My Wife's Annoying Sister

"Hey... you've done this before, right?" I asked, suddenly worried, and Carrie looked back, shooting me a little guilty smile.

"Do my fingers count?" she asked, and I rolled my eyes.

I began to withdraw slowly, but she put a hand on my hips, stopping me.

"Just go slow, I can take it," she muttered, a determined look on her face, and I considered it for a moment before giving a little nod.

I eased a little further into her again and noted that the entry was considerable smoother the second time around, so I continued my advance, methodically, into her, slowly thrusting a few times every few inches until I was all the way in.

She whimpered a few times, and I paid attention to the signs.

When her hand tightened its grip around me, signalling to stop, I would pause, and give her a moment to breath.

I slowly made my way into her rear canal, but as I eventually bottomed out inside of her, Carrie's steady panting became less laboured and more excited, so I slowly began to thrust in and out of her.

"That's certainly something," Carrie mumbled in appreciation, her hands beginning to roam her body under her little red dress, and as I began to actually fuck her, though still slowly and gently, the wonderful sensation of being wrapped in the firm, tight embrace of her narrow anal passage quickly enthralled me.

The fact that I was fucking Carrie, my wife's sister and someone who I could barely stand ordinarily, seemed so surreal, and my hand instinctively went for her neck as our bodies began to draw more closely together.

"Mmn, yes. Choke me, Daddy," Carrie moaned, and I quickly tightened my grasp on her.

Ordinarily, I was little good at rough play.

Sherry complained about it all the time because I was never fully comfortable getting really rough with her, but as my fingers closed around Carrie's throat I suddenly felt the urge to vent some of the frustration that I had with her over the years.

"You like getting fucked in the ass like a bitch, huh," I asked, and as she gasped for air I released the hold just enough for her to answer.

"Yes baby, fuck my ass. Make me your bitch," she growled.

I pushed her head down, pressing her flat on the counter top as I began to pound into her with harder, deeper strokes, and a deep guttural grunt was now steadily coming from her every time I slammed into her ass, impaling her to the hilt.

"Mhn, faster," she suddenly called, "I think I'm gonna cum."

I paused for a second as grasped her by the back of her neck, then gripped her left leg which was over the countertop, and holding her firmly in place, I really began to pound her with conviction.

"Oh, baby, yes!" she cried out, and I went as fast as I could without throwing off my rhythm.

Her grunts quickly turned into screams, and she furrowed her brow and bit her lip till it bled, her hands grasping onto the countertop for dear life as the pleasure from her ass coursed throughout her body.

"Oh my god! Annhhhhh!" she finally cried, and I slowed the pace of our fucking, thrusting into her in full deliberate, strokes as her body began to shake and shudder under me.

"You alright?" I asked, a little concerned, and she nodded dumbly, her bangs matted to her forehead which was now drenched in sweat.

"Jesus. I think I just came," she mumbled, and I paused my thrusting to study her, a little perplexed.

"You think?" I asked, feeling a little offended, and she quickly shook her head, a smile on her lips.

"No, I definitely came. But it felt really fucking different," she explained, trying to catch her breath.

I withdrew my length almost all the way from her, then thrusted slowly back into her ass.

It was tight.

Tighter than any pussy that I'd ever fucked, and as I slowed the pace down and lengthened my strokes, the tight, compact tunnel stimulated the length of my shaft delightfully.

I felt like I could cum at any time, but I wanted to prolong the wonderful feeling for as long as I was able, and Carrie didn't seem to mind my continued fucking while she recovered from her anal orgasm.

"Did you cum?" Carrie asked, and as I shook my head a wicked smile appeared on her face.

She wriggled out from under me, and I let out a disappointed groan as my cock slipped from her wonderfully tight hole.

Carrie got off of the counter and I backed up into the fridge as she kneeled in front of me.

She stared deliberately up into my eyes as she wrapped her hand around my cock, stroking it a bit before leaning in to plant a deep, sucking kiss on the side of my rigid extension.

I watched with absolute fascination as she continued to stroke me, planting kisses all along the length of my cock until she finally positioned her mouth at my head, and after kissing the bulbous mushroom several times, she slowly and deliberately, swallowed my head, and took my cock as far into her throat as she could before her gag reflex kicked in.

"That is absolutely filthy," I muttered with appreciation, and she smiled wickedly, evidently turned on by the dirty deed.

Her blowjob was an absolute performance.

She could scarcely swallow two thirds of my full erect length, but her intense sucking, coupled with the way she stroked the base of my cock and worked it rhythmically as she sucked quickly sent me cascading over the edge.

"Ugh," I grunted, as I felt the pending eruption incoming.

Carrie's eyes went wide, but as she tried to withdraw, I grasped her head and held her firmly in place, thrusting into her mouth a little as rope after rope of my cum began to spew forth from my cock, directly into her throat.

She coughed a little as she swallowed the first few spurts, but she quickly regained composure and began to suck on me wantonly, desperately milking the rest of my seed from my balls.

Her eyes were a little teary, and as my cock slipped from her lips, she cleared her throat a few times, but there was a curiously devious smile still on her lips.

