So, as sometimes happens, my sister got left at the altar by a dumbass. After the requisite crying and anger, throughout which I had to comfort her since our parents were both deceased, she calmed down.

Mostly, anyway.

I had an idea to help her calm down the rest of the way as well as take a little bit of revenge on her fiance. “Well, the honeymoon trip is already paid for and you were supposed to be leaving tomorrow. Why don’t we go? Have a nice trip on his dime, eh?”

She’d been holding the tickets, etc., so we got away with it. Oh, of course she had to tell him over the phone that it was the least he owed her. He agreed. Then we had to quickly explain the circumstances to the travel agent and get the names on the tickets changed. Most notably from his name to mine.

Then we ran to my home so I could pack. She got weepy again and we cuddled that night like we used to when we were teenagers and she had a bad dream or a nasty breakup or whatever. The one thing that was different was that her tits and ass were bigger, more well defined. There was quite a difference between her current age of twenty-five and how old she had been when I left home, which was fifteen, after all.

Oh, and the other thing that was different? I woke up holding her tits. See, at our ages, we were used to that - me with other women and her with her fiancee. So in our sleep we didn’t realize. When I woke up, I realized what I was doing and slowly disengaged from her.

Successfully, I thought, since she didn’t rouse for another ten minutes when she heard me moving around in the bathroom.

We took our time getting ready and eating breakfast. But eventually we had to leave since her suitcase was still at her place. So we rushed over and when we got there, she got a weird look on her face, like she realized something. She bit her lower lip and looked at me.

“How much time do we have?”

I looked at my watch. “Not much. We really should be on the road in like five minutes.”

She shrugged like she was saying Fuck it and picked up her suitcase. “Let’s go.”

I didn’t think much of it since we were in a hurry.

I really should have.

See, she’d packed for a honeymoon. Something we’d kind of forgotten in our rush.

And when we got to where we were staying at a nice beach resort, she showed me exactly what she’d packed.

No normal underwear. Just lingerie.

Clothes that said “Come fuck me.”

Then she sat me down and laid it out. “You’ve been there for me my whole life, in pretty much every way. Last night felt awesome, including when you were holding my tits. It felt more right than when dumbass held me. If we weren’t brother and sister, I’d have married you right out of high school. Last night and this morning made me realize something - I don’t care anymore. Especially now that Mom and Dad aren’t around anymore. Now, you have a choice. Either this is our honeymoon and I wear this stuff all week and we do what comes naturally. Or I go to the resort store and buy some underwear and normal vacation clothing and we’re just brother and sister. So which will it be?”

I grinned at her. Last night had felt right to me as well. I nodded to myself and reached into her suitcase and pulled out a sexy red bit of nothing. “Go put this on, wife.”

She giggled and grabbed it from my hand and ran to the bathroom. After a little while, she came out dressed in something that looked even better on her than I’d imagined when I saw it in the suitcase.

Our first fuck was quick and frantic. The tears we both shed afterward were cathartic in a very different way than the night before. We admitted to each other that yes, we really did love each other and this first fuck had felt perfect.

The next time was nice and sweet and gentle. And then we started our honeymoon. And every time we went out, she had no underwear on wearing clothes that screamed “come fuck me!” My favorites were the thin t-shirts she had that were thick enough not to show areolae but thin enough to show me when she was aroused.

And whenever we were alone - which was frequent because this was a honeymoon resort, after all - I did what her clothes said - I fucked her.

Now, as luck would have it, I was at a point in my career where if I wanted a promotion in my company, I basically had to move to another city. I’d resisted it for a year or so, wanting to stay near her since she was the only family I had left. But now it could work in our favor. So our pillow talk often included talking about just which city we wanted to move to.

And the fact that she wasn’t on any sort of birth control since she had felt ready to go ahead and get started on a family. She said she felt like that even more strongly so we didn’t bother buying condoms. It felt awesome spurting in her unprotected pussy knowing we could be making a baby. And every time I saw her firm braless tits, I thought about a baby sucking on them which made me ready to fuck her again.

She never objected. In fact, once she figured out what had me so randy, she always giggled whenever the sight of her tits made me hard.

When we were finally on the flight home, I leaned over and whispered “I don’t like seeing you in a bra anymore after the past week. And I think you know I really liked those white t-shirts. I want to see you in them all the time at home.”

She just giggled.

And nodded. “Of course, hubby.”
