"Oh Lynn, that's awful! How long will it take?" I was talking to my little sister, she'd showed up at my door a short time ago. It seems her apartment building was being tented for some sort of insect infestation.
"Oh Rachel, I can't thank you enough," Lynn said. "Since I'm pregnant my doctor thought an extra day away from the building couldn't hurt, could I stay for... five days? I hate to impose on you and Brian."
"Don't be silly," I said. "You're my only sister! And you're making me an aunt!" I gave her a big hug to reassure her. She was six months along and glowing. Shiny blonde hair to her shoulders, big blue eyes, swelling tits and a big belly, she
looked
fertile.
"Besides, Brian's out of town until Friday, he's got that conference in Philly. I could use the company." The house was a touch big for the two of us, we were hoping for kids too, like Lynn. I got her set up in a spare bedroom down the hall from me, in case she needed anything in the night.
Well she needed something all right. I heard her for hours the first night, moaning and squealing and sighing, over and over. I knew those sounds well, we'd shared a bedroom growing up. My little sister was pleasuring herself. Listening to her started making me horny too, it took me forever to fall asleep.
In the morning she was bright eyed and energetic, I wondered how she did it. I dragged myself through my work day and came home to hear those same sounds in the living room. How in god's name could she still be horny? I wondered.
I intentionally made some noise closing the front door and setting my purse down to give Lynn time to get herself together. When I got to the living room she was on the couch looking guilty. Her face was flushed and the room smelled of sex.
I sighed. "Lynn, we have to talk." I wasn't in a great mood, being tired from the night before, maybe I was a little too abrupt with her. She shrank into herself and her eyes got that puppy-dog look.
"Rachel, I know what you're going to say, but you've never been pregnant before. I'm getting these...
urges
all the time now. My hormones are going crazy!" I had to give her that, while Brian and I had been trying for a while now Lynn forgot her pill
once
and now she's preggers.
She was
pretty
sure who the father was, but she didn't even bother asking, she was just going to raise it herself. We'd both always wanted kids, she just got there first. I admit I was a bit jealous
She went on, "At least you have Brian. Ever since I started showing I can't seem to get laid. Most guys just don't want sex with a pregnant woman." Lynn had never been one to keep a guy too long.
I joined her on the couch, my feet were killing me. I sat on something and got up, startled. It was a big vibrator, I must have missed it in my exhaustion. I sighed and handed it to my sister. "Yours?"
She blushed again and quickly snatched it out of my hand, getting up and saying "You look tired, why don't I order in tonight? Pizza okay? I'll just go get my phone." She hurried down the hall to her room.
I went to bed early and slept like a dead woman. I woke up in the middle of the night with my mouth tasting awful, I'd forgotten to brush my teeth. I got up and took care of that, then looked in on my sister.
She was sleeping naked like she always used to. Her tits looked magnificent, they were getting large and full. Another thing to be jealous over, Lynn had always had the better figure, in my mind at least. Her nipples were hard and between her thighs was all shiny and wet.
I thought about those soft cries I'd heard the other night, how arousing they had been at the time. I missed Brian, we made love almost every night. I never masturbated anymore, Brian always took care of my needs. But smelling my sister's heat in the air, seeing her nude and satisfied, it was getting to me.
I went back to my room and stripped off my panties. I lifted my sleep shirt up, exposing my breasts. Lying in bed I stroked my pussy, wishing for my husband's cock. I ran delicate fingers up my thighs, teasing myself, getting closer and closer to my poor throbbing clit.
I pinched my nipples with one hand, wanting it to be Brian's mouth on me. The other was busy between my thighs, keeping myself on the edge of cumming for as long as I could. Three bunched fingers were sliding in and out of my hungry cunny, wanting it to be his thick rod.
At last my orgasm hit and I tried to keep from crying out. One hand flew over my mouth as my body rocked, my back arched and I spasmed with bolts of ecstasy. I was grunting and moaning as softly as I could, Brian and I are usually noisy love-makers.
The release was incredible, I hadn't realized how horny I'd been. I was glowing with total satisfaction. That's when I looked up and saw my little sister in the doorway, watching me. She was mostly in shadow, her expression hard to read. But she was panting, clutching the door frame.
Before I could speak she left. I lay awake a long time. It was quiet at first but eventually I heard those soft cries. She was trying to be quiet too now but I was listening hard. for some reason hearing them comforted me, I fell asleep smiling.
I slept like a baby, woke up smiling too. Today I felt much more normal. Was I that used to cumming almost every night? Perhaps I'd been holding back, inhibited by Lynn's presence. I thought about it on and off during the day.
Oddly enough I wasn't bothered that much by Lynn watching me. I'd always been a bit of an exhibitionist, was that it? I was no closer to an answer when I arrived home. Lynn had made chicken pot pie for dinner, my favorite. I supposed partly as an apology.
We talked after dinner. Lynn really did strike me as sincere, she was trying to control herself but her body was making it impossible. I admitted I was still kind of a prude. After all, we're both adults, why shouldn't we be more open about sex with each other?
"I have to say Lynn, last night, what really got me horny was looking at
you
, sleeping naked and looking very satisfied." I blushed as I confessed it to her, I'd never thought of another woman that way, until now.
My little sister was quiet for a long moment. She looked up at me, asking, "Can I tell you something? Don't get all freaked out but... sometimes when I'm cumming I'm thinking of you and Brian. And me. The three of us, together."
That
thought rocked me some. She'd never indicated she thought my husband was especially sexy, and why was I in there too? I'd heard pregnant women have strange fantasies... But it didn't bother me for some reason. Maybe because she was my sister, maybe because she included me, I don't know.
"So, what kinds of things are we doing, in these fantasies of yours?" I asked. I felt beet red with embarrassment but I was really curious. I mean, I wanted to have kids too, would this happen to me as well some day?
Now it was Lynn's turn to blush and look away. "Nothing weird, I mean, just normal sex stuff. No whips or chains." Her hand was drifting up to her throat, she started playing with her hair.
"Like what? What's normal for you, sis?" I asked. I was getting aroused, talking with her like this. We'd never been this open with each other before. It felt like this was an erotic dance, the music moving us wherever it wanted.
Lynn shifted on the couch. "Well the one that gets me going the most I guess is, picturing you eating me while Brian takes you from behind." She licked her lips. "And Rachel, if we're going to keep talking about this..."
I helped her up off the couch and we went into my bedroom. Our breathing was loud in my ears as we quietly undressed. Lynn was glowing, she looked fantastic, her belly a smooth, tan oval, her tits looking firmer and bigger than ever.
Lynn was looking at me as if she were starving and I was the last bite of steak. "God Rachel, I can see why Brian is after you every night, you look
sexy
, big sister." Funny thing was seeing her look at me like that, hearing it in her voice, made me
feel
sexy as hell.
Oh god, we were going through with it! I was as nervous as Lynn appeared calm. "Relax, Rachel, come here and kiss me." Lynn patted the sheets beside her and I sank down. I felt wide open, ready for anything.
She was lying down, more comfortable on her gravid belly. Her blonde hair spread around her like a halo. Her lips looked very tempting so I kissed them. It made my head spin, her tongue was flexing around mine, her breath was sweet and hot, intoxicating.
I'd never kissed a woman sexually before, I was amazed at how soft her lips were, how intense the experience was. Lynn moaned into my mouth and I moved down to her throat, licking and sucking.
