[MFF] The Voyeuristic Sibling: Part 1?

“Oh my god!” Lucy shouted into the pillow covering her face. Tightly pressed against her glowing face and heavy breathing through the soft tissue of her linens.

Lucy knew her sister had been in the house while I had made advances on her. Pulling the pillow tight onto her face as another wave of her orgasm crashed over her, pulsing through her body like a hot-summer night breeze, followed by the cool rush of ocean waves as I glid my tongue over her blooming labia.

This wasn’t like any other day, as normally, Lucy would wait until her sister had left the house until we had time to rush to take off our clothes and devour our bodies. Today was different. We hadn’t seen each other in a week due to work, and we both had settled not to touch ourselves when we were away. This was to help us build our lust – and build our lust it did.

The pillow on Lucy’s face made it hard to breathe, she had forgotten how hard she was pulling the pillow into her face as I lashed over her aching clitoris. I could feel my heart racing as I heard Lucy breathing hard into the fabric tightly to cover her agonizing screams as I caressed her with my lips.

I, too, was thinking about other people in the house; her sister, a few years younger than Lucy, surely must’ve felt the tension between Lucy and me when I arrived at their parent’s house. I had already had a hard-on when stepping on the doorstep and desperately covered the bulging tent of my manhood with my luggage. Whether anyone could hear us, I simply didn’t care.

Lucy’s thighs were tightly gripping my face, brushing against the rough stubbles of my beard. She was enveloping me with her warmth as I imagined intimately kissing Lucy in a hot passionate tongue filled kiss. Of course, I could only imagine what her face looked like under that plain-coloured pillow so tightly wrapped against her face. Replacing her tongue and lips with her clit and labia, I was enjoying the radiating heat of Lucy’s sex tightly pressed against my face.

I knew Lucy was close, very close now. I knew it didn’t take much to trigger one after the other wave of a crashing orgasm. Her pulsating walls were inducing warm radiation in my body – a deep level of satisfaction spread throughout that was inducing my body to store up more and more sexual energy in my groin.

Lucy was on the verge of another orgasm as I plunged my tongue across her clitoris, vigorously using the underpressure in my mouth to receive her swollen lust in my waiting mouth. “Yes, yeees, I’m comiiinnnngg” – I could hear her muffled shouts as her beautiful pale body heaved in front of me uncontrollably, giving rise to another mind-shattering orgasm of release. Lucy was completely lost in the orgasmic bliss and irreceptive to the sounds coming from the nearby closet.

I was not as insensitive and could hear a distinct fluid motion sound. As if someone was wiping a hard-to-remove stain on a large dish with a fluid-filled sponge. Repeatedly, fast, the sound was subtle, but it was there, coming from the closet. Were we alone in the room? It couldn’t be possible, Lucy’s parents were downstairs and her sister said she’d go to her room.

Lucy pulled the pillow to the side in one swift motion dragging the fine lacy fabric of her bed linens across the gentle marks of her face. Her lips dragged across the dry fabric in a desperate bid to catch a breath from the numerous peaks of repeated release she’d been longing for so desperately for the last few days. “Fuck, I needed that so badly”, she panted, sweat instantly pooling on her bare chest as she desperately gasped for air.

I instantly dive in between her legs to tease another round, but Lucy’s hands tightly grip my head and pull me up to catch a breath. “Please, I’m gonna be sore, and then we can’t have sex. And you know, I want to have sex,” she says in between heaving breaths piercing my lustful drunken eyes as I restrain myself and break our intimate touch.“I need to pee; I can’t hold it anymore,” Lucy says, rolling off the side of the bed. Her long slender legs buckling at the knees get up off the stained sheets covering her bed. Her feet barely provide the necessary support as her clitoris pulses between her legs. She dives forward to give me a deep kiss, her longing tongue penetrating my mouth as I would soon penetrate her inner core and probe my sore but pleasured face.

As soon as Lucy left the room, I got off my knees, noticing the small pool of pre-cum that had nestled between my legs. A small indicator of the huge pent-up load that was agglomerating in my tight and now aching balls. Curious as to what the noise could have been, I stumble towards the closet next to me. Not a meter away, the white wall built-in closet with sleeted furnishings surely let a bit of light from the room into the closet, but I could not make out what the source of the odd sounds had been.

I slowly slid open the door of the closet, ignoring the fact that clearly, this was invading a bit of Lucy’s privacy, but I did want to make sure we weren’t being watched or possible someone had broken into the house. As I uncover bedsheets, linens, towels, and a potpourri of dresses hanging in front of me, the smell of Lucy’s clothing fills my senses.

I immediately recognised some of the gorgeous dresses that I had taken off of or not removed from her from one of our date nights.

