Sister to the Rescue Ch. 06

A perverse thought occurred. It was wrong. Just wrong. Not something I would do except in fantasy.

Except that now...I could do anything.

I turned to my sister.

"Mandy? You like playing at being a Lezzie, don't you?"

Her eyes widened. "Y...yes John?"

"Would you do this...for me?"

I hooked my legs between Mom's thighs and started to spread them apart. Trying in vain to close them, Mom reacted, voice quavering.

"John? Don't make her do this..."

I almost caved at that, but then I thought about how she had teased me for days in this sexy nightie, the same one now flopped underneath her on the bed.

"Mandy?" I said, flicking my eyes in the direction I wanted. I wondered - would my sister really do this? My hope lay in the sleep-overs she had enjoyed with her friend Anna. And her confessing to me that she had hid from her friend how much she had been turned on. The truth I had in turn hid from my sister was how aroused I had been by the image of the two girls together. Would she be willing to indulge me?

Her eyes shone back at me, wordless. Then her tongue came out and flicked her lips, moistening them.

"Y...yes brother. I do like to be a Lezzie..."

A primal part of my male brain exalted as I watched my little sister kneel obediently before Mommy's legs, give me a long final look for approval, and then ease her delicate face down between Mom's curved thighs. I could visualize my mother's open sex mirrored in Mandy's dilated eyes. A moment's pause - during which Mom continued to plead weakly in resistance - and then she licked the wet labia, and I knew exactly what she was tasting - the pungent earthiness at the core of Mom's need.

"Ohhh, oh, Mandy!" Mom's pleading tone changed instantly into shocked surprise at her own aroused response.

I turned my attention back to stroking her heavy breasts.

"That's right, Mom. You love it, don't you? Thank her. I want you to thank her."

Mom's mouth moved but no words came out. I tweaked a nipple between my fingers. Finally she obeyed my newly confident and sex-crazed dominance.

"Th...thank you, Mandy."

"What are you thanking her for, Mom?"

"I...I"

"Say it..."

"Oh, Mandy, thank you for licking Mommy's pussy..."

That wicked, primal part of me swelled all the more to hear such raw words from her mouth. The woman who had told us so many times to watch our language - here she was, losing any pretense of politeness to her own lust.

Meanwhile my sister was diving in deep before coming back up for air. Mom was losing inhibition, lifting her hips to rub her slit up and down her daughter's face. I could tell that they could both go for the completion, but for once I was enjoying being in control.

"Ok, Mandy, enough for now."

"Nooooo!" both wailed at the same moment, but I gently took Mandy's long hair in my grip and eased her up. I revelled in the sight of the sweet girlish face that I adored - soaking wet with our Mom's heavy juice.

I repositioned myself above Mom, spreading her legs with mine, my cock angling on its own volition directly at her sopping crotch. I was drunk on control.

"What is it you want?"

"Please? John?" she whimpered.

I softened my tone, stroking a cheek with my finger. "Just...just say it Mom. Rather than being teased, I wanna hear it for once."

"Oh John, darling!" My Mom's voice broke. "Please...please just fuck me."

For some reason, the moment shocked me. How had it come to this? Me, her loving and loyal son. Forcing her to beg for sex. Not just sex. Incest. But the knowledge that I was being so wicked didn't change my desire. I wanted her more than ever. And she sure wanted me. If her words hadn't been proof enough, the pungent scent of her frustrated arousal flooded out into the room.

My cock found her entry and, unlike my sister's, easily slid up to the hilt. Her whole body pulsed to grasp hold of me. She was beyond words. I pressed my chest forward, parting her bosom, until my pecs were hard against her breastbone, the curves of her breasts fully embracing me. I marvelled in how different she was than her daughter, and yet, when I kissed Mom full on the mouth, I felt the echoes between the two tastes. Mother and daughter.

I was overwhelmed with sensation, and yet a limbic part of my brain couldn't stop chanting the news. I was fucking my Mom. With my sister - even though I had known it was taboo - it had felt strangely innocent. Now, my hips started to pound with the joyful pleasure of such raw sinfulness. It was wrong, wrong, wrong, but fuck, I didn't just harbor a guilty desire for her, I didn't just let myself in a moment of weakness fantasize about her...I was going to have her! With my arms I pulled her in closer to me so I could take her more firmly. I rejoiced in how she writhed and moaned in my grasp. This is my sister, I suddenly thought. This is my sister grown up and ready for full on fucking.

Nothing could contain me. I pummeled Mom with my hard cock, even as I cradled her lovingly in my arms. My mouth was on hers, and I was delighted when her tongue rose up, doing all she could to penetrate me in return. She was as out of control as me. We were pawing each other and rutting like animals in heat.

"Oh yes," my sister's sweet voice called over both of us. "Do it, do it! You are both fantastic!"

When Mom came, quivering and crying out full volume, I ejaculated so hard I pretty much knocked myself out.

When I came to, I felt the small fingers of my sister stroking along my back and thighs. I eased myself off Mom and laid beside her panting body. It was clear that she had also spent herself in the orgasm. Mandy's hand found its way across my chest, palming me with love.

"Mom?" she said softly. "Can I use your phone?"

"What?" came her drugged voice. "Why?"

"I want to text your friend Sasha. Tell her that she needs to get over here now. Make sure you still get the Lezzie sleep-over that you deserve."

"Oh, sweetie!" Mom was making an obvious effort to pull herself together. She started to pull on the sleeves of her nightie, and then seemed to change her mind, turning to me, still naked, and smiling weakly.

"Wow, John." She reached up and kissed me on the cheek. "What can I say? I guess I'm glad my son can still surprise me."

I was nonplussed, not sure how to answer, even though I was deeply reassured by her tone. We were clearly both aware of how her bare breasts grazed against my chest but Mom did nothing to avoid the warmth of the mutual touch. Then she continued to pull on the nightie, clumsy in her post-orgasmic state.

"Thanks, Mandy, but...how do you young people say it now? I got this. I think it's best if I text Sasha myself. No, don't worry. I'm all in favor of your agenda. And now, I really am going to leave you two alone..."

Once there was just my little sister and me in Mom and Dad's bed, she turned to me, and said in a falsetto voice -

"Wow, John. What can I say? I guess I'm glad my brother can still surprise me!"

I batted at her arm, missing and striking one of her small breasts with my hand. She collapsed in giggles. But once she recovered, she gazed at me with genuine affection.

"Whatever. You are still my first. And that's what matters to me."

"Oh Sis. I know you may not get it. But in many ways...frankly, you are my first too."

Mandy's brow narrowed into a puzzled frown, and then, as she absorbed my words, she lunged at me with a delighted smile.

"I love you, Bro!"
