The morning after I made love to my sister Becky for the first time I woke up with a pounding headache. We had all had a lot to drink, after all. And while I was grateful for the loosening of inhibitions that led to pleasure, my pain presently was undeniable. Maybe it was that, or maybe you're just supposed to feel a little guilty after cumming inside your sister, but I had a mild bout of anxiety and disquiet.
I was lying on their bed, on the far side of the room away from the door and closest to the sliding glass balcony door. It was still only 7:00 a.m. but the room was already filling up with bright sunlight despite the drawn curtains. I realized in a moment it was from the window of the small bathroom near me. As my eyes adjusted to the light and I shook the sleep off, I took in the room around me. Like many girls' rooms, Becky and Tammy's bedroom was filled with soft colors and in the early morning it was giving the room a sort of pink and peach glow. Lying on my back, I turned my head to the right and looked upon their sleeping figures.
They were in a half-embrace, a light cotton sheet covering them. They probably got cold overnight, I thought, but I was sweating a little. Probably the alcohol, but the room was starting to feel a bit warm. Becky was closest to me, and the sheet was only half covering her. Like me, she runs a little hotter than even most girls, but I could see Tammy was cuddled up snugly under it with her knees pulled up almost in a fetal position. Her left arm was under the pillow Becky was sleeping on, her right arm stretched out with her hand resting on Becky's hip. For her part, Becky was sprawled out almost face down. Her back was towards me, her right arm under her pillow, maybe clasping Tammy's hand, but her left arm thrown back behind her almost as if we had been holding hands. Like I mentioned the sheet was only half covering her, with her legs under it but her back exposed. I remembered that she always was a fitful sleeper and got hot easily. I had known for years that she preferred to sleep in the nude, and it was only a half-secret between us. For that reason she had never been a fan of sleepovers. And she absolutely hated family trips because we had to share a room, especially if it was a big family gathering and there were cousins involved.
For my part, I had always found her preference curious; thrilling, even. As we got older I had often masturbated thinking about her getting ready for bed. I would imagine her stripping out of her pajamas. Did she admire her own body as she did so? Is that when she decided if she was going to touch herself? Maybe sometimes she fell asleep before undressing, and would wake up sweating. I fantasized about sneaking into her room. Maybe she would wake up and invite me in. I would put my hand on her pussy to find it wet and waiting for me. I usually slept naked too, or in my boxers. Did she think about that? Sometimes I heard her get up in the middle of the night to use the bathroom. Did she go naked? Or did she have to get dressed before stepping out? Maybe sometimes she didn't bother. Maybe sometimes she hoped I would catch her. Or: maybe sometimes she thought about sneaking into my room, slipping into my bed, And finding my cock hard and hungry for her.
I lay there remembering those fantasies and what had happened the night before, when I noticed she was wearing panties. The same pink panties she had on last night, when she spread her legs and then humped me on the couch. The pink panties she took off and let fall on the floor soon after, just before I put my cock inside her. And then I noticed that under the blanket Tammy was wearing a white tank top. Not the green one she'd had on the night before (I think that was probably still in the living room).
For some reason that made me worried. It seemed like an odd bit of modesty after what we had all done together. Did they regret it? It occurred to me that they were a couple; a lesbian couple at that. Did they resent me getting between them? Had I put their intimacy at risk for a lay? As much as I wanted my sister, I did not want to cause her a headache. I knew how messy group sex could get. Just the year before a friend from work had invited me over to his house. After meeting his wife, he had told me that she was attracted to me and wanted to sleep with me. To my surprise, he was very eager to let me sleep with her. I took him up on it, and we all three had a bit of fun for a few weeks.
But, after a while she got a little too attached to me, and he began to resent me. I think she had genuine feelings for me, or maybe she did not have those feelings for him. I was confused because it hadn't been my idea to begin with, and I assumed as adults they had all that stuff figured out ahead of time. I had a heart-to-heart with the guy and apologized, saying I had not intended this. I suggested we should stop. At first he seemed grateful, but then after another week he became really hostile. I got the feeling his wife was upset at not seeing me anymore, or being left out of the decision. But I never asked, and I ended up leaving the job soon after that. It was unfortunate because I liked them both, but I guess things went too far and I had gotten mixed up in a real relationship.
All of this was rolling around my head that morning. My heart even started beating hard. Maybe they had stayed up after the sex, even though I had thought we all drifted off together. Maybe Becky or Tammy, or both, regretted what had happened. Maybe one or both of them cried. Maybe they hated me, and wished that I'd go away, but like a dumb ape I was passed out drunk next to them. I felt terrible, like a nuisance and an interloper. And I was aware that a lot of this was paranoia, but I have always listened to my gut and my gut was telling me to leave them alone. For once I was grateful at being an early riser, as the two seemed still deeply asleep, and I quietly moved off the bed.
As I stood I remembered that I had made to their bedroom fully clothed, and started looking for my clothes on the floor. Typical women, their room was covered in clothes. But mine were easily found on top of the mess, piled up next to the bed where they had undressed me as we kissed. That was a sweet memory, but again I felt troubled remembering how drunk we had all been. I found my boxers a little farther away, at the foot off the bed where I had kicked them off after Becky pulled them down and begged me to fuck her. It was all coming back to me now, and I started to wonder if I was making something out of nothing. Still, it didn't seem a bad idea to leave them alone for a while. If they hadn't talked before, maybe they would like to now. Quietly I gathered my clothes in a bundle and picked them up.
As I stood up, my belt jingled somewhat loudly. At this Becky made a little moan and writhed around, sighing softly. But she did not wake up and instead brought her left arm up. Finding Tammy she hugged her closer. Tammy was really out, making only a small adjustment as Becky drew closer. They looked beautiful. I thought about putting my worry aside and joining them again, but by now I was feeling silly anyway so I stuck to my plan. Fortunately the bedroom door was wide open, so I made my way out and down the short hallway to my bedroom.
