My Stepmom and Sister Sex erotica stories – Y2Stories

After a few years overseas, I came home to a horny sister and a Stepmom needing both some fun of her own and to “protect” her daughter…

I had been overseas for about 3 or so years, and finally got to come home.
When I left, my sister was only 10… She used to give me hand jobs, and now was “all grown up”…
My second day back, we were up early… I’m not sure why she was, but I was still on “foreign time”…
We were watching TV and chatting. I was in the armchair, I had on my lounge pants and a T-shirt. She was on the couch in her pajamas (a very lose fitting short and a tank top)…
I’m sitting there, and I look over to see her with her legs spread, literally showing off the fact she had no underwear on.
I was instantly hard, thinking back to all the fun we had years ago, when we’d play what we called “a tickle fight”.
Basically, I’d rub her pussy, she’d give me a hand job. She was, at the ripe old age of 10, still a little young for a full on orgasm and wasn’t ready for any real penetration.
Especially from my very thick dick.
While I’m only about average in length, my girth is “exceptional”… According to the ladies. I wouldn’t know, I don’t spend a lot of time looking at other guys’ dicks.
Anyway.
So, she is now 13, and, as I said, sitting in a way as to show off her goods… and as I noticed her, she notices I’ve got a boner, and she smiles and asks if we should have a tickle fight.
I wasn’t sure she’d remember it, but totally glad she did…
I said sure and went over to sit next to her on the couch.
She proceeded to pull my dick out and I put my hand down her shorts…
She was jerking me off and I was rubbing her clit, and it wasn’t long until she climaxed… As she reached her peak, she told me to put my finger in, so I did, fingering her for her second orgasm…
About that time, I blew my load. I shot several thick gooey ropes of cum across the room…
My sister had wide eyes, saying, I don’t remember there being that much!
I said, that’s ok, I never got to finger you, but now I am!
We laughed and sat and enjoyed the afterglow of our renewed activities.
About a half hour later, I got hard again, an was thinking I’d like to fuck my sister… So I said, Let’s try something else. And I got on the floor, got up between her legs, pulled her shorts over to the side, and proceeded to eat her pussy.
I’m telling you, there is nothing more tasty than a sister’s pussy.
As I’m licking and sucking her, I noticed my stepmom standing down the hallway…
I thought oh, fuck, I’m going to jail.
But I noticed she had pulled up her nightshirt and had her hand in her panties, fingering herself as she watched me eat her daughter…
My plan was to move up my sister’s body, after another orgasm, and suck her tits, then fuck the shit out of that 13 year old pussy… But, I wasn’t sure what my stepmom would do, and after my sister climaxed, my stepmom disappeared down the hallway…
She then called out to me, asking to come help with the laundry.
I was surprised, my sister started to hurry and cover herself like nothing happened. And I put my dick away, then headed down the hallway.
I went into the laundry room, and said, sure, what do you need?
She, in a very low voice, said, I saw you and my daughter just now. I don’t want you getting her pregnant. If you promise to not fuck her, I’ll let you fuck me.
I was very surprised! I almost didn’t know what to say!
I said, seriously? And she turned around, bent over the dryer, and lifted up her nightshirt, exposing her bare ass, (where’d her panties go?) and she spread her legs, allowing me a perfect view of her cunt from behind…
She isn’t bad looking, and she is like most married women, a few extra pounds, but not so much as to say she is fat.
And here she is, offering herself as tribute instead of her daughter…
I came up behind her, pulled down the front of my lounge pants, exposing my very hard cock, and I started rubbing it up and down from the front of her crack, to her perfect ass pucker…
I did this a few times, and as I passed her opening, she pushed back, and I slid neatly into her pussy.
She was, well, “tight”… It felt absolutely amazing!
So I fucked her from behind… She was rubbing her clit, and it wasn’t long untill she climaxed. And right as she did, the extra squeezing her hole was doing got me off, big time, and I unloaded in her. I guess I should have asked first, but I didn’t, and she didn’t seem to mind.
I kept cumming, and she climaxed a second and third time, all while I was still fucking her from behind, shooting cum inside her.
After I finally finished, I pulled out, she turned and took a look at my still hard and throbbing cock…
She said, that was amazing, and you are so much bigger than your dad. And I looked at her, and saw my cum running down her leg…
That got me thinking… What about my dad?
Wouldn’t he know she’s getting some on the side with her stepson?
She then said, you can do it all you want, if you just promise to not fuck my daughter.
I said, ok, because I’m not stupid. But I was thinking I’d still like to fuck my sister…

I went back out to the living room and my sister was gone. She must’ve gone back to her room.
I wasn’t yet recovered from my stepmom’s fun, so I had some breakfast and prepared to go get my car out of storage… After breakfast I got dressed and left.

I returned after about 2 hours, getting the ’70 Mach 1 up and running, and came into the house.
It seemed everyone was gone, so I went to my room and got some clean clothes, took a shower, and headed to my room.
I entered my room and my sister was in there, naked in my bed…
So much for getting dressed.
I asked if she was on birth control, and she answered in the affirmative. And I told her about what her mom saw that morning and what she said to me, about not getting her pregnant… But I left out the part about free sex…
We kinda laughed about it all and I dropped my clothes off and climbed into bed with her.
She started sucking my dick, and I have to say, she must have had a couple boyfriends, because she was good and practiced.
When I thought I was going to cum, I told her to climb on, and she did. Expertly lining up my dick with her pussy, and lowering herself on to me, slow and easy.
Her facial expression was one of discomfort, and I asked if she was ok… She said the boy who popped her cherry wasn’t near as thick as I am, and it was stretching her..
But she took it all, I was now balls deep in my sister’s cunt.
She rode me for about 15 minutes and she reached orgasm and she kept going wanting more.
After the 3rd, I was getting ready to blow my load… Thinking I’d just push her up and off to cum, but she wasn’t having any of that noise.
She clamped down hard, as I was just achieving my, “too late to pull out” time, and I ended up filling my little sister’s pussy with my man juice, just like I did her mom, earlier…
I said, I was going to pull out, so we don’t have an accident.
She replied, it’s ok, I’m on the pill and I have “plan B”…
Well, ok then…
Her pussy was twice as tight as her mom’s, and I was going to enjoy it as long as I could!

Now, the epilogue:
I won’t go into too much detail, as there are still many stories to tell…
But, I’d been home about a year, and my stepmom announced that she was pregnant.
My dad, of course, thought it was his, but I’m pretty sure he uses condoms… Something I never do. I just assumed my stepmom would do what she needed to do to prevent pregnancy.
Now, I’m not sure, we’ve never done a DNA test…
But I think “my little brother” is also “my son”…

Oh, and no, my sister never got pregnant… I mean, well, she DID, eventually… But it was after she married this guy she’d been dating, about 10 years after we fucked in my bed for that first time.
She now has 3 kids.
Who knows, maybe one of them is mine, too?
I haven’t thought about it, but she and I still fuck from time to time.

I still do my stepmom, too… She has me over to “fix something” when Dad is at work…
And always “pays me” with some very good and comfortable sex. We always have a good time.

As far as I know, my dad remains clueless about our affairs.
