The Sitter Ch. 03

My distended member throbbed hungrily. Heavy with need, it angled away from my belly and aimed itself at Mom's crotch.

Without conscious thought, I stepped forward. The head of my cock butted up against the lips of Mom's pussy, and she opened up to let me inside. With a quick thrust, I buried myself to the hilt, Mom's plush ass thumping deliciously against my stomach. I wrapped my hands around Mom's trim waist and began to slowly fuck her. I shivered when I felt Karen's mouth wrapped lightly around my balls and began to suck. My swollen cock throbbed inside Mom in response, and when I withdrew from her, Karen licked the exposed length of my cock before I drove it home once more. When I did, Karen transferred her mouth to my balls once more. The pattern repeated itself; Mom's mouth on Karen's pussy, my cock within Mom's, and Karen teasing me with her lips and tongue and teeth.

It wasn't long before I was driving more and more quickly into Mom, and she enthusiastically fucked back at me, matching me thrust for thrust. Karen couldn't match our tempo, so she ignored my thrusts and settled on alternately sucking on my right and left nut. I could almost feel my balls filling with cum, and it felt to me like my cock was gaining an inch with each thrust. I didn't think I could last, and I couldn't.

Within ten minutes, my balls contracted, my cock expanded, and I felt the cum surge up through the length of my rod. Karen felt it too. As I withdrew, preparing to slam myself deep into Mom's cunt and unleash a torrent of cum, Karen wrapped a slim hand around my length and dragged it free of the sweet confinement of Mom's cunt. Instead, she angled my cock downward, and enveloped the tip in her mouth.

That was it.

I braced my palms against the small of Mom's back, and she looked up from Karen's cunt, giving me a lust glazed look over her shoulder. My cock bucked and heaved, jetting wads of cum into Karen's mouth. I watched her throat work greedily to accept my gift, swallowing a prodigious load that didn't seem to want to stop. I came and came, and Karen took it all, never spilling a drop. At last she released me and I lurched backward on unsteady legs. Karen coughed, gurgled, and sucked in a deep, deep breath.

"Mmm, mmm, good," she said. Karen and Mom started giggling, and Mom maneuvered herself so that she was laying on top of Karen, tits to tits, pussy to pussy. I didn't quite get the joke, and didn't have the breath to share in it in any case. I collapsed to the floor on my haunches and tried to regain my equilibrium. It did not return with any amount of speed, but Mom and Karen were quite capable of amusing one another while they waited.

That was another night we ended up in the Jacuzzi, washing sweat and cum from our bodies with steaming water, even as we fucked again and again.

Not that everything was sweetness and light, however. Mom and Karen both encouraged me to join the swim team, and I made it on the team pretty easily. My hikes, biking, and sexual work-outs ensured that I was in excellent shape for a nebbish kind of kid, and I did well on the team. There was a girl, a senior like me, named Melonie Driscoll. We sort of hit it off, and started hanging out together. Mom saw it as a good sign, but then no matter how involved we got in the bedroom, Mom always considered it recreational. Karen, though, got a little temperamental whenever I mentioned Melonie, or did anything with her. I didn't really understand what was going on; I mean, my Mom was telling me it was cool, and I was totally in love with Karen besides. I thought she knew that, I thought she realized Melonie was just my friend. But like I said before, love isn't exactly rational, is it?

So one day Karen blew up at me and took off in her car, leaving me dumbfounded and speechless in the living room. I'd never had a girlfriend before, let alone a live-in lover, and I had no idea what I was doing. So I went to Mom.

"I thought I heard some yelling down there," she said when I came into her room. "What's wrong?" She was in bed, with the covers up against her chest, a brief in her hand. She pulled her glasses off to regard me as I approached.

"Karen's upset because I spend so much time with Mel. But you tell me to spend more time with her." I sat down on the edge of Mom's bed. "I'm a little confused."

