My Sister Said OK

Growing up, I didn't particularly get along with my younger sister. We seemed like we lived in completely different worlds. But the summer I was 17 changed everything and life would never be the same again.

My parents were heavily involved in our church: my father was a Junior and then Senior Warden, and my mother was assistant choir director. This didn't affect me much except that they were both gone after dinner every Thursday night until after 10. It was one of the few times that my sister and I were home alone together. We typically wound up watching TV together in the living room and more or less ignored the other's presence most of the time.

This was the late 70's and for what ever reason, the fashion for girl's pajamas was the baby-doll nightgown: tight on top with a flared skirt that barely covered the bikini bottoms underneath. My sister was not well endowed at that age, but this outfit emphasized what she had. I was not in the habit of "checking out" my sister, but with her lying on the floor in front of me, ass barely covered and tits barely contained by the top, I did notice her.

I also noticed that her legs looked quite sunburned and that she was itching her back and butt, and squirming like she was uncomfortable.

"Did you get a sunburn laying out today?" I said.

"I guess" she replied.

"Your legs look pretty bad. Did you put anything on the burns?" I asked.

"No, what's the point?" she answered.

"Well, as the fair-headed one in the family, I know that if you feel uncomfortable now, you will be going crazy tomorrow when it really starts itching" I said. "There should be some calamine lotion in the upstairs bathroom; do you want help putting some on your back?"

"OK" replied my sister, who went upstairs and returned with the bottle.

"Turn around and lift your top" I ordered. I read the instructions on the bottle which stated "MAY STAIN FABRIC WHEN WET."

"OK" she said and turned around.

Her back was red and already peeling in places. I pushed her top up a little further and didn't see any sign of tan lines.

"Did you lay out without a suit on? You're going to need to take off your top so I can get to your shoulders" I said.

"OK" replied my sister and peeled off her top. I expected her to hold it on her front to hide her breasts but instead, she just dropped it on the floor. I could see the sides of her breasts, which looked just as red as her back, if not more so.

I squirted some lotion on my hands and began gently applying from her shoulders down. When I reached her waist, I lifted the corner of her panties and could tell that the sunburn extended onto her butt as well.

"Did you seriously lay out in the nude? You're completely burnt everywhere. Do you want me to put the lotion everywhere?" I asked, not expecting her to agree.

"OK, she replied and pushed down her panties. My sister stood in front of me, completely nude. I hadn't seen her naked since she was a baby. She might be my sister, but she had a nice ass and legs. I continued to apply the lotion to the back of her legs, which she spread slightly to make it easier to apply the lotion.

As my hands moved up her inner legs approaching her pussy from the rear, she spread her legs even wider, like she was daring me to touch her. I barely grazed her labia and she shivered, but said nothing. I made a big production of applying lotion to her ass as well, making sure that her asshole was well covered. Again, she said nothing but moaned almost in a purr as I pressed gently against her tight asshole, which seemed to loosen as I pushed.

"Do you want me to do the front as well?" I asked hopefully.

"OK" she replied and turned around. Her breast stood high on her chest, with prominent nipples. Her mons was lightly covered in fine hairs but her labia were clearly visible. Moreso, her clitoris was engorged and rose prominently displayed from between her tightly closed slit.

I started covering her body with lotion, starting from her shoulders on down. When I reached her breasts, I deliberately slowed and rubbed in circles around her nipples. She breathed in sharply and it seemed like a flush spread across her cheeks and she got a distant look in her eyes.

I continued applying lotion to her waist, then moved to do her lower legs and again converged on her crotch. I don't think it was my imagination that by the time I reached her upper legs, she was thrusting her hips forward rhythmically. I decided to go for it and started applying the lotion directly to her pussy, rubbing her labia and skimming over her engorged clit. She moaned and humped my hand, then shuddered in an obvious orgasm.

"That was fun!" I said. "Do you want to sit on my lap now, since you are all greasy?"

"OK" replied my sister and she sat, naked, on my lap. There was no possible way she could not notice my boner and in fact, seemed to be deliberately sitting on it.

"Stand up for a second" I said, then stood and pulled off my shirt and shorts. She looked at me with a little fear in her eyes but said nothing.

"You're naked, so I may as well be naked too!" I replied to her look.

"OK" she replied and after I sat down, she returned to her seat, my erection nestled between the cheeks of her ass.

I moaned slightly and started humping my hips a little, so my cock was moving in between her cheeks, which were still slick from the lotion. She set up a counter motion so my cock was rubbing up against her asshole on every pass.

I reached up and grasped her breasts from behind and gently squeeze her nipples between thumb and forefinger and was rewarded by a gasp and then another moan. I continued to thrust my cock back and forth and she hunched her hips so that my cock actually caught a little each time I moved past her sphincter.

After one such catch seemed to last for a while, I told her to lift up a little, then grasped my cock and gave it a quick wank to distribute the lotion over the whole surface.

"Sit down slowly" I said, holding my cock vertical and aiming for her asshole.

"OK" she murmured almost to herself, then began lowering herself and impaling her ass on my cock. The feelings for me were incredible and as she pushed more and more of my cock into her, she began panting.

By the time her ass touched my thighs, I wasn't sure how long I was going to last like this, but I was determined to make it as long as possible. She wiggled a little to settle the cock even deeper. I pulled up on her nipples and she followed, then pull down, until I set up a rhythm of pulses in and out of her ass.

She was openly moaning and panting now, like it felt good and hurt at the same time.

"I want to stand up slowly so I'm still inside you." I suggested.

"OK" replied my sister distantly and we both carefully stood up. I had to stoop just a little to keep my cock seated firmly in her ass. I pushed her down on her shoulders while holding onto her hips, and began to thrust in and out more vigorously now. I was definitely fucking my sister's ass and she was thrusting back with just as much force.

I noticed that her hand was between her legs and I heard the sound of her fingers playing with her cunt. The room was otherwise silent except for the slapping of her ass as I fucked harder and the continuous moaning, almost keening, that my sister was making.

All too soon, I felt the familiar pressure of an orgasm build up and I pounded harder. Her arm moved and her fingers made a squelching sound as she redoubled her efforts. Just before I came, I heard her cry out in ecstasy and I pounded twice then held her hips hard while I shot cum into her bowels. She continued to rub herself and shudder, then slowed and stopped.

I pulled out of her and noted a little brown smear on my cock, but otherwise not too bad.

"You better go into the bathroom" I said "before you start dripping on the carpeting."

"OK" replied my sister, reaching down and grabbing her pj's before running upstairs. I went to the downstairs bathroom and cleaned my cock carefully, because the tip was still ultra sensitive. I returned to the living room and put my pj's back on and sat down to watch the rest of the program. After a few minutes, my sister came down in her pj's and lay back down on the floor to watch TV.

"That was amazing and if you are interested, I'd love to do that again next week, only maybe this time in your pussy!" I said, hope against hope that she wouldn't shoot me down. I was a little worried actually that she'd regret what we did and tell Mom and Dad that I'd raped her.

Instead, my sister turned around to look at me for a long time and said "OK" with a smile.

After that, Thursday was our special day and we would start playing around as soon as Mom and Dad had left for church. I was sad when I went away to college, but I knew that whenever I visited, I could ask my sister if she wanted to fuck and she'd reply "OK" every time.
