~~~ Aunt Sarah ~~~

A week before the Thanksgiving break, Sadie's mom showed up at the house on Friday afternoon, unannounced.

The girls and I had just come home from our classes and were working on a few household tasks - knowing that we'd be starting dinner soon.

Grandma got Aunt Sarah a glass of wine. She sat at the dinner table as the four of us worked on preparing the evening meal. Most of her glass was gone by the time we got everything ready and brought it to the table. Grandma offered her a refill - but she turned it down.

Dinner conversation consisted of nervous chatter about schoolwork, jobs, and updates on family.

Finally, we cleared away the dishes and returned to the table.

I nervously ran my fingers over the sides of the water glass that sat in front of me.

Aunt Sarah turned to Grandma.

"I need to have a conversation with my daughter and Derek," she said.

"Unless it bothers you," Grandma replied. "Ellie and I would prefer to stay."

Aunt Sarah looked from my grandmother to my sister - who nodded - and back again.

"It's a ... rather delicate situation," she said.

"The kids and I have grown very close," Grandma told her. "I realize that Sadie is still your daughter but there's not much hidden around here."

"Then you are aware, are you, that the two of them are having sex?"

Grandma's facial expression didn't change.

"Yes," she said simply.

Her calm demeanor and lack of alarm caught Aunt Sarah off guard.

"I see," she said. "How long has this been going on?"

Grandma glanced around at the three of us. I don't know what Aunt Sarah interpreted from Grandma's look - but - what I got was: "We're only admitting to what she already knows. Keep the story straight in your head and don't mess this up."

"Shortly after Sadie joined us," I believe, Grandma said.

"Yeah, like the first night," I thought, thinking back to our sexy-time in the tent.

"This doesn't bother you?" she asked.

"They're exploring," Grandma replied. "They're old enough to make up their own minds and - if forced to hide it - might make things worse. She's on the pill."

"Ah ... yes," Sadie's mom stammered.

Her momentary bit of righteous indignation had been snatched away.

My first cousin and I were having sex. Everybody knew about it. Now what?

"My ... uh ... sister and my husband ... would not be so ... understanding ...," Aunt Sarah said.

Her words were somehow strong - and yet weak - all at the same time. Grandma cut to the chase.

"... and the price - for you to keep their secret - is that you wish to share your daughter's lover?"

"John ... John does not like to have sex anymore," Sarah told her.

"You can keep your excuses to yourself," Grandma said to her. "You came here - not to judge your daughter - but to taste the forbidden fruit for yourself. Do not sully the girl's image of her father in order to justify your lust."

"You're ... you're right," Aunt Sarah admitted, her head lowered.

"Derek, your aunt knows your secret. The price - for you to continue your relationship with her daughter - is for you to take the girl's mother to your bed."

Aunt Sarah's eyes shot up to mine. I looked at Sadie.

"Sadie?" I asked.

"What?" she said. "It's not like you can tell her 'no'. She's right that daddy wouldn't take it well."

Sadie turned and faced her mother - but she was still speaking directly to me.

"Make her scream your name as she cums on your cock and there will be no secrets for her to tell anymore."

If I thought Sadie's words would cause her mother to reconsider, I was wrong. Aunt Sarah turned back to look at me. The doubts and fears were gone - now that she could see her prize clearly.

"A word, Derek," Grandma said.

I got up and followed my grandmother to her room. She closed the door.

"Be kind to her. I know you and Sadie are a little unhappy with the woman right now, but I don't want you to retaliate in any way. I don't want you to belittle her. She will be your lover tonight. Show her the same love and affection that you show the rest of us. She's nervous, she's a little scared, and she's horny. Make love to her, my boy."

"Yes, Grandma," I said.

She hugged me and gave me a peck on the lips.

"Make her scream your name as she cums on your cock," she ordered, smiling at me.

"I will," I promised, smiling back.

We returned to the dining room and Grandma suggested that we play a few card games - which told the rest of us that we were not introducing Aunt Sarah to the hot tub.

We dug out a deck of cards and played a few games. Spoons was actually way more fun with five of us - but it was obvious that Aunt Sarah really had nothing on her mind except getting my cock inside of her.

I had to admit that I was actually getting a little worked up, thinking about fucking my mom's sister. I was already fucking my dad's mother and this would kind of even things out, in a weird way.

Thinking back to that night in Sadie's bed - and the noise that I thought I'd heard in the hallway - I decided that had to have been her mother.

We played another round or two of Spoons and then Grandma told Aunt Sarah to grab her bag and follow me to my room.