Mom frowned. "Hmmm," she said thoughtfully. "Maybe I've steered you wrong on this one, sweetie. I thought spending time with a girl your own age would be good for you. I don't know, I guess I thought that Karen saw our arrangement the same way I do." She reached over and patted me on the arm. "Which I mean in the nicest possible way, sweetie. You fuck me like no one has before, but I think you understand when I tell you I prefer to stay objective about the whole thing. I want you to grow up healthy and move out and get married and give me grandchildren eventually, and you won't be doing any of that if you and I get too involved. But Karen doesn't have that worry. . . and she's a lot younger than I am, and less sure of herself. I don't know why I didn't see it sooner.

"So," she said, focusing on me once again. "The first thing you do is break things off with Melonie. She's a great girl, but you have to make it clear to her that you're just friends. And then, you have to make sure Karen is aware of how much she means to you."

"Flowers?" I said.

"That's a start," Mom said. "Tell you what I'm going to do. Tomorrow, I'm picking you up after school. You're skipping practice and we're coming home to make your sweetheart a nice, candlelit dinner. Don't worry, I'll run back to the office before she comes home. How does that sound?"

I grinned and have her a kiss. "Thanks, Mom."

She returned my kiss, but when I went for her breast she gently pushed me away. "Hey, tonight's a school night. And you should save something for Karen."

"Aw, Mom," I groaned. "You should realize by now that I don't have any trouble getting it up. Quite the opposite, really."

Mom raised an eyebrow and began to frown, but I saw her eyes dart to my crotch, where my hardening member was tenting my shorts. The frown quickly transformed into an impish grin. "My baby has become quite the little satyr, hasn't he?" she mumbled, almost to herself. She set the brief she had been reading on the nightstand and sat up, letting the covers bunch at her waist and revealing the silk nightie hugging her bountiful curves.

Grinning, I leaned forward to kiss her once more. This time when I grabbed her tit, Mom moaned and arched her back, pressing her hardening nipple into the palm of my hand. Mom broke away from me and slid out from under the covers, her tawny legs wrapping around my waist. I pulled the straps of her nightie down her shoulders, kissing her chin and throat and collarbone, and made my way down the slopes of her breasts as I pulled her nightie down to bunch at her waist. Mom's heavy breasts bounced into view, dark nipples hard and begging to be kissed. Naturally, I obliged them.

Mom moaned and ran her hands through my hair. "Oh yes, sweetie, suck my tits," she hissed. "You know how to make your mommy feel so good." I wrapped my lips around a nipple, nipping lightly and applying suction. Mom's tit pressed against my lips, and I licked around the nipple in concentric, widening circles, eventually switching to the other breast. Just as my lips brushed the underside of her breast, Mom pressed her palms against my chest and pushed me away. She shifted on the bed, rising over me so that I fell backward onto it. Her long blond hair fell in my face, tickling my nose, and she leaned down to kiss me again.

Her hands were busy at my waistband. Her fingers slid between it and my waist and pushed my shorts down, bending my hardened cock painfully. "Ouch," I said into her mouth, and Mom pulled back to regard me. I reached down to adjust my shorts and free my cock. Mom offered me an apologetic smile that quickly turned devilish.

"Shall I kiss it and make it all better?" she said. I groaned in response, wordlessly raising my hips so she could peel my shorts off my pelvis. My dick bounced against my belly, a copious amount of precum leaking from the tip. Chuckling throatily, Mom maneuvered herself between my legs. She gripped the base of my cock and angled it away from my belly. Lightly she kissed the purple, swollen head. It throbbed in response, squirting precum onto her plush lips. "My baby," Mom said proudly. "It's hard to believe this monster came out of my body, that I had a hand in creating this marvelous, mouth-watering cock." Her hand stroked me gently as she spoke, and her words made my cock throb in her hand. A veritable flood of cream was jetting from the crown of my cock, coating her hand and making it fly up and down it's length.

"Mooom," I pleaded, thrusting my hips against her hand.

"Don't use that tone with me, young man," Mom said mock-severely. She caressed the head of my cock with her palm, squeezing lightly. My juices squelched against her hand. "What did I teach you about politeness?"

I grinned, always enjoying the little touches of mothering that Mom put in our lovemaking. "Mom, please suck my cock," I said, as contritely as I could manage with a raging hard-on.

