Helping Sis with Her House

"Well, I suppose I'll just have to make sure to make a very convincing argument for you to stay here," she nodded firmly. "But for now I hope you're just okay with sleeping in the same bed every night while you're here," she yawned a little. "Starting with tonight."

"I suppose that I could grant you that little concession," her yawn triggered one of my own. As I regained control over my jaw I could see her eyelids already drooping into sleep. My lips gave her a little peck upon the forehead before I allowed myself to shut my eyes and join her in slumber.

**********

The warmth of the afternoon sun spilling over us finally roused me from my slumber. For a few minutes I kept my eyes closed, shifting my body to curl a little closer to Karens' nude form. Fingers slid across her tight stomach as my groin came to snug against her rear, nestling my cock between her cheeks and pleasantly feeling them cause a little stir in the shaft. Sure it was wrong, at least illegal, and that gave me the feeling of being watched. For now I just couldn't give a damn, it felt right and the two loads I'd pumped into her swollen pussy had more than felt right. All in all this was already turning out to be the best damn Valentine's Day I'd had since I was a kid.

Eventually my eyes felt the need to open and admit to actually being awake. Against her hair I nuzzled my face, trying to prolong the dreamy feeling and fight off the feeling of being watched. The fact that I couldn't shake the feeling was starting to annoy me and interfere with my enjoyment of Karens' warm body pressed up against mine. My right eye cracked open, bringing a little wince at the bright sunlight. As it adjusted I let the lid crack open further and glance about the room to reassure myself that there wasn't anyone in the room. The only problem was the familiar figure of our mother standing in the doorway, her shoulder against the frame, arms crossed under her chest, and a little smile upon her lips.

I jumped back to the edge of the bed with a start, sliding out from underneath the sheets as I crashed to the exposed subflooring. When I managed to pull myself up to a sitting position, my head was filled with thoughts of how to start trying to explain what was going on. Certainly I wasn't ready for the sight that met my eyes, of my mother leaning over Karen, her lips pressed to my sisters in a more than motherly fashion.

"Couldn't wait, could you Karen?"

"Can you blame me mom? One thing just led to another and well, I couldn't help myself."

"No, can't say that I do and I suppose it's all fair in the end. After all, I did have you long before he did," over to me she glanced, lips curling into a soft smile. "Sorry, I didn't mean to spook you so much this morning. It was just a lovely sight to see, my two beloved children curled up together in their slumber, my little boy's cum dripping from his sister's swollen pussy. Your cock glistening with the sticky residue of your coitus. You have no idea how hard it was to resist the idea of cleaning you two off with my tongue while you slept."

"I...uh...WHAT!?" I'm fairly certain that people in China could hear my mind snap as it processed exactly what my mother had just said to me.

"Hunny, you just spent last night screwing your sister, not that I blame you or haven't done so myself, so please, at least restrain yourself a bit. After all you had to get the desire to do so from somewhere and that just happens to be your mother's side of the family. But that can be explained another time. All you need to know for now is that I'm very accepting of your very close relationship with Karen so long as you both are willing to share."

"Mom, you already know my view on that," Karen chimed in, leaning up to place a soft kiss upon the corner of Mom's lips then cuddling in against our mother like a long acquainted lover. She glanced over at me with a little grin, "Mom seduced me over Thanksgiving," she offered.

Slowly I got up on the bed, sitting at the edge, still not quite sure what to make of all of this but at least willing to listen in.

"Mmmm yes dear but it's also good to reinforce that fact to our young man here that sharing is caring in this family and that only we can provide for each other's needs without judgment." Her arm drifted around Karen's waist, coming to rest lightly upon her thigh. "And that so long that he understands that little fact he will never again need to worry about feeling alone and unwanted again, not to mention have all his physical desires tended to..." her voice drifted as her eyes settled.

I traced her line of sight and came to realize my cock was acting of its own accord, rising tall and proud at the mere thought of sharing Karen with my mother. There was so much of me that wanted to feel repulsed by the idea and yet after the night I'd just had, so much more of me that was highly attracted to the idea. "In for a penny, in for a pound," I whispered to myself, letting my eyes return to the view of my nude sister and still clothed mother before me. "I uh, think you might have the advantage here Mom, you're still clothed. Can't make the full decision without seeing everything I'm getting into without getting to see the bare package now can I?"

For the briefest of moments I saw surprise cross over Mom's face, then her lips curled upwards in a grin, revealing just the tips of her teeth. "Oh I most certainly agree," she stated before gently disengaging from Karen and getting up to her feet. Off came the sneakers, kicked to the side only to be followed moments later by her socks.

I moved more towards the center of the bed and smiled as Karen slipped towards me, setting against my side as my arm came to wrap around her figure. It just felt right to have her soft skin against mine and if it took including Mom, well, I wouldn't be losing any sleep over having two lovers. I felt the gentle touch of Karen as her fingers surrounded the shaft of my cock, gently squeezing me as we watched Mom perform her impromptu strip show.

Being sure to have our full attention, Mom stepped back from the bed and began to gyrate her hips as if she was dancing upon a stage. Her eyes closed as her hands came down to the bottom of her shirt and began to slowly lift it up. I'd seen her stomach before, during a phase where she liked 2-piece bathing suits, but it meant so much more now. It was easy to see where she'd been working out with the slender trim of her stomach. The stretch marks were there, those marks she always told us that she bore with pride, those marks that I suddenly felt the urge to kiss and love.

Her hips rhythmically swayed from side to side as her fingers undid the clasp of her jeans and slowly shimmied the denim down her legs, putting the sheer, pink panties on display. As they reached her knees, Mom turned around, bending over at the waist to show off her ass while sliding the pants down and off. One hand slid up the inside of her leg to catch the thin strip of cloth covering her sex, teasingly pulling it away from her flesh and giving the briefest of flashes of plump lips. "So how's that for getting to see the package?"