~~~

I wasn't sure how she wanted to proceed. She'd been fidgeting the whole time we'd played cards - wanting to escape from the others - so I stripped off my clothes and stood in front of her.

She stood and looked me up and down, zeroing in on my cock. She swallowed nervously. I grinned. Seeing her swallow as she looked at my stiff prick had me thinking about how I wanted her to swallow my load.

I stepped up into her personal space.

"What are you doing?" she asked nervously.

"I thought maybe we could kiss while I undress you," I said. "Would that be alright?"

She looked from my dick to my lips and said, "Yeah, alright."

I hugged my arms around her body and pursed my lips. She started with a peck. That turned into a real kiss. Soon, her mouth was all over mine. Not long after that, she included a little tongue. I shifted my hands to her ass and kissed her harder. Her arms went around my neck, and she was soon lost in what we were doing - until she ran out of air. She pulled back and panted, trying to catch her breath. I began undoing the buttons on her blouse.

"Derek ...," she said.

I stopped and looked up at her.

"This ... this is wrong ...," she said.

It didn't make much sense for her to have a crisis of conscience - not after she'd driven three and a half hours to get here - knowing she was going to confront her daughter and me about having sex in their house. She wanted fucked and Grandma had said to make her squeal.

"Do you want me to stop?" I asked.

She bit her bottom lip and said, "No."

She stole kisses, periodically, as I removed more and more of her clothing. Soon she was down to her brassiere and her panties. It was a fairly plain and unflattering lingerie set. I briefly thought that I knew what to get her for Christmas - to spice up her underwear drawer - and then had to smother a chuckle that would have been hard to explain.

I kissed across the exposed skin above her bra, and she sucked in a breath. Her hands went to my head - and her fingers into my hair. I grabbed the underwire, tugged out and up, and her fat DD titties flopped into view. I shoved her bra up and cupped her impressive rack in my hands and began making love to her tits with my face and mouth.

One hand stayed in my hair but the other went questing lower. She caressed my balls and then began slowly stroking my prick.

"God, that feels amazing," she moaned. "It's been so long since someone sucked on my tits."

I brought the nipple to my lips, tongued it, nipped it with my teeth and then sucked - sucking harder and harder until she hissed - then I switched to the other one and did the same.

"Derek," she moaned. "I need you."

I slid a hand to the crotch of her panties, pushed them to the side, and slid a finger inside of her. She was beyond wet. I shoved the finger in as deeply as it would go - and then slid it in and out.

"Fuck! Oh, fuck!" she moaned.

I pulled my finger out, brought it up to her lips, and held it for her to suck. She did. She stroked my cock as she sucked her own slickness from my finger.

I leaned in and kissed her hard, tasting my aunt's naughty-sauce on her own tongue. She was losing control. Her kisses were hungry, and her hand (on my stiff rod) was getting more insistent.

"I want to taste you," I whispered.

I reached behind her - our lips still locked together - and unclasped her bra. It tumbled from her shoulders and wrapped around her hand as it worked up and down my cock. She chuckled and finally let me go - allowing the garment to drop to the floor.

I dropped to my knees, took hold of the waistband of her panties, and looked up at her.

"Please ...," she begged

I pulled them down - slowly - so slowly that she whimpered with anxious need.

I licked up the front of her labia - to her clit - and the trimmed landing-strip above it. I didn't dig inside - just lapped at the surface. She moaned and writhed.

"Oh, Derek ...," she moaned.

She pushed my head away, threw back my covers, and climbed onto my bed.

"Feed that fat cock to me while you lick my cunt," she demanded.

She lay on her back and grabbed my hand - insistently pulling me towards her.

I climbed on top of her - standing on all fours - and she immediately took hold of my cock and brought it to her lips. She sucked the head of it, and I just about lost my mind. I'd gotten myself worked up too much. I was going to need to hurry to make her cum before I exploded. It looked like this night was going to be a play with two acts - oral and then vaginal.

I pulled her legs up, threw my arms behind them (raising her butt off of the bed and pointing her cunt at my face), and held her there - giving me full access to her vulva and her dripping twat. I sucked, licked, and nibbled every bit of her girl-flesh as she screamed and writhed.