"That's better," Mom said approvingly. She ducked her head, sucking the crown into her lips to scrape her tongue along my pisshole, scooping precum into her mouth. Her fingers wrapped around my balls, cupping them lightly and teasing my sack. Slowly, Mom swallowed me, allowing her lips to slide down my length. Her cheeks hollowed as she applied suction, and it was my turn to run my hands through Mom's hair, encouraging her to continue.

Just watching my own mother with my cock in her mouth was nearly mind-blowing enough to make me bust my nut, even though she'd been doing it for months. It never ceased to amaze me or to give me an erotic charge, which was pretty much why I walked around with an almost constant erection. It didn't help that Mom and Karen had put a ban on masturbation, ensuring I saved all my cum for my women rather than the wads of tissue I had used before. Luckily, Mom and Karen were good sports about taking care of my needs whenever I got horny, so long as I returned the favor.

My cock throbbed against the roof of Mom's mouth, and I resisted the urge to thrust into her mouth. But just barely. "Mom, careful," I told her.

Mom released my cock from the sweet prison of her mouth with a loud slurp. Saliva and precum slid down the length of my cock and dripped from Mom's chin. Her tongue snaked out to lick her lips, and she smiled, eyes gleaming. "Oh?" she said. "I thought you had 'no trouble getting it up'? Are you saying that if I suck you just a little harder," and here she punctuated her statement by giving my throbbing member a burning kiss, "you're going to have trouble finishing what you started?"

"Uh. . .," I said brilliantly. "That's not really fair," I tried to say. Mom cupped my balls and gave them a gentle squeeze, causing me to jump. My dick bounced against her cheeks as I moved. "It's obvious I'm not thinking straight."

"Oh, you're thinking straight alright," Mom quipped, sweeping her hand along the lubricated length of my hardness. Then, as usual, she let me off the hook. Intellectually at least; she dropped her head once more and enveloped me in her mouth. Her lips stretched around my girth and her cheeks bulged as my cock pressed against the inside of her mouth. Mom sucked in a deep breath, her nostrils flaring, and then she swallowed me to the hilt. I felt her throat constrict around me as she took my entire length past her lips. Her mouth was like a vacuum, drawing me in, and I couldn't hold out for long.

In moments, my cock swelled, Mom's mouth grew tighter, and I felt my dick buck and throb as jet after jet of semen spurted from the tip, straight into Mom's gullet. As soon as I started spurting, Mom adjusted her grip on me to keep from choking. Her mouth slid up my cock so that only the head remained imprisoned between her ruby lips. The exposed length glistened with Mom's saliva and my juices. Mom's cheeks bulged with my cum, and her eyes gleamed with a mixture of lust and love. Still my cock spat its payload, some of it dribbling past Mom's lips to drip down my cock or her chin. Finally Mom released me and swallowed, and the last few spurts splattered against my belly as my cock slammed into it.

"Mmmm," Mom purred. She scraped cum off her chin with her nails and fed it into her mouth. "When was the last time you came?" she asked brightly.

My dick, threatening to wilt after my explosive orgasm, wavered between flacidity and hardness. "Yesterday," I admitted.

"Are you taking any vitamin supplements I'm not aware of?" she asked.

I shook my head. "Why?"

She gripped my cock at the base, levering it away from my flat stomach. At her touch, it instantly returned to its previous state, throbbing hungrily between her fingers. "You always come like a hose, baby," Mom told me. "And you are always ready for more. It occurred to me you might be taking something to help with that behind my back."

I shook my head again, grinning. I flexed my cock in her hand, thrilled at her touch. "One hundred percent natural, ma'am," I said. "I do think the constant sex is affecting me though. When it was just me jerking off in my room, I was never quite this. . . uh. . . copious."

"Mmm, new vocab word?" she grinned. "At least you appear to be keeping up with your studies." She released me and sat back on her haunches. Reaching down to the hem of her negligee, she swept it off her body in one smooth movement and tossed it aside to make a puddle on the floor. Mom's gorgeous, tanned and fit body was revealed to my burning gaze. "Now, how about taking care of your old mom?" she asked, stretching out on the bed.

