"That's the plan," I said carefully, sensing she was up to something.

"Good. Then since you're sleeping here... I'd like it if you slept with me," she said, biting her lip expectantly.

I stared at her for a few seconds. I'd certainly like to, if she really meant it.

"Are you serious?" I asked, conditioned to expect her to be teasing.

"Yes," she answered immediately, nodding. "I know guys are supposed to be bad at taking hints, but I don't think I can be any clearer than that," she said, grinning wider.

"Uh, that's extremely forward of you-"

Melissa interrupted me, reaching up and pulling my face down to kiss me. She was good at it too. She latched on to me, wrapping one leg around mine and pushing her body hard up against me.

I could hardly believe it, but wasn't about to question it. I grabbed her, pushing her back against the wall. She moaned into my mouth as I returned her affection, my hands roaming over her body.

She pulled back, smiling at me.

"You're not a bad kisser," she complimented. "I've always wanted to do that."

"Then why haven't you?" I asked. "I always assumed you just liked messing with me."

She held on to me, keeping her tits mashed against my chest.

"Well, your sister is my closest friend... You must have noticed how she gets about you?"

"I guess..." I answered. She had a point.

"But she's not here right now," Melissa purred.

When the house had gone quiet and everyone seemed to have left I walked upstairs to Melissa's room. She had disappeared before the last guests left, and I had taken it upon myself to see them off instead.

Anna was nowhere to be seen, so I assumed she was already asleep. Which left just me and Melissa.

I had been fantasizing about her for years, on and off. Still, it felt weird walking up the stairs, slowly getting closer to her room, and presumably sex with her. I guess I'd always been aware that my sister stood in the way of any relationship between me and her. How would she react if she found out?

We were both adults now, though. It didn't seem reasonable that I would allow my sister to dictate my love life. Those thoughts in mind, I walked up to the door.

Surprise me a note said, taped to the white wood of the door.

Surprise her? I supposed I can do that, I thought.

It was pitch black in there.

After a moments thought, I decided to close the door behind me either way. With any luck we'd be making a lot of noise before long.

I carefully stalked over to where I knew her bed would be. I could see the dark outline of Melissa, laying on the bed. She wasn't speaking. Hopefully she wasn't asleep.

She did say to surprise her, I thought.

Her moans intensified as my mouth met her nipples. It was incredibly hot, to finally be able to suck and lick her amazing breasts. They seemed smaller than I had thought they would be, in the darkness of the room. Not that it mattered. At that moment, they were perfect.

I licked, massaged and worshiped her tits, leaving her nipples hard and coated in a layer of saliva. Melissa breathed heavily above me, stroking my head encouragingly.

I was very hard, and eager to release the tension that was building up in my cock. Still, I knew that the first impression was vital, and I was determined to leave a good one.

Slowly, I moved down along her body, kissing and licking as I went. I could feel her shiver as I passed her sexy, flat stomach, getting closer to my destination. I got off the bed and sat down with my knees on the floor before reaching out and pulling her closer to me.

She had on a thin, lacy pair of darkly colored panties. Her heavy breathing filled the room as I bit into the top of it and pulled it down with my teeth, eager to get to what was underneath.

"Oh god," she whispered silently, between breaths. Her voice was excited, sounding lighter than usual.

"What do you mean, supposed?" I asked, standing up. "You did this? You set us up?"

"It was supposed to be funny," she said in a panicked voice. "I didn't expect you to go straight for, uh, you know..."

She looked to Anna and back to me. "How the hell did you guys not notice anyway?"

She had a point. I should have noticed, even in the dark, that it wasn't Melissa. Holy fuck, I thought. I ate out my own fucking sister!

A few, extremely awkward, seconds passed as we let what had happened sink in.

"Fuck..." I said, breaking the silence, not knowing what else I could say.

"Sorry," Melissa mumbled, looking extremely apologetic.

"I... need to get home," I said, walking out of the room. What else could I do? I needed time to process, on my own.

"W-Wait," Anna called out to me from the room. A few moments later, she met me in the hall carrying most her clothing with her in a bundle.

I didn't object. It wasn't like she had any other way to get home, after all.

We left without saying goodbye. Without saying anything, really.

The ride home wasn't any better. I tried to concentrate on the road as Anna put on as much of the clothing as she could manage in the seat beside me.

Perhaps I should have said something. But what could I say? Sorry, I thought I was about to fuck your friend, not you? Or Whoops, I guess I ate out my little sister. My bad?

We managed to get home, and into our separate rooms, without so much as looking at each other. Sleep came with great difficulty.

"I-I don't feel that way. I don't resent you at all. If anything, you should be disgusted by me," she exclaimed, grimacing at the last part.

"No, Sis. I'm definitely not disgusted by you," I assured her. "Let's just... put it behind us. I'm kind of missing spending time with my little sister."

"I miss it too," she admitted. "These last few days have been horrible."

I smiled at her, and she returned my smile.

I couldn't help but see the absurdity of the situation, and let out a relieved laugh. Anna joined me in my fit of laughter, and before long things felt like normal again.

"Thanks, Bro," Anna said, moving over to hug me tightly, resting her head on my shoulder while I held her toward me.

I did feel a spark of attraction as I held on to her though, a feeling that I desperately tried to ignore.

I released her, and stood up to leave.

"Sam?" Anna asked, stopping me.

"Yeah?" I turned around to face her. She was picking at her nails, an uncertain look on her face.

"Was I... was it good? T-The kissing, I mean," she quickly added, face turning scarlet.

That certainly caught me off guard.