In addition to the flowery smell of Lucy’s perfume that covered the flowing contours of her dresses laid out in front of her, a pungent, musky odour filled my nose, similar to what I had smelled when I had just removed my nose from Lucy’s warm wet pulsating folds. A smell that clearly induced an immediate instinctive rush of fresh blood in my now softening member.

“Could this be…” Was the last thought I could just before a warm shadow wrapped over my fully erect and dripping member in one swift motion. The hot glowing heat of soft but tight tissue had fully engulfed my pulsating penis that had been anxiously waiting for Lucy’s return.

The first touch after a week of abstinence was not by Lucy’s terms. In the blink of a quickening eye, I stood in front of dresses, naked in Lucy’s room while being fully engulfed, my member disappearing into the bleak trembling unknown at the base of Lucy’s closet. Stupefied and overwhelmed by the sudden sensation, I tense up and stare to the base of my feet, where all but deep blue eyes staring back at me have replaced the sight of my leaking bare cock.

I was trapped in the trembling oral cavity of Lucy’s sister. My by now throbbing cock had no mind of its own. Did not know to distinguish between the hot love-filled mouth of my partner and this unexpected invasion. Lucy’s sister Maria, large and gazing eyes wide open, her lips firmly pressed where my cock conjoins with the rest of my body, fully enveloped my throbbing and tingling member. Frozen in place and desperately trying to process what was happening with my body, I look back at Mary. I feel her tongue caress the throbbing vein at the base of my penis.

The soft velvet covering Mary’s tongue was pressing forcefully against the spongy tissue surrounding the pipework covered in my swollen shaft. Fully laden with pre-cum and vigorously now dripping in the seemingly wanting throat of Lucy’s younger sister. Her eyes interlocked with mine told me one thing: “She knew exactly what she was doing”.

The force of Mary’s tongue pressing against the shaft and gliding up along the base of my pulsing cock was driving a tingling sensation from the tip to the base and deep into my swollen, heavy testicles. The cum I had been storing and producing was waiting to be released in the warm heated folds of Lucy’s innermost core. Here, they were at the entrance to an unknown void that would draw them out, wasted in the devouring depths of Lucy’s sister.

“Thunk, thunk, thunk” – I could hear footsteps across the hall. Lucy had finished her intermezzo and was coming back to the room. In a swift motion, Mary released me from her waiting mouth. The cool breeze of her breath covered the spit-covered shaft that was now dangling in front of her rosy face. Beneath her, I could now see what had caused the unfamiliar noise. A pool of wetness between her legs was indicative of the pleasure she had given herself as I had given her sister pleasure.“If you say anything now, it’ll look like you’ve been cheating on her with me. This never happened.” It was then that I realized that this was mutually assured destruction. She was right, if I didn’t want to risk my relationship with Lucy, I simply had to keep my mouth shut.

With a swift motion, Mary pushed me back and out of the closet and shut the door. My throbbing wet member just moments ago in the wanting folds of Lucy’s sister, now dangling desperately in the room. Glistening strands of Mary’s saliva dripping from the head of my rock-hard glans – “Fuck I’m already close to coming”, – I think as Lucy swiftly reenters the room.

In a long stride, she hurries towards the bed, removing her panties in a swift motion and throwing them at me. “What are you waiting for,” she says as she bounces off of the mattress, spinning onto her back. Her hair was flowing over her body, embedding her gently in the soft sheets of her bed.

Hesitating for a moment, I gathered my senses and tried to forget that Mary was surely now lying back against her sister’s clothes, enjoying the start of our lustful encounter that was about to happen.

Crawling up between Lucy’s soft thighs, I take her hands above her head, trying to refrain her from guiding me inside her. This was one of Lucy’s signature moves. She would usually take my shaft and slowly place it at her entrance allowing me to glide inside her without further ado.

I could still feel the cool breeze as I motioned through the room, meaning I was still moist from the encounter with her sister only moments before, who was now surely masturbating to the sight unfolding in front of her. I positioned my hips just at the right angle so I could easily guide my unfaithful saliva-covered shaft in Mary’s sister. My abs were desperately working to keep my body lifted above Lucy while not putting too much pressure on her hands as I pinned her against the mattress of the bed.

As I lower my hips, sinking my shaft into the heated velvet of Lucy’s waiting entrance, Lucy bites into my shoulder, not trying to make a noise as I stretch her walls around me. Easily I glide into her, feeling every rivet of her walls stretching and straining, engulfing my head and member in her most sacred core. She had no idea that at this very moment, it wasn’t just my own and her moisture conjoining us, but in between, a thin layer of foreign saliva had allowed us to embrace in this most intimate manner.

As my pubic comes to rest right above Lucy’s clitoris, I motion my hips to push even deeper, spreading Lucy open, resting my heavy aching sack that was now holding cramping balls on the verge of overflowing against the soft tissue against the lower part of Lucy’s toned rear.