She was so caught off-guard by my oral assault on her sex that she ignored mine completely. It lay, forgotten, against the side of her face. That was perfectly fine with me. I knew I'd explode before she even got me into her throat, and I wanted her to climax at least once before that happened.

I licked, sucked, and nibbled her bits until she was frothing at the mouth.

She'd cum twice - and was hoarse from screaming - by the time her need abated enough for her to notice my prick and decide she was ready to take my load.

Sadie's mother was a talented cocksucker and - sure enough - by the time she had the nose of my cock buried in her throat - my balls were willingly giving up their load.

I turned myself around and lay beside my mother's sister, looking into her face. She kissed and licked her slickness from my mouth and lips and then pulled me on top of her to make out. She reached down and slid my prick towards her entrance.

"I can't yet," I told her.

"Soon enough," she promised.

We made out as she used her cunt, fingers, and labia to torture my poor cock back into submission. As soon as it was hard, she shoved it inside.

She worked her cunt up and down my prick - thrusting from below - her body hungry for everything that I could give it.

I thought briefly about the fact that I was fucking the birth canal where my sexy little cousin, Sadie, had been brought into the world, 18 years ago. My cock stiffened at that thought and my mother's sister moaned as she felt it, deep in her vagina.

Aunt Sarah rolled me onto my back and began riding my cock - pistoning it in and out of her cunt. She pulled out until we were no longer joined - and then she would thrust forward again - shoving my cock back inside of her once more - as if it were the very first time.

I got that uneasy feeling again, as my mother's face superimposed itself over her sister's. They looked a lot alike and - for a moment - it seemed like it was Mom fucking my cock in and out of her cunt.

Aunt Sarah moaned and the vision passed. My extremely nice-looking aunt - who was responsible for how cute my favorite cousin was - was using her gifted twat to coax my balls back to fullness once more.

"If you're through letting me do all of the work, nephew," she said, grinning, "I'd like to be fucked now."

I rolled her onto her back, wrapped my fingers over the front of her breasts, squeezing her nipples, areolas, and tender tit-flesh in my fists. I held on and began slamming my cock inside of her.

"Is this what you want, Aunt Sarah?" I asked.

"Yes ...," she hissed.

"You stood in the hall and watch me fuck your daughter, didn't you?"

"Yes ..."

"Did you touch yourself?"

"Yes."

"Did you imagine it was your pussy that I was fucking?" I asked her.

"Yes."

"Did you cum?"

She moaned and shook her head - trying not to answer - but I glared at her and stopped fucking her.

"Please ...," she begged.

"Answer me," I told her.

"Fuck me and I will," she promised.

I began sliding in and out of her again - more slowly - waiting to hear her story.

"I went back to bed, worried that you'd seen me. I lay there, next to my sleeping husband, unable to sleep, needing something buried in my pussy - like a bitch in heat. I slid one of my dildos into my ass and then I finger-fucked my twat (picturing your dick slamming into Sadie) until my pussy exploded - soaking the bedsheets. I wiped off the dildo and put it away and then pulled the blanket over my sweaty body. I slept in my filth-covered bed until morning - lying there until Uncle John finally left for work and I could change the linens."

My cock had twitched several times as she told her tale.

"You're a naughty, naughty girl," I told her.

"Do you like naughty girls, nephew?" she asked.

"I do," I told her. "My balls get so full of jism that they ache - and then I have to find some place to empty them."

"You can empty your balls in me," my aunt offered.

"Is that what you want, Aunt Sarah?" I asked.

"Yes."

"Tell me what you want," I said.

"I want my sister's handsome son to fuck my pussy until I cum on his fat cock," she said, "and then I want to feel him pumping his hot forbidden seed inside of my womb."

I reached down, hooked my arms under her knees, and pushed forward - curling her up so that I could fuck her deep and hard.

"Oh, fuck ...," she moaned as she sensed what was coming.

I pulled all of the way out of her - like she had done when she had been on top - and then slammed back in.

"Fuck ... yes ...," she moaned.

I fucked her then. I fucked her like she had begged for it. I fucked her like I had fucked her daughter. I imagined my next trip to her house. I imagined fucking mother and daughter together on Sadie's bed - while Uncle John soundly slept down the hall.