I was vaguely aware of Karen's fingers continuing to slowly stroke my cock, occasionally caressing the head with her thumb. My own hand had drifted to rest upon her pussy, feeling how wet Mom's striptease was making her. Gently I tapped her clit after the question came, "hmmmm. I dunno, thinking that perhaps I need just a little bit more revealed to make the choice clear." Teasingly I worked a finger into my sister's soaked hole, "agreed sis?"

"Uh huh," she moaned, "strip for him Mom. I wanna see you fuck him then let me suck your cum off of his cock."

Mom groaned as she listened to Karen, then flashed her a grin, "well now, wouldn't want to hold that up too much, would I?" Her arms slipped behind her back, fiddling with the clasp of her bra, then shrugged her shoulders forwards to let the material slide over them. Once loosened the bra dropped free, revealing her pink nipple capped breasts to my eyes.

She paused just a moment to let me drink in the sight before hooking her thumbs within the waistband of her panties and slowly working them down off her rear. Towards me she bent at the waist, shielding her sex from my view with her breasts, grinning teasingly at me. Up each leg rose as she stepped out of the panties, keeping her waist bent just a little bit longer. When she couldn't stand the teasing much more, Mom rose up, standing proudly to display her pink pussy with a heart shaved above it. She then parted her thighs and slide a hand down to put her pussy on display for me. "What do you think hunny? Look like a comfy place to put your big cock in? Do you want to show Mommy what a man you've become?"

I couldn't tear my eyes away from those pink, swollen lips of hers. Words failed me, but thankfully Karen had kept her mind about her. She gently pressed on my chest, guiding me to lay down, and waved Mom over. Karen's hand took a firm grasp of my shaft, holding me straight up as Mom straddled over my waist and brought her hips down towards mine. Against the slick lips she rubbed the head of my cock, leaning her face in to roll her tongue over Mom's clit and my cockhead. "Mmmm the taste of my baby brother and Mom in one lick. God I can't wait to see how good your cum is going to taste combined." Against Mom's wet hole she placed my cock, "all yours Mom!"

"Thanks dear," she grinned to Karen then licked her lips and turned to me, a hungry look in her eyes. "You have no idea how long I've been waiting to do this and how hard it was to not try to seduce you during Christmas. But now, it's all worth it." With that she began to let her hips fall, slowly working me in. When the head was firmly within her tight walls, Karen let go of my cock and moved back to snuggle against me, her head on me chest and eyes fixated on watching my cock penetrate our mom.

My eyes were wide watching her engulf my cock until her hips were resting against mine. She wiggled and adjusted her seat before leaning forwards and smiling down at my face. I couldn't help it, my arms went around her torso to hold her close and let me lock my lips with hers, with my mothers lips. Her tongue slipped into my mouth, seeking and eagerly greeted by my own tongue. When her hips began to rise and fall I moaned loudly into her mouth, lost in the feeling of fucking my own mother.

When the kiss broke I smiled, seeing Karen had latched her lips on one of mom's nipples. "Can't leave one unattended now, can we?" My mouth found the other nipple and my ears were greeted with Mom's loud moan and coo. Her hands found the backs of our heads, gently caressing them as she slowly rode my cock. At that moment I felt only one thing missing and let one of my hands drift back to Karen's sweet snatch, slipping a pair of fingers within her pussy, pumping them in rhythm with Mom's hips.

Mom leaned back to give herself more room to increase the speed and length of her thrusting. Against the bed I laid back and smiled to Karen, giving her enough to know what I wanted. Up she rose and moved to place her toned thighs alongside of my head then lowered that snatch to my waiting mouth. My tongue slipped out to begin lapping at her hard clit, lips wrapping around it to let me suck hard upon her sensitive nub.

I could feel sis move just before I heard the distinctive sounds of the two sharing a kiss over me. It was a heavenly feeling, Mom riding my cock and the taste of sis upon my tongue. My hands rested upon Karen's thighs, holding her down close to my mouth so my tongue could keep working her clit.

Mom was the first to cum, her pussy squeezing down tight on me as she ground her clit against my groin. I could feel Karen trembling as she bordered on orgasm herself, the excitement of both causing that familiar welling feeling within my balls. Perhaps sensing my impending orgasm, Mom bore down as tight as she could make herself, bouncing hard upon my cock. Seconds before I felt my body erupt into orgasm, Karen began to shake and moan with her own, holding tight to Mom while I filled our mother with my cum. Moments later the both crashed to the bed, curling up around me and sending the three of us into post orgasm slumber.

**********

I awoke with a start, glancing about the room and finding only Karen curled up against me. Her hand was very lightly stroking my quite swollen cock and a smiled played upon her face.

"Dreaming of Mom joining us, were you?"

"Ummm, yeah, I guess so," I said, a little sheepishly.

She just smiled a little wider, "I know, you moaned for her a couple of times. It was rather cute. Maybe for next Valentine's we should seduce her into our bed, but for now, or at least for today, I'd like to be your only Valentine."

I gave her a little kiss on the lips, "I think that could be arranged."

"Mmmm good, cause I've waited months for this and right now I need it bad." She moved to straddle my hips, quickly sliding my cock back inside of her. Towards me she leaned, arms resting alongside of me so she could press her lips against mine and mumble softly in the kiss, "happy Valentine's Day Brian. I love you, more than you could imagine."

My hands came up to her hips, sliding along her thighs and over her rear before they came to rest. "I love you too Karen and while I may not be able to imagine it, I'm quickly learning to appreciate it. Happy Valentine's Day."