A deep feeling of relief overcame us both at that moment as we had conjoined, our minds somewhere between the tongues of our mouths playing as my throbbing glans kissed the entrance to Lucy’s womb. “Please just come for me, baby”, Lucy whispered desperately into my ear as we both felt that the heat of our sex was making it inevitable for us further to prolong the oncoming storm of our impending orgasms.

I was torn between the now returned sounds of Mary vigorously stroking her clitoris and gushing sex in the closet and the slowly rising feeling of my approaching orgasm. Instinctively I moved Lucy so that our sex was in perfect view of the closet. I don’t know why I did it. Did I want to put on a show? Was I enjoying the thought of someone seeing the sexual acts happening, the impending rush of lust? Was I afraid that Mary could pressure me into further acts if I didn’t play along?

Regardless of the wall of thoughts I was processing, my mind was quickly turning back to the muscles lining the firey depths that were motioning to spill myself deep within her sister – no, no, no, in Lucy, in Lucy. I was inside Lucy. “Fuck”, I muffled into the sheets, desperately trying to focus on the sounds Lucy was now gnawing into my shoulder. And all I could think of was this encounter in the closet only moments before.

My balls were now fully drawn up and ready for their final release of what felt like the opening of a floodgate of cum that was being held back by terrible thoughts of guilt, lust and confusion. The tingling sensation of rising up along my sack, groin and my spine was enveloping my body as I felt the stream of my cum pouring from me into Lucy’s waiting cervix, contracting and drawing out spurt after spurt. My mind went blank with thoughts of Mary’s lips tightly wrapped around my shaft, my head deep on the verges of her throat, swallowing the life-giving seed I was pumping into her sister.

Pulse after pulse, with longer and longer pauses, delivered the release from me into Lucy’s waiting womb and spread warmth in her abdomen. She felt whole at that moment as my cum soaked inside her, unknowing of the thoughts, the worries, and the third person that had invaded her body, her own sister sitting only inches from her radiating glowing body that had just received the sperm of her lover.

Her legs tightly wrapped around my hips were pulling me in close as I enjoyed the feeling of togetherness as we lay in desperate exhaustion from the fulfilment.

As Lucy unwrapped her legs, I withdrew my glistening but still hard shaft from her tunnel. The bed sheets stained from the enormous load that both she and her sister had created were now half soaked into the mattress and the other pooling in Lucy’s abdomen.

It was in that lucid moment after Lucy had left the bed, making sure to avoid infection and hurrying off to the bathroom, that I remembered who had been watching all of this unfold. “She must still be in there”, – I thought as I stepped towards the closet and slid open the door that I had just passed through earlier.

Exhausted and heaving lay before me the tight, glowing body of Lucy’s younger sister. Vigorously stroking her clitoris, eyes tightly shut as I tower above her. My hand wandered down to my now again fully erect shaft. I tightly embraced the sensitive head in my hand, using Lucy’s cum to glide my hand quickly across. “What the fuck are you doing” – I tell myself – “this is your girlfriend’s sister”. My hand and body had taken on a life of their own.

The tingling sensation now spreading from my balls told me that my orgasm was quickly approaching at the unfolding sight laid out in front of me. I knew this was wrong, but my body did not care. Mary’s tight stomach was now heavily cramping from the approaching orgasm, her legs tightly enclosing her motioning hand. Short breaths emanate throughout the closet and drive the linens of Lucy’s dresses rustling in front of me as I stand above her sister on the verge of a mind-shattering second orgasm.

My knees buckle, and I reach out to lean against the back wall of my closet to support my weight as I stand above Mary, stroking my shaft towards her contracting abdomen. Her eyes open and look at me deeply in shock as the first drop of hot liquid dribbles from the head of my shaft and onto her stomach, right over her sex. My mind went blank as I shot pulse after pulse of my cum over Mary’s toned body while orgasming at the sight below me – Mary’s eyes now rolling back as her orgasm washes over her she rubs the incoming flood of semen showering her in her sisters closet and using it as an additional lubricant to enhance the sensation of the pressure along her pulsating clitoris.

As her orgasm throws itself through her body with my frame standing above her, she dives her sperm-covered slender fingers into her canal, pressing deeply against her g-spot, providing pressure against her throbbing sex. My mouth wide open as I breathe heavily, watching my cum leave my body into the unintended goblet that could bear my child just as well as my partner, whom I had just flooded with my seed moments ago.

I never agreed to this, but I did not care in the heat of the moment. All I could imagine was my cum spreading and pooling below me on Lucy’s sister while a few of my swimmers were introduced by Mary into her live-giving innermost sanctum. She was betraying her sister taking from her my most precious gift, and I could do nothing to stop her.

As the shooting and pulsating streams of cum subsided to a dribble and finally came to a full halt, Mary threw her head back on the floor, exhausted, panting and looking up at me. A sly smile was all I received as she slid the closet door back, and I knew that this was not the end but only the beginning.
