I have written several stories involving step-siblings and I usually get a few comments explaining to me that sex between step-siblings is not incest. I already know that. However, sex between step-siblings is taboo. Very taboo. If you don't believe, ask your step-dad if you can fuck his daughter. This story is posted in a category entitled "incest/taboo." The category is not entitled just "incest." If this bothers you too much, just don't read the story.
=====================
We were summoned to the family room for an announcement by our parents. They were both present but Mom did all of the talking.
"Your father and I are going to Europe next month and we're gonna be gone for 28 days. We've talked about it and decided that you are too old for a babysitter so we're just gonna have to trust you guys for a month. All the bills will be prepaid, we'll leave money for groceries, and we'll leave a debit card for emergencies but we'll want a receipt for every expense you put on the card so don't think of it as fun money! Understand, Will? Understand, Crissy?"
That was how my mom told me and Crissy that she and my step-dad were going on vacation. We knew that it was their anniversary and we thought they might go out of town for a few days. Crissy had even talked to her boyfriend about spending the night with her while the parents were gone. She asked me if it would be okay and I teased her by saying that I didn't care as long as I didn't hear her moaning and banging on the walls.
I had teased her about the idea but I was actually rather jealous. Crissy is my step-dad's daughter but she and I have lived together since before kindergarten. We are the same age - both turned 18 a few months ago - so we have always been in the same grade, had the same friends, and we've been close.
Lately, I've been getting aroused when she has showered and changed into her night clothes - just panties and a cut off tee shirt - and she then comes in to my bedroom to talk. The moisture on her skin makes the panties cling rather tightly and it displays a very obvious camel toe.
I know I shouldn't get aroused seeing my step-sister in her panties and bra but I can't help it. I try not to stare, but I'm a horny guy and she's a real cute girl. I don't have much sexual experience and I just think about sex all the time.
Crissy and I always talk about what's happening in our lives and she's told me about her boyfriend, Brad. Of course, I know him and he's an okay guy but not my favorite. Actually, he's kind of a stuck up bastard and I think my sister could do much better than him, but . . . maybe I'm just jealous.
Crissy told me when they made out the first time. She also told me when she gave him a hand job and when he fingered her until she came. Just hearing about it got me aroused and, of course, I wished that it had been me instead of Brad. After the left my bedroom that night, I ended up jerking off just thinking about it. I fantasized about fingering Crissy but fantasy is not a substitute for the real thing. I'd really like to see Crissy naked now that she is 18 years old. I know it's kinda sick but I can't help how incredibly horny I get!
Crissy isn't a classic blonde cheerleader but she is cute. She has a very pretty face, straight blond hair, and she has an athletic body. She doesn't have big boobs; in fact, her bra size is 32B. I know because she sometimes leaves her underwear on the bathroom floor after she gets out of the shower. Of course, I looked at her bra. And, I'll admit that I've sniffed her used panties. Like I said, I'm a horny bastard and jerking off to her panties . . . and her aroma . . . it's SO much better than just jerking off to porn. Smelling where her pussy has rubbed against her panties makes me want to put my tongue in her pussy just like in the porn I've seen.
Anyway, Mom and Dad (he's my step-dad but I've always called him "Dad") were leaving in about two weeks, at the beginning of July. We had graduated high school and were both starting at the local junior college in late August. We both had part-time jobs but we had plenty of free time on our hands.
Crissy and I decided to have a talk to plan what we were going to do during our two week "vacation." We weren't stupid and we weren't wild kids and we knew not to throw any wild parties. Crissy just wanted to have time alone with Brad. I had the idea that she was ready to have sex with him and wanted an opportunity when they would have plenty of time.
I wasn't dating anyone so I didn't have any plans like that. I said that maybe we could go to the beach one day during the week when neither of us was working. Crissy said that she had always wanted to do some nude sunbathing around our pool but would never do that if there was any chance that Mom or Dad might catch her. Then she added, "I'd probably be a little bit embarrassed about you seeing me, but you've seen me in my undies lately so I'd probably get used to it pretty quickly." The idea of seeing Crissy naked made me hard immediately.
Mom and Dad talked about their vacation non-stop for the next two weeks and it got to be fairly irritating . . . except that we were looking forward to having almost a month without them. Finally, the day arrived and we drove them to the airport, got the usual warnings about not burning down the house, call them if anything happens, have a good time but not TOO good!
On the way back home, Crissy said that she wanted to see Brad so she asked if she could drop me off at our house and then she would keep going to see Brad. We shared a car. She dropped me and disappeared en route to see Mr. Wonderful, the lucky bastard boyfriend. I went in the house, changed into some loose gym shorts and a t shirt, and called a friend whose older brother worked at a liquor store. I wanted to arrange to pick up a bottle of vodka. Neither of us drank very much but we both preferred vodka when we did drink.
Neal said that he could get a bottle later today and even said he would front the cost if I promised that I was good for the cost. Of course, I reassured him and he said that he would have the bottle by late afternoon. It was already 3 pm so I had no complaints about that service!
Around 6 pm, Crissy had still not returned so I pulled out a frozen pizza and put it in the oven. Neal stopped by the house as the pizza was coming out of the oven so I offered him a few slices, paid him for the vodka, and put the bottle away so I could surprise Crissy later. And I hoped that she would not have Brad with her when she returned. I didn't want that asshole drinking the vodka I had paid for.
Crissy finally came home about 8 pm. I was relieved to not see Brad with her but she was obviously upset. As soon as she saw me, she started crying.
After I wiped away her tears, she told me what had happened the past four hours. She went to Brad's house and he wasn't at home. His parents said that they thought he was at Henry's house so she went there. Henry wasn't home but his mother thought Henry had gone with Brad to get pizza at the Silver Dollar. When Crissy walked into the Silver Dollar, she saw Henry and Lisa sitting in a booth with Brad and Leigha. Brad had his arm around Leigha and they were sitting close like a dating couple would do. Crissy stayed at a distance for a few minutes to see what might happen and, at one point, Brad leaned over and kissed Leigha on the lips.