I roared and fucked harder, deeper, and faster.

Oh, fuck, Derek!" Aunt Sarah gasped. "Fuck me. Fuck my dirty cunt. My cunt belongs to you now. Claim this pussy. Fill it with your fat cock until nothing else will do. Make my twat beg for you. Make me scream as I cum on your cock and then fill my womb with your sperm. I'm not on the pill and every time we do this, there's a chance you could get me pregnant."

I was nearly at my limit anyway - but the images of Sadie's mother - pregnant with my child - filled my mind - and I slammed my prick into my aunt's cunt again and again, bouncing the head of my cock off of her cervical wall.

"Fuck me, Derek! Fuck me, Derek! Fuck me, Derek! Oh ... fuck ... I'm so ... ooooh ...," she cried out.

Her vaginal muscles gripped me like a vice - and I shoved in deep - and came at the same time as her - roaring as my jism splattered inside of her.

I had no clue whether or not her chatter about me knocking her up was just words - but I wanted it - I wanted to make her pregnant. I wanted to be the father of Sadie's little brother or sister.

~~~

Aunt Sarah helped the others prepare our breakfast and told me to go sit at the table. I watched the four women - all of whom I had fucked - as they worked together, chattered, carried on, and giggled. I didn't think I had ever seen Sadie's mom acting so relaxed around her. They looked and acted more like sisters.

At the table, Sadie switched to Ellie's side so that her mother could sit beside me. We didn't talk about relationships or sex. We talked about the upcoming holidays and discussed the possible schedule for our visits. Aunt Sarah told Grandma that she was more than welcome to come along for whatever festivities took place.

There was never a suggestion about extra-curricular activities. She had, apparently, gotten her fill of those the night before. It was as if we were all just a normal family, discussing normal things. It was the most laid-back that I thought I had ever seen her. It was nice to eat and visit with no tension around the table.

After the meal, she gave everyone hugs and cheek kisses. When it was my turn, the kiss was not on the cheek - and it was not chaste. That was the only real sign - from the morning's activities - that gave anyone any hints that this woman had woken up naked next to me - with a big grin on her face.

We'd woken early enough that I was able to give her one more thing to grin about before she'd gotten dressed to leave my room.

We watched Aunt Sarah pull out of the drive and, without being told, followed Grandma back to the table.

"That was close!" Ellie laughed. "She thinks Derek is just sleeping with Sadie."

"She'll be back," Grandma prophesied. "You know how irresistible your brother's dick is. She'll want more."

"She already said, last night, that her pussy would never be happy with another penis," I reported.

"Like daughter, like mother," Sadie gushed, curling herself around my arm and squeezing.

"Your Aunt Sarah," Grandma told Ellie, "will find out all of our secrets soon enough - but Sadie was right - she's now compromised her ability to tell anyone else without implicating herself."

"Am I that loud when Derek fucks me?" Sadie asked.

Ellie nodded and snickered.

Grandma grinned and said, "Like daughter, like mother."

Sadie blushed as the rest of us laughed. I leaned over and gave her a sweet kiss.

"It's hard not to cum in you when you beg for it that loudly, Sadie," I told her. "You make my balls ache."

"I love it when you cum in me," she purred.

"So does your mother," Ellie laughed.

"Yeah, apparently," Sadie said, laughing as well.

Grandma waited for us to settle down.

"I don't think she'll visit every week - but I think we can at least expect her to drop by once a month. The coming holidays, of course, will throw that off."

Grandma shot me a look.

"Make sure your uncle is definitely asleep before you stack daughter on top of mother and fuck them both on Sadie's bed," she said.

Sadie sputtered, "What .. who ..?"

Ellie looked from Grandma to me and said, "Yeah, that's definitely already gone through his mind ..."

Sadie's fingernails dug into my arm, and I turned to look at her. I expected to see anger but the fire that was burning there was fueled by lust instead. I could almost hear my pants straining to contain my growing cock.

The rest of the day was spent doing homework, catching up on chores, and getting the rest of Grandmas flower beds prepped for the cold weather.

Mid-terms had come and gone, and the girls were doing well. I'd helped each of them with a little math, but they'd finally glommed onto it and hadn't really struggled since. I was doing well. I thought about trying to add more hours - to get done a semester earlier - but the pace was working for me.