"Damn. Thick buttery cum just might be my new favourite Valentine's Day treat," she noted brightly, and I sighed.

"You have a weird fetish for butter," I noted, and she giggled.

"I do. I used to scoop up a little with my finger and eat it just like that all the time."

"How do you do that without getting fat?" I asked, and she shrugged as she replied:

"I dunno, but if I sucked your butter smeared cock as often as I'd like to, I'm sure I would."

"Maybe not every day, but an occasional treat mightn't hurt," I replied, and she smiled happily in agreement.

I got dressed and cleaned up the kitchen, then headed for a quick shower, but as I stepped out of the bathroom, Sherry, my wife, stood at the bedroom door, her hands folded.

"Two-thirty am shower?" she asked, a knowing smile on her lips, and I chuckled awkwardly in response.

"Heh- yeah, I guess."

"Please tell me it wasn't a prostitute?" she asked, and I quickly shook my head.

"Nope."

"Desperate Valentine's Day reject? Shit, at least tell me she was hot," she noted, before glancing past me into the bathroom.

"Wait, she's not in there is she?" she asked, and I shook my head again.

"No, no. And I dunno about hot, but she does share a significant portion of your genealogy."

"Wha- Carrie? You fucked Carrie?" she asked, her eyes wide with a mixture of shock and disbelief.

"Yep," I replied, walking over to the bed and retrieving my nightwear.

"How did that happen?" she continued, "I thought you two could barely stand each other."

"We can't, but apparently it doesn't get in the way of some kinky anal fucking," I replied, and she chuckled.

"Of course. The ass. The one thing she has on me," she commented, plopping down on the bed next to me.

"I'm too tired to shower... do you mind?" Sherry asked, and I shook my head as I finished getting dressed, and Sherry quickly stripped and climbed under the covers.

You're not angry, are you?" I asked, and she shook her head.

"Nah. I know you've been holding out all week, and I prefer that it was her than some prostitute. I kinda want details, but tomorrow. I'm too fucking tired to even be properly horny right now," she finished, with an exhausted sigh.

I took off the lights and climbed into bed with her, but I had scarcely even cuddled her properly when the first little snore came from her mouth.

The job sure demanded a lot from her.

Sometimes I wondered how she could do it.

If I missed even a little sleep I'd get miserable and cranky as fuck.

My mind began to wander as my own drowsiness kicked in.

I should do something special for her.

Maybe a threesome?

The kind she wants, I mean.

The thought made me shudder a little, but I knew she wanted it and it was the least I could do to repay her for being the amazing wife that she was.

I drifted off peacefully, but eventually I found myself waking up to a curious sensation.

What was that?

Was I having a wet dream?

It felt as if my cock was wrapped in a warm, wet embrace, and I twitched as what felt like a tongue ran wonderfully along the base of my shaft.

I felt my rod stiffening, and I rubbed my eyes as I tried to shrug off my drowsiness and get a handle on my surroundings.

"Sher?" I whispered, but the words scarcely left my lips when I noted that the spot to my left wasn't empty, and as I reached out I felt the definite form of my wife's sleeping body just beside me.

Then. That means...?

"Fuck, what're you doing?" I whispered, as my vision adjusted to the dim light, and I saw Carrie's face smiling wickedly up at me as she sucked me like a wanton slut.

She stopped sucking, but kept massaging my now stiffening cock.

"Valentine's Day isn't over yet," she whispered, "and I've always wanted to suck a guy off while he's sleeping next to his girlfriend."

"That's an awfully strange and specific fetish," I chided and she shrugged.

"Blame all the married men who keep chasing me down," she added, before taking my cock back into her mouth and really sucking on it.

I wanted to complain, but really, after just one orgasm, I still had a bit of pent up sexual frustration to release, so I let her continue, and as my hand once again strayed, brushing Sherry's sleeping form, I realized that being blown while my wife slept just next to me was indeed, an incredibly erotic feeling.

I put a hand on Carrie's head and forced her down, pushing my length deeper into her throat, and she began to suck furiously as I stifled a moan, shooting yet another load of copious cum down her throat.

Carrie held me in her mouth, her sucking restrained as she tried to keep all of my cum in her mouth, and as I slipped from her lips, she opened her mouth wide, proudly displaying to me the thick semen pooled within.

She held my gaze as she swallowed, then wiped her mouth before breaking into a satisfied grin.

"Doesn't taste the same without the butter," she whispered, and I sighed deeply, before shooting her a disapproving frown.

"You cannot make a habit of this," I chastised her, and she nodded dismissively.

"I'm serious. Sherry will slit your throat in your sleep," I continued.

"It could be worth it though," she replied with a wink, and I rolled my eyes as she turned and made her way to the door, but as she got there, she turned back to shoot me a playful smirk.

"Happy Valentine's Day," she called, a bright expression on her face, and I chuckled a little and gave her a wave as she smiled at me one more time before turning and heading happily out the door.

Happy Valentine's Day indeed, I thought to myself, as I snuggled up to my wife and quickly drifted back off to sleep.

The end!
