It was the night before my buxom teenage girlfriend Heather was due to leave to start her freshman year. She'd stayed the night at home with her parents trying to get everything together for her departure. It was a weekday so my
other kinda-girlfriend
Sam, a twenty-something beauty, was staying at her own apartment with her live-in but barely hanging-on boyfriend, Danny.
It was strange, being here alone in my own bed for the first time in awhile. Strange and sad because Heather was going away for several months. I made the best of it with my one small consolation: I luxuriated in the king-sized bed's extra space by stretching out spread-eagled and falling asleep like that.
I was awakened from a dead sleep by the slam of my bedroom door. I bolted upright to see a slender little body standing with her back to the door. It was Samantha. Her straight dark hair was down and she was wearing a... hmmm... she was wearing a "Go Lions!" t-shirt like the one from my old high school. There weren't any pants, at least none I could see. Her smooth, slender legs were bare. She had little white cotton socks on her feet.
I had just enough time to take this in before Sam scrunched her face up in frustration and demanded, "Hurry up and fuck me again before Mom and Dad get home."
"Huh?" was all I could say. I was still mostly asleep.
Sam walked to the foot of my bed, her face a perfect mask of annoyance. "What are you deaf? I said, 'hurry up and fuck me again before Mom and Dad get home!' Their plane just landed at the airport. They'll be back from their vacation in less than an hour. If you want to fuck me again before you go back to college and leave me here alone to deal with dumb high school shit, you need to do it now. So come on."
She whipped off the sheet I had covering my naked body.
My sleep-addled brain got traction and my heart skipped a few beats as I reached two conclusions. First, Sammie was crazy. Second, this was going to be fantastic.
"Nice!" she giggled, looking at my now-exposed nudity. "Did you know your little sister was going to sneak in here for one last fix?"
Sam slid into bed between my legs with her face by my groin. "Oh goody, I've never had it in my mouth when it's still all soft and cute. Usually by the time I get to it, you're all big and hard and scary."
With that, she swooped her mouth down to take my slowly rising erection into her mouth. She looked up at me, eyes sparkling, as she swirled her tongue and suckled. We both felt my cock grow harder
As I swelled to my full length and girth, she coughed and spat me out. She took me in her small hand and stroked me up and down slowly. ""I'm going to miss you so much when you go away
big brother
." She emphasized the significance of the last two words.
She continued stroking while her other hand pulled up her high school t-shirt. There were tiny cotton panties there beneath it with little pink and red hearts all over them. "Of course, parts of me will miss you more than others," she nibbled her lower lip as she circled her sex through the fabric.
She released me to slap against my own stomach. She hooked her thumbs into the waistband and quickly hauled her underwear down and off. She wiggled her eyebrows in a silly way and tossed them onto my chest
My breath caught when I saw her nude from the waist down. Sam had shaved her trademark little pubic triangle into the shape of a small heart that pointed downwards. Goddamn that was cute.
"I've loved you forever you know, big brother, " she confided as she rose onto her knees to straddle me.
"Since as far back as I can remember," she lowered herself until her smoothly-shaven labia came to rest warmly against the underside of my cock. She humped against me in a long pump of her hips that started with her back arched severely and ended with her hunched so far forward that my cock head dragged up the crack of her ass. I felt her wetness coat me.
"You used to push me on the swings," she bent down to kiss me. She didn't smell like her usual honey and sandalwood just then, she smelled sweeter. Simpler. Like cotton candy, I realized, as she reached beneath herself to take my shaft in her hand and center me on the hot opening of her vagina.
"You put band-aids on my scrapes when mom and dad weren't home." She teased us both by moving me away and rubbing the tip of my cock up and down her slit.
"You held me when my hamster died," she smiled, and wriggled my end against her clitoris for a few long moments. A little moan slipped from her lips.
"You teased me about my pigtails," she slowly re-centered us firmly at her hot opening again.
