If the hottest girl you know walked in to your room and remanded you have sex with her “right now” could you deny her? Would the fact she is your sister change your mind? Yeah I didn’t know either until the other night now I know. The answer is absolutely not! She demanded and I provided it’s that simple.



We live in the absolute middle of no place. There are 100 kids total in our school grades K-12. In our grade there are 4 boys and 3 girls, the totals are similar in other grades above and below. It is needless to say that this makes for a somewhat limited dating pool. Sure every year a few more girls or guys enter the pool, but not all are of a mind to participate fully…you can only go above or below your level in the pool by a certain amount before its sort of creepy. My sister and I fraternal twins so we are pretty much participating at the same level. I can go a little lower than her and she can go a little higher than me looking for match-ups, but we are in the same general area. Unfortunately given the limited overall size it doesn’t take long to burn through all the potential connections. That’s pretty much what happened to Sara.

I was sitting at the desk in my room trying to work through some damn ugly math problem in my homework when Sara walked up to my open door and knocked on the door frame. I didn’t turn around, I just answered her.



“Hey what’s up Sara?” we were home alone until our parents got in later that night from a day trip to the city, so it could have only been her.



“You got a minute or two?” she asked



“Sure, one sec let me just finish up this math problem” I said.



“That number 21 in the homework, yeah that one was a bitch, remember to cancel out the common factors than its easier” she said helpfully.



“Oh, right!” I immediately saw what she meant and was able to quickly solve the problem.



“No problem, your better at English, you owe me one on the next what does it all mean homework question, we make a good team, eh” Sara said



“Ok, then that’s done, what can I do for…” I said as I turned to the door “…ah.. you” I finished after taking in the sight of my sister standing sideways at my door in shinny black satin bra, thong, garter belt and thigh-high lace top stockings. This was a good look for her, we have never been all that modest around each other; we pretty much think nothing of walking around the house in our underwear when we are alone together most of the time, and usually make the walk from our rooms to the shower and back naked. Seeing Sara in this outfit though just seemed totally different though!



“Well that leering look is a good start...” She smiled “…but I need more I’ve kinda run out of viable candidates for fun.” She continued walking across the room “Pretty much every guy that’s not tragic, a mama’s boy, or a saint, I’ve either dated and it’s not worked out long enough to have sex with them, or I’ve had sex with them, and that’s not worked out either.” She reached my chair and nuzzled my neck bending over the back. “I figure it this way, we’ve been together all our lives, and you’re someone I’ve loved from the start.” She stepped around and kissed my lips. “Why not take it to the next level?”

“yeah, why not, I mean it’s not like we are sneaking around in public, who’s gonna know” I started “My only worry is that I’d be cheating on Cara sorta, and I like fucking her, but how would she know, not like anyone can see me taking another girl to my place, or me going there…your already here” I turned and kissed Sara slipping my tongue in to touch hers briefly, and caressing her ass. We held the kiss for a minute, then she pulled back.



“No worries there, I talked with Cara, and she’s willing to share with me, as long as you keep fucking her, and she can play with both of us once in a while”



“Well then I’m not arguing” I said.



“Good, can we start right now then…I’m really freakin’ horny” Sara responded.



“Ok, sounds fine to me”



“Just one thing before we get all naked, I’m having my period.”



“eh, I’ve earned my bloodwings, I even like it when its messy, warmer and slipperier…I’m not going down on though, that’ll have to wait”



“Good by me, I really just want a good hard fucking”



I reached my hands up and carressed Sara’s bra covered breasts and kissed her again hard on the mouth. Her tougue slipped into my mouth and I sucked on it as a ticked it wit my own. I pressed Sara’s breasts hard in my hands. Her nipples stood up hard against the fabric of her satin bra, and pinched them between my thumbs and fingers. Sara kissed me harder, I pressed her tougue back with my own and now we were in her mouth. Sara reached down, unbuttoned and unzipped my pants. Her hand then slipped into the flap of my boxers and puleld out my cock. It felt so good to have her hand around it as she started stroking.



We remained at the chair kissing and fondling for a while enjoying the kissing and fondling. However I was getting very tuned on and I now needed very badly to be inside of her. I stood up throwing my hands under he ass and picked her up stradling me and carried Sara to the bed. I laid he down on the end and slipped her thong off while I still held her ass in the air in my hands. I pulled off my boxers and then crawled on to the bed over Sara. Once I was over her I reached between her beasts on opened the front closure of her bra. Her firm young breasts stood at attention with erect nipples demanding my attention. I bent my head down and tickled each with the tip of my tongue, getting a gasp from Sara with each. Then one at a time I took each in my mouth as I massaged the other breast with a hand. I sucked each nipple firmly and yet gently. Sara moaned and gasped.



“Oh God, OH…Yes….OOOHHH” Sara moaned. “oh, I’ve never had an Orgasm and not even been fucked yet!”



I reached down and put my arms under Sara’s legs now bending them up as I aimed my cock into her waiting cunt. She was warm, wet and very slippery with pussy juices and her blood. My cock slipped right in to her tight enbrace. I started slowly pulling and pushing in and out of her taking my entire length out right up the head with each stroke. After a few minutes as out excitement started to build, she moaned “Oh..Harder, fuck me” I responded by starting to thrust my cock hard and deep quickly on each in stroke, but still pulling myself out slowly. After several minutes more of this she gasped and screamed in one long held note like and Opera singer at the climax of the show. I felt her insides twitch and clamp against me in orgasm.



With Sara now twice satisfied as she came down from her orgasm. I quickened my pace to now get what I needed. I was now furiously thrusting in and out makin a foamly mess of pussy juices, and blood, Sara screamed and twitched again in orgasm number three. I let go of my restraint now and came with her adding my own long low moan. I felt my cock twitch with squirt after squirt of cum now mixing with the other juices of our encounter. I continued thrusting until my cock went soft and flopped out of Sara’s cunt. I wanted to hear Sara scream one more time I reached down with my left index finger and found her still erect clitorus and rubbed in circles. She gasped moaned and screamed again low and now exhausted.

“Oh…that was sooo…goood!” She continued panting

“UH, you weren’t too bad yourself.”

After that we both feel asleep cuddled for several hours until we heard the garage door opening.
