroom a second later, and I could see she'd disrobed. Mom hates clothes and if the rest of the world were as open as our family I think she'd never wear them.
"Oh," she said absently as she came into the kitchen and started to help me putting stuff away, "that damn bra was driving me crazy."
"Yeah," I joked, jibing her a little, "don'tcha just hate that?"
"Smartass," she laughed, swatting me playfully, "you can laugh, you never have to wear one."
"Oh, but I like to sometimes," I kidded, drawing a big laugh from her.
We worked quietly for a few minutes then, and I was left with only my own thoughts to converse with. Mostly, I was thinking about how to beat the next level in the video game I'd been playing. But also, as Mom moved around the kitchen I found myself admiring her, and thinking thoughts I probably shouldn't. Like, for instance, "man, how does Mom do it? Forty years old and she still looks great! Her figure is almost as good as Sis's, and she's a lot older, and has had kids..."
Then Mom bent down to put some cans away in a lower cabinet, and I got a great look at her ass and pussy, which was even pulled open a little from the position she was in. Man, I thought, what a great ass Mom has... Oh well, I thought, and went back to my work. Grabbing the bags of chips, and carefully setting one aside so Mom wouldn't notice, I reached up to put the rest in the high cupboard where they go. It just so happened that to do that I needed to get behind Mom and stretch up. No biggie.
So I got behind Mom and opened the top cupboard, and reached up to put the chips away. I guess I forgot to tell Mom though, because just as I was leaning in, she backed out a little bit. It wasn't much, but it was enough. I felt the head of my cock slip right in to something really tight and warm.
"Whoooeeee!" Mom yelped, high pitched and loud. Then she tried to stand up, and wound up banging her head on the bottom of the countertop. "OW! Shit," she yelled, and in an involuntary movement caused by the pain in the back of her head, she inadvertently backed up more. I felt another inch of my cock push in, and realized I was in my Mom!
"Huh?" I said aloud, looking down in shock to see my cock sticking about an inch and a half into my Mom's asshole. "Oh fuck," I yelled, and quickly stepped back, yanking my cock out of Mom's ass right away. "Jesus, Mom," I said, truly regretful I'd violated her, "I'm so sorry! I didn't mean to – I mean, I... I didn't even know I was hard!"
"That's OK, honey," Mom said, rubbing the back of her head with one hand and holding her ass cheek with the other, "just help me up, alright?"
"Yeah, sure," I agreed and immediately helped Mom to her feet, then stood there looking down at my own, feeling awful. But I could also see that my consternation was having no effect on my erection, which still stood out hard as hell straight from my middle, as though defiant. I could also see a little brown from Mom's ass on it, which should have grossed me out, but it didn't. In fact, seeing proof I really had put my cockhead in my Mom's ass, even by accident, kinda turned me on, and if anything I stiffened up some more.
Seeing my shamefaced look Mom laughed and poo-pooed the situation (no pun intended). "Sweetheart, relax," she said, lifting my chin with her finger, "It's OK, you just caught me by surprise, that's all. I know you didn't mean to do it. Actually, I'm surprised it's taken this long for something like that to happen around here the way your Dad and You are always letting your little heads lead the way for the rest of you..."
"Yeah," I countered, relaxing enough to laugh stiffly, "how can we help it when you and Sis are always running around with your headlights on all the time, and little else?"
