It happens every time An Erotic Story I Know I shouldn't let my brother climb in bed with me when we're both naked. No matter how innocently it starts out, it always ends the same way. "Please, Shauna. Just a kiss. That's all, I promise. You know I love you." Yeah right ... just a kiss ... Only I DID know how much my big brother loved me ... that was the trouble. "No," I replied, as sternly as I could. Feeling my big brother's skin against mine was already making me weaken. I shouldn't have let him cuddle up next to me naked in the first place. "That's what you said LAST time," I reminded him. "And look what happened then." "Please?" For all my big brother being three years older than me, right then he looked like a little boy who had lost his favorite toy, and was about to cry. Seeing him looking so sorrowful, was too much. After all, what harm WOULD a kiss do? (Yeah, I know ... I've been here before.) "Well, Okay ... but just one mind you, and nothing else. Any funny business this time, and I'm sending you back to your own bed." "Thanks, Sis." Oh God, my big brother can kiss good. Relenting a little, I opened my mouth and let him inside. For a second or two our tongues dueled, before I pushed him away. "There," I said. "One kiss ... now go to sleep." "Thanks, Sis." Mike rolled over on his back, and I could tell he actually tried to sleep ... for a while anyway. I couldn't sleep either. "Uh, Shauna?" "What NOW?" I wasn't really annoyed; just worked up from the kiss. "Can we do it again? Just once more? Please?" Oh what the heck. "C'mere, Big Brother." This time it was more than just a kiss. I felt Mike's body come over mine in the dark, and his big hand come to rest on my breasts (which were already aroused and sensitive) as he fastened his mouth on mine in a kiss that made the earlier one seem chaste and innocent. I was almost fainting with excitement ... shuddering with the repressed need and hot feelings in my body. I could feel my brother's prick, now an engorged and throbbing hardness against my thigh, poking at me. I knew I had to stop things before they went any further. "That's enough, Mike," I said; trying weakly to push him off me. "Please?" He replied, almost a whimper of repressed need. "Just a little more ... I promise." My brother's hand was almost unconsciously rubbing my right breast, as he looked at me with that pleading, puppydog look that I could hardly ever resist. "Just a little more?" "No!" I said firmly. "You know what will happen if we continue. You'll get more and more excited, until you want to put it inside me again ... and then who knows what will happen?" 1 Actually, we BOTH knew all too well what would happen ... it had happened way too often before. "Please? Just a little? I promise that's all. Besides, you like it too! I just want to feel it just a *little* more. You feel SO good, Shauna." I couldn't deny that. My whole body ached to feel more of my brother's body next to me, on me, and yes even IN me. Still, another kiss or two wouldn't hurt, I guess. I relaxed and agreed. "OK, but remember, just a little ... you promised." "Thank, Sis! You'll like it ... really!" I suddenly realized with shock that my brother thought I had agreed to let him put his prick in me again, not to kiss a little more! I was about to object, when I felt him slide between my legs; and the touch of his prick against my aching, needing, WANTING vagina was too much. Almost automatically I spread my legs and let my big brother slip inside me. I told myself that it HAD been my mistake ... and I HAD told him he could ... even if he had misunderstood me. Oh GOD, did that feel good. "Oh Mike," I moaned; giving my hips a bump and grind so he slid so satisfyingly all the way up inside me. "We shouldn't be doing this." "Uh, Unh, Uuuuhhhgnnh. Uh why not?" He asked. "I like it ... You like it too ... I know ... why shouldn't we?" "Because I might get *pregnant*, you dummy," I whispered fiercely. I didn't want my objections to wake up our parents. Who knows what they might do if they found their two children rutting like minks in the same bed. Especially since they didn't even know we were sleeping together. In spite of my objections, by this time my hips were rolling to meet my brother's frantic humps into me. "Remember, you promised, 'Just a little,'" I reminded him. "And we've already done more than just a little." "Uh, PLEASE Shauna ... just a little more ... it feels SO good!" Oh God, was my big brother right. His prick felt SO right inside my body ... as if it was made for this wonderful thing of filling my crack; throbbing and swelling and feeling SO good. Oh God ... swelling? Oh shit. Still, it was almost as hard for ME to stop as it was Mike. "Oh, OK ... just a little more," I heard myself say. "But don't cum in me. I don't want to get pregnant by my own brother." Mike