Sneaky Sister In Law 3[MF][Str8][reluc][cheating][squirting]

The events of the family dinner at my in-laws made me feel so guilty that I avoided my sister in law for weeks. I told me wife that I would watch the kids while she went out and did everything she needed or wanted to do, I declined family outings and dinners, and if Cari came to pick up my wife I made sure I was locked away in the bedroom until they had left. I did everything I could to avoid seeing her and I made sure I would never be left alone with her if I could help it.

This all was going fine until I was sitting in my office one day finishing up some paperwork when my assistant told me I had a visiter. There she was, standing in my office doorway wearing a baby blue summer dress that came just down to her knees. Her cleavage was pushed up and she had on a long gold chain that hung down between her breasts. She wore a pair of white strappy sandals and her legs were smooth and tanned. Her short, red hair was tucked behind a white fabric headband adorned with a large floppy bow. Her eyes were lined in thin black makeup and her lips were painted a glossy pink.

She smiled at me and took a slow, teasing step into my office. I sat silently behind my desk as she shut the door behind her.

“Wh-what the hell are you doing here? This is not ok, Cari.” I protested as she turned the rod that closed my blinds, never taking her eyes off of me. “Listen, what happened at dinner was ridiculous. You can’t just do shit like that to me! It’s so inappropriate and wrong and disgusting! I mean, this is just wrong, Cari. You did that without my consent and it won’t happen again. You can’t ever tell Haley about this and whatever this sick thing you think is going on between us is, it’s over.” I looked down at my paperwork and hoped that she would take the rejection and leave on her own. She had other ideas.

“Hmm, you think it’s not going to happen again?” She asked condescendingly as she walked slowly around my desk. “So, I guess that means that you won’t take me right here, right now, on this desk?” Cari swiped the papers in front of me onto the floor and hopped up onto the desk.

“What the fuck Cari! What do you think you’re doing? I’m calling security and you’re leaving right now. I have a meeting in 10 minutes, this is over.” I reached for my phone and Cari slammed her hand down on top of mine.

“You think that will be the end of it? You think you can explain to your office security team why your sister in law is spread eagle in your desk? Hmmm, I hope nobody in your office mentions this to Haley.” She taunted, slowly spreading her legs and propping her heels up on my chair. Her thighs were warm and pressed against my hips. I looked down at her voluptuous body, her legs almost wrapped completely around me and her breasts pushed up as she leaned back on my desk.

“F-fine. Just…just leave now and we can forget everything that has happened these last couple of months.” I gave her one last chance to leave and forget all about this. She didn’t agree.

“Hmm. Or, this could play out another way.” She bit her lip and wrapped her ankles around my hips, pulling me close until my crotch pressed against her pelvis. “You do exactly what I say, or I yell for your assistant and she walks in here to see me half naked on your desk.” With one swift motion she pulled her breasts from her dress and I was faced once again with her firm and perky nipples.

The first time I had seen her naked I was in shock and able to close her coat and send her on her way. This time she was not so easy to ignore. I was being held close to her warm body, unable to escape by threat of being exposed. For a single weak moment I reached up and held her supple breast in my hand, squeezing and massaging her with a long, nervous sigh. After a few seconds I snapped back to reality and released her smooth breast.

“Fuck, Cari, what the fuck are you trying to do! Why are you doing this to me?” I asked with a catch in my throat and a growing bulge in my pants. She grinned and giggled, sitting up straight and tucking her hands into my back pockets.

“Because, honey. You deserve to get your rocks off and my prude sister doesn’t know how to please a man. Besides, I love watching you squirm and you know deep down you want all of this.” I felt a bead of sweat drip down my temple and her warm breath on my neck made me tingle.

“What do you want?” I asked, my eyes closed and my teeth clenched.

“Touch me. Feel these tits and just try and tell me they’re not more perfect than my sisters could ever be.” She squeezed her breasts together and pushed them up toward my face. I could smell the lavender and vanilla on her skin and I shivered as I looked down at her firm chest. I took a deep breath in, hesitant to give in to her sick demands, but I couldn’t let my wife find out about what’s been going on.

I reached up and reluctantly cupped her ample bosom. My palms pressed against her hard nipples and my fingers grasped her supple tissue. She was right. Haley’s tits were nothing compared to hers. These were soft and smooth, substantial in size but still so supple. I sunk into them, groping and fondling her like a horny teenager with my mouth open and eyes fixated on her.

“Fuck.” I mumbled. She let out a subtle chuckle and grinned at me, knowing that she got her way and I was entranced by her perfect young body.

“That’s right.” She whispered, spreading her legs and propping her feet up wide on my desk. “Now touch me, right here.” She grabbed my left hand and slid it down her body until I felt the heat radiating off of her loins.

