Every sane part of me knew it was past time to stop, but another voice was telling me to relax… enjoy. The grass said it, too. Madly I clutched for some straw of reassurance. Yes, Janey was a virgin. There couldn't be any possibility of something happening unless I actually did it myself. No danger at all. Let my nympho sister have a good time and then shoo her back upstairs to bed. It was all completely crazy anyway.
She tilted her crotch so the juice-soaked head of my cock slipped along the bottom of her gash. Then she pressed the other way so it would slide up over her clitoris. The hot little knot of flesh felt fantastic against my sensitive cocktip.
"Ohhhhh, I like that!" Janey breathed. Then she kissed my shoulder wetly. Her hair hung down, tickling my neck. I could feel its damp end and smiled. Once more she made her ass work so my cock gouged along the depths of her gash. But this time she hunched lower. With a squishy little thump, my honey-slick knob slipped into a deeper place and stayed them. Janey froze for a second, eyes wide. Her rapid little pants of breath smelled like bubble gum and ambrosia.
"That's really f-f-far out!"
I caressed her satiny ass with both hands, letting myself go a little more. Enjoying what the grass was letting me feel. Enjoying a girl playing over me. The fact that it was my sister seemed kind of blurry and far away. But I hadn't really done anything bad… yet.
"Ross, I feel so weird down there. All itchy and hot!"
I couldn't even talk now. It felt itchy all right. The whale head of my cock was coated with her sex butter and when she rolled her hips, the tight little beginning of her hole made a teasing friction that started my balls to aching. Yeah, I was sure now that my cock was pressing against the start of her cunt. But she was so small, and her cherry was there, too, to block the way. I relaxed some again, moving my own hips a little to make it feel better. Janey had pushed herself up, straightening her skinny arms to push back harder. The meat of her ass quivered under my fingers as she worked it up and down.
"Wow, I feel like I do when I rub myself!" she gasped, arching and humping her back as she kept the steady pressure backward. When Janey put one hand back between her thighs and clutched my cock to keep it from slipping to the side, I sensed things were getting dangerous. But it felt so damned good! Her email, strong fingers clutched around the shaft frantically, holding it firmly against her spread pussy as she tossed her hips faster. It felt too tight around my knob. Like the skin was being stripped back. Janey's eyes had a glazed, far-off look as she labored, a line of drool slipped down her chin.
"Oh, God, this is fun!" she sighed, hardly able to say the words. I wondered if things were getting away from me. The tightness was almost painful, but painful in a way that made me want more pain. My fingers were pressed into the flesh of her hips and waist, helping her push back. And in the nest instant the tight circle of cunt muscles surrounding my knob opened slightly and hot juice was touching my shaft behind the crown. My prick was too deep. Something was wrong.
"Rossss… Ohhhhhh!" Janey plunged her ass again and more of my cock was going up into her hole.
Knowing I had to stop, I started to push Janey over on her side, I could pull our bodies back apart, but she opened her spit-wet lips again and kissed me hungrily on the mouth. It was the turning point, I guess, because I grasped her small hips firmly and brought mine up hard from the mattress. Janey gave a choking gasp through the kiss and I rolled her savagely onto her back. I felt her legs flail the air as I fucked my ass under again and again. Her tight little pussy stretched and opened around the throbbing crown of my prick, wetting it with more love sap. A sharp heel raked down my back and then I felt her other slender leg hug the cheeks of my ass hard as I speared deeper into her cunt.
"Jesus, Ross! Oh, Jesus Christ!"
I kissed her then, making her take my tongue in the back of her throat. When I took my mouth away, her cheeks and chin were smeared with hot spit. Her hands clutched my back. Her cuntlips sucked and clasped at the thickness of my prick shaft. The way it felt was like nothing I'd ever dreamed of. Messing around with Bonnie Gordon with a rubber on hadn't even come close to this. Janey's firm little body squirmed and twisted under me as she moaned with the passion of our fucking. I plowed deep into her tight snatch and pulled back slow, breath shuddering with the ecstatic friction of her oily hole. It was so hot… so wet and tight. Janey flopped her head back and forth on the pillow, hair snapping against the sheet.
"Ross… I'm gonna come… love you… Rossssss!" I tried to kiss her, but she sank her teeth into my cheek, and then nipped at my chin. Her long lashes fluttered wildly against my neck. Then her ass gave a sharp jerk, then another one. Janey made a gurgling sound from deep in her throat and went limp. I still had a little ways to go myself and was trying to hold onto the thin edge of sanity long enough to keep from coming inside my own sister's cunt. It would be hard to stop but I had to try.
"Ohhh, Ross, it was great! But… but… it still feels wonderful down there! Oh, God, keep fucking me! Please, Ross! Keep fucking me!"
Janey pushed her legs down beside mine and hugged my thighs with hers. Her mouth looked bruised and her eyes were dark around the lids. The moon made her lips glisten and I felt the will power slipping away as I opened my own mouth and covered hers gently. She whined and sucked my tongue ravenously. Under my body I could feel the hardness of her pubic bone and the angular sharpness of her immature hips. She was starting to hump again, not as wildly as before but with a sure, rocking motion. Her fingers tangled in my hair, pulling our mouths harder together. Then she twisted her face to the side and gave a trembling shudder.
"It's starting all over! I can do it again, Ross! Oh, God, I can do it again!"
Our sex organs made a sticky, slick sound as Janey's cunt seeped out more pussy butter to ease the friction. When I pulled my cock slowly back, her ass pitched from the bed and bounced wildly on the mattress as if she wanted me to hurry and fill her cunt with my prick again.
"It hurts where you're stretching me. But I don't care!"
This time when we kissed it was a tender, teasing caress. Janey gave me the point of her tongue to suck, and when I had it deep in my mouth, she fluttered it feverishly and took it away. I gave a groan and tried to find it again, but my sister cooed and turned her face sideways on the pillow. I sucked the lobe of her ear between my teeth and nibbled until Janey's breath was husky and hard. Her bunching under me grew wilder than the first time she'd gone over the top. Now I could feel her nails gouging at my ass.
"Are you all the way in?" she asked.
"God, yes! I can feel something way inside you."
Janey humped her ass up from the mattress to let my dick slip even deeper into her grasping hole. "Yes. Oh, yes, I can feel you there!"
Suddenly she brought her legs up again, parting her knees so that her cuntlips parted back completely. The hilt of my cock was soaked, too, with her juice and as we tossed and plunged, the juicy sound of our fucking pew even louder. Janey dug her heels into the bed, grinding her ass in circles under me.
"Your cock's so big! It's pulling my clit every time you kick me!"
I'd been hoping I could hold on. Hoping I could stop. She was starting to gasp convulsively and I knew from the first time that she was about to explode again. I even tried keeping completely still, but my sister only writhed and jerked all the harder, shaving her clasping cunt down over my cock shaft and milking it back. Down and back, faster and faster she humped as she smeared wet kisses across my cheeks and mouth. The fire of no return filled my prick. My balls pulsed. Janey was heaving us both up from the bed now as the delirious spasms swept through her body.