"What would you like me to do?" I asked, shifting on the mattress beside her. My cock pressed against her tawny thigh, leaving trails of precum on her skin.

"After that, dear boy, I'll only be satisfied with a good, hard, fuck. Can you do that for mommy?"

"Uh-huh," I said with a grin. I slid one hand up her leg and she parted her thighs. I pressed my palm against her neatly trimmed mound, soaked with her juices, and slipped my thumb inside to tease her folds. Mom moaned and arched her back, pressing her pussy into my hand. My fingers sank into her. I pulled them free and licked each digit theatrically. Mom tugged my hand free from my lips and brought them to her own, sucking each finger into her hot mouth. With her free hand she gripped my waist and pulled me into her. I rolled with the movement, and my hardened cock slid across Mom's belly, trailing precum across its bronzed expanse.

Mom hissed and slapped a hand against my dick, pinning it to her stomach. "Enough screwing around, Billy, and get to the screwing."

I chuckled and kissed Mom's throat while bracing my hands against the bed. I adjusted my hips. My thickness trailed through Mom's steamy furrow, parting the lips of her pussy and eliciting a gasp and a shudder from her. Her hand wrapped around the base of my cock and aimed it at her hole. With one smooth thrust I rammed myself home. Home; one of the best words for Mom's steamy cunt. This was where I belonged, sheathed to the hilt inside her, my throbbing, bucking, driving cock swallowed by her sucking, gripping, burning pussy. She took my entire length effortlessly, the head of my cock bumping up against the roof of her cervix with appalling ease. I fit her perfectly, and she fit me, almost as if she had made me for that express purpose. We were two bodies trying desperately to become one.

Mom writhed beneath me and wrapped her legs around me, strong thighs tightening around my waist, her calves pressing against the hams of my buttocks. "Oh, yes, son, that's it. Fuck your mother. Fuck mommy, fuck me good!" Mom moaned in lust, her eyes rolling back in her head already, her heavy breasts bouncing against my chest, hardened nipples scraping against me. I did as my sultry, sexy mother asked. I fucked her good. My cock churned up a froth between her legs as I sawed in and out, pounding into her with all the strength and speed a teenager could muster. Mom reacted with equal enthusiasm, meeting me thrust for thrust. Our pelvic bones ground together in our mad mating frenzy. Mom's arms snaked around my shoulders, pulling me into a kiss that bruised our lips.

Our bodies slammed together, and each moan, gasp, and groan that came from Mom's mouth drove me to push myself farther and faster. Mom seemed to get hotter and wetter with each moment, and it felt as if she was sucking me deeper within her with each jab. "That's it sweetie," Mom said breathlessly. "Almost there, mommy is almost there." She broke off, breath hitching, and her entire body tightened its grip on mine. Her pussy gripped me like a velvet fist, clamping down with delicious intensity on my rampaging cock. Mom shuddered and shook beneath me. I didn't pause in my ministrations, however, knowing from previous experience that a sustained attack could trigger multiple orgasms in Mom. This time was no different; just as she seemed to catch her breath and begin to take up the rhythm once more, she went off again. Her nails dug deep furrows in my shoulders and her heels beat a tattoo against me ass. I grinned to myself and buried my face in the hollow of Mom's throat, still hammering away.

It was the third time Mom's frothing pussy squeezed my cock that my own orgasm finally hit. Like a lightning bolt from cock to brain and back again it hit me, and I felt my dick swell within Mom's juicy cunt and begin to spit jet after jet of creamy white cum into her heated depths.

Mom and I collapsed in a sweaty heap on her bed, me sprawled across her. With a grunt, I rolled over and stretched out beside her. Mom half turned and gave me a sleepy, satisfied grin.

"Such a good son to take care of your mother," she murmured, and kissed my shoulder.

"Thanks, Mom," I returned. I reached out and took her hand, then rolled once more and folded myself into her. Mom wrapped her arms around me and held me close. We drifted to sleep in one another's arms.