“Shit, you-you’re so hot. That body…” I felt like an idiot stumbling over my words and succumbing to her devilish charms. “I-I can’t do this Cari, I’m sorry. There’s nothing you can do to-“ she cut my off by pushing my hand suddenly into her crotch. That was it. Her moist, shaven mound had me and I fell into her trap.

“There we go, baby.” She cooed. Her smooth pussy lips felt like heaven under my palm and I slipped my index finger between them, feeling how wet and ready she was.

“J-just tell me what you want me to do Cari.” I submitted. She smiled wide and bit her lip as she had finally won.

“Finger this cunt and make me cum so hard you can taste my juices all over your face. I’m going to scream for you like Haley never does.” Her voice was gentle and seductive and I thought one last time about what would happen if I resisted.

I could see in her eyes that she would do whatever it took to get me, but it was so hard to give in to her crazy demands. She gave me one last dominating expression and her next words took away all doubt.

“Oh dear! But, I’m your sister in law!” She shouted almost loud enough for my assistant to hear her. She wasn’t playing, she would ruin me. I had no choice.

I immediately and almost excitedly slid my index finger into her surprisingly tight cunt. I wasted no time. I penetrated her hard and fast, furiously fingerbanging her as my eyes never strayed from hers. She stared into my eyes with a sense of satisfaction and her jaw dropped at my skilled come-hither motion. I couldn’t remember the last time I had my fingers inside my wife, and even when we were more active, her pussy never felt as tight and moist as Cari’s.

I groped her tits, switching back and forth and feeling her beautiful body as much as I could. I slammed my hand into her like my life depended on it, determined to make her moan so I could finally hear the sensual sounds of a woman. I gritted my teeth, knowing that I had started this just to keep my dirty dining room secret from being discovered, but I realized that now that it was happening, I wanted it more than I could have imagined.

“Oh, fuck. Cari, you get so much wetter than Haley ever did. You really want me don’t you? You want this.” I whimpered, feeling my erection leaking into my boxers as I ravished her eager body.

“Mmm I knew you wanted this.” She moaned. “I knew you’d been needing to feel this young little cunt around your fingers. Ooh, yes baby! You pound that sweet little pussy and make me cum like a real man.” She groaned and gasped at my skill and soon I didn’t even care that she was starting to get louder. “Mmm, you can say it baby, say it! Or I’ll scream so loud your assistant will walk in here and see you wrist deep in your sister in laws cooch!”

“I-I, ok! I want it!” I cried out, fingering her harder and faster and looking into her eyes as I hammered into her like a machine. “I fucking want that tight little body and I want to make you cum like a fucking fountain! Come on Cari, give it to me, cum hard for me!”

I gave in. All of the guilt and shame was overcome by my need to pleasure this beautiful woman. My wife wasn’t a sexual being like her sister and I wanted so badly to make her orgasm all over my desk. I knew it was wrong, I never wanted this to happen, but now that I could feel her dripping cunt squeezing around my finger I couldn’t help but want to see her climax. I added a finger, massaging her g-spot and rubbing her clit with my thumb as I leaned in and took her left nipple into my mouth. I sucked on her delicious tip and shook my hand in a quick vibration to stimulate her sensitive clit.

She moaned loud in my ear and I could feel her muscles contract. She wrapped her arms around me, her long fingernails digging into my back and her hips bucking against my palm. I felt myself throb in my pants and the front of my boxers was slick with precum. I released her nipple and lifted my head, my face pressed against her trembling cheek. Her breath was hot on my neck and her whimpers and moans echoed in my ear.

“Yes, yes baby! There it is!” She cried. Suddenly, her body shook and convulsed, her moans turned into a high pitched sigh and her pussy squirted like a fire hydrant. She came all over my hand and her juicy discharge dripped down onto my desk. Her enthusiastic climax made me whimper and I looked into her eyes as she giggled.

“Oh, my God. H-Haley never cums like that.” I admitted. She smiled at me knowingly.

“Don’t you forget that, honey.” She said, pulling my fingers from her gushing hole.

She lifted my hand and sucked the juiced off of my fingers, never breaking eye contact. I shuttered, my engorged manhood trying to break out of my pants. She gave me a wink and pushed me backward, hopping off of my now soaked desk. She straightened her skirt and tucked her breasts back into her dress, her thighs still glistening with vaginal juices.

“Now, better straighten yourself up before your meeting. Wouldn’t want anyone to be suspicious.” She turned on her heel and opened the door, giving me a friendly wave as she walked out of my office.

I stood behind my desk, dumbstruck and dripping with her delicious moisture. After a moment of cleaning myself up and trying to calm my raging erection, I went on my way to my meeting. My mind raced and I knew, this wasn’t over.