took my agreement and ran away with it; humping madly into me until his pubic bone was banging against mine, while we rutted madly together; his prick sliding out until it almost disconnected; then sliding in until it filled me so full I could almost taste the precum and sperm leaking from the tip into my waiting fertility. Oh God ... I just HAD to make him stop before ... Oh God, that felt SOOOO good! "Please, Shauna ... Just a little bit. I want to feel what it's like ... just a little ... I promise I'll pull out after that, OK?" Somehow in the heat of passion I heard myself agreeing ... I would have agreed to have my head chopped off, if that would keep my big brother's prick sliding in and out of me ... I was close ... SOOOO close. "Well, Just a little," I said; frantically working my hips against his. 2 I felt the first cramp squeeze my body and his prick inside me. "Remember, you promised! I don't want to get pregnant." "Oooh, Thanks, Shauna I'll just squirt a little bit ... you'll see. Oh God, that feels good. Just a little more ... squeeze me just like that ... Oh God, I'm gonna ..." Only I beat him to it. With a wail it's a wonder didn't bring both parents running to our room to see who was murdering their little girl, I suddenly grabbed Mike around the chest with my arms, and around the hips with my legs, and started clamping and squeezing just as hard as I could while the knot grew and grew inside my belly until it burst. I was barely aware of Mike being taken along with me. "Shauna ... I'm going to cum ... Shauna! Oh God ... SHAUNA! Oh, OOOOH, Ooouuuoohhh. Oh God, that felt good." With each exclamation I felt my brother's prick leap and stretch inside me. They say you can't feel a man ejaculate inside you, but I didn't need to. The stretching and swelling of his wonderful penis inside my needing hole was SOOO nice, and scratching the itch I had been feeling all afternoon SOOO well, that even knowing Mike was ejaculating his potent sperm inside me in thick white incestuous gouts of baby-making seed, was more a turn-on that he liked me enough to plant that much spunk in my horny little tummy, than turn-off at the thought I might be getting pregnant with my own brother's baby right then. (OK ... I'll admit it ... even the thought of getting knobbed by my own brother was a turn- on, when I was getting royally fucked like that. The scary thrill just adding to the sheer overpowering intensity of my orgasm. Later, I knew I would feel guilty and scared. Right then though, the kinky knowledge that millions of Mike's potent little wrigglers were seeking my developing eggs was just making me cum that much harder!) I finally collapsed, panting harshly, while my big brother's groans of release finally died to pants; and his frantic thrusts to deposit his sperm as far up inside my tummy as he could, slowed down to just friendly cuddling, while his prick wilted; keeping his sperm bottled up inside me until one of us regained enough sanity to reach for the tissue we kept beside the bed. I knew that right then my open and receptive cervix was dipping into the obscene pool of thick white goo my brother had deposited in my body; sucking millions more of his potent sperm into my uterus where they would join the wrigglers he had deposited in my body earlier, in their frantic search for my ovaries and the eggs they contained. I was too relaxed and comfortable with my big brother on top of me to care. Eventually though, we had to pull apart. Mike is just too big for us to sleep comfortably with him on top of me. As we separated, I looked down at the smeary mess his cum had made of my crotch. Mike looked too. "Um ... I guess we goofed again," he finally said. "I guess we did," I agreed. There was no heat in the accusation I leveled at my brother. "You promised you'd only do it a little bit," I reminded him. "Sorry, I was going to pull out after the first squirt, but you wouldn't let me," Mike reminded me. Whether or not he COULD have pulled out, even if I had, was something I doubted. 3 "Um." That non-committal remark was all I could think of. I grabbed a tissue and stoppered up my leaking hole; then handed my brother one to wipe himself with. Mike watched me do this with some interest. "Uh, Shauna?" "Yes?" By now I was starting to feel the usual letdown and guilt about having sex with my own brother ... but not enough to make him go back to his own bed, either. It was SOOO nice to snuggle up with the man you loved after a bout of sex like that. "Uh ... could we do this again some time?" "Mike!" I made it plain that I thought we shouldn't have done it THIS time. Mike very sensibly shut up, and snuggled down to go to sleep. Somehow I knew though that by morning my big brother would probably be trying to do it to me again .... .... And I knew that once again I would probably let him. 4