"You told me I was pretty when I needed to hear it - when I hit puberty and got gangly and awkward and I had to have braces," she rolled her hips, pressing down into me until I felt her lips gave way and my dick just breached the mouth of her pussy.
I held my breath and prayed. "This is not a dream. Not a dream. Not a dream."
"Oh yeah," Sam panted, "I love how it feels when it's just slipping inside me right in the beginning. You stretch me so good." She slowly forced herself down onto me, rocking her hips from side to side to swallow me up into the heat of her tiny body.
She leaned down to kiss me sweetly on the lips then laid herself flat along my body with her cheek resting on my shoulder. Her arms were flat against her sides. I hugged her small body, reaching down to cup one of her firm little buns in each hand. She kissed my neck and I felt her warm breath there. We didn't move for a few long moments. This was wonderful on so many levels.
Sam started us with a flick of her hips that slid me in and back out by maybe an inch.
"You really are a good brother. You drove me crazy sometimes but I realize that now." She laughed softly. "You told me I was ugly when I needed to hear that too - when I got pretty and vain and spent too much time looking in the mirror and obsessing over boys."
I cupped her little ass cheeks in one hand, moving the other up to stroke her back through the cotton t-shirt at the same time. I began to slowly fuck up and down into her.
Sam groaned as we rutted like this for a few minutes.
"I pictured you the first time I touched myself," she confided into my neck.
I rolled us over until she was beneath me, not breaking our connection. She looked up at me with huge, happy green eyes and lifted her spread legs high in the air. They continued higher still until her knees rose ridiculously past her own chest and brushed the bed on either side of her torso. She was folded in half beneath me.
She grinned and reached a hand down through her impossibly spread legs to play at her own clitoris. She giggled a little and continued talking, "I never told you this, but I watched you masturbate in the shower once. God, there was so much cum. "
I began to fuck her again. Gently at first. Then more roughly, Sam tilting her hips up to meet hungrily at each thrust.
"I still think about you coming all over the shower when my boyfriend fucks me. Sometimes I close my eyes and pretend it's you fucking me. "
Sam was deep in my head - jacked into my fantasies and feeding them jet fuel. All of my buttons were getting pushed at once. I was writhing in a mix of imagined urges. A righteous urge to protect - a taboo urge to fuck - a sister I never had but who was right here underneath me.
Sam's slid her hands up from her own crotch, one flung loosely on the bed above her head. The other grabbed the bottom hem of her t-shirt and pulled it up, way up, until it was bunched around her neck. It revealed the flat, tight, olive skin of her stomach and her bouncing, firm, B-cup breasts capped with hardened little light tan nipples.
"Hurry up, big brother," she urged, "I hear their car. It's pulling up the driveway. Come on me. Come all over your little slutty sister."
The automatic garage door downstairs started to open.
It was the last piece... a final thrill that fell into place. It was the thrill borne on the risk of getting caught. I hadn't told Sam about it because even I didn't realize it was lurking in the background. What happens if you get caught doing something so universally forbidden as fucking your sister? Sam had seen the potential for fear - seen it and looped it into our fantasy and then plucked it like a cello string.
My eyes widened and my mouth hung open. Dear lord this woman had a dark gift. I fucked her even harder.
"Come on big brother," Sam teased, cupping her boobs and pinching her own nipples gently, "blow your load all over my teenage tits. I can still make it back to my bedroom before they get upstairs." She plucked again at the cello string.
That did it. I barely had time jerk myself free from her pussy, then scramble up her body to straddle her hips as Sam let her legs fall back down to the bed. I couldn't even stroke myself fully once. I came, but not the normal sense: my dick, my balls, and my goddamn prostate had a syncopated seizure. My first stream of cum arced
over
Sam's head, it's trailing edge just catching the hair at her forehead. The next two struck her on the underside of her chin with a forceful, wet splat. Several more heavy spurts, I lost count at half a dozen as my head swam, fanned out across her chest and belly, bathing her body in cum.
