Kelly was already home and was wrapping herself around me as soon as I let myself into the flat.
"How was your first day?"
I told her all about it, even about the samples bin.
"I have seen some of these things, the underwear looks great" she told me "I even have a small vibrator."
"You never told me about that?" I was a little shocked.
"It's not something you normally tell your brother and " she squeezed me" you never asked me, but you are now more than just a brother."
We kissed for what seemed to be an eternity, Kelly constantly squeezing my arse, so I returned the favour.
"If you are a good boy I may show you it sometime, but you had better phone mum" she suggested as we came up for air "she will want to know all about your first day and It will give me a chance to get dinner ready."
As I dialled the number I watched Kelly walk into the little kitchen. Mum picked up the phone after a couple of rings and listened as I told her about the day.
"Have you enjoyed it so far." She seemed a little distracted.
"Yes I have, the job seems easy enough both James and Frank seemed pleased with how I performed and they do have an easy system for stock."
"Will you be coming home any night this week?" She almost whispered.
"Are you okay mum?"
"I'm fine" she paused "It would be nice if you could stay here one night this week and perhaps we could talk again."
"Talk again?"
"Like the other night?"
Was my mother asking me to have sex with her again?
"Are you sure?"
There was a long silence over the phone.
"I'm sure" she drew in a deep breath "I haven't felt like that in so long. But only if you want."
"Okay" I thought for a few seconds "It's early closing on Wednesdays, so I could get the bus over."
"That would be lovely, Tasha is missing you" she whispered again "I'm looking forward to it and I know Tasha would be happy to see you." She finished in her normal voice.
"Should I get some protection?" I asked quietly.
"We will be okay, don't worry."
I couldn't believe the fact that we were planning a sex session over the phone.
"What about Tasha?" I asked quietly.
"She always sleeps like a log. Has she found out about you and Kelly?"
"Yes." I replied.
"Oh, well we will have to be careful."
I agreed with her. We chatted for a little longer before Natasha asked to speak to me.
"Hello pest!" I said.
We chatted mostly about my first day and it wasn't long before we ended the call. Over dinner I told Kelly It would be a test to see if I could commute across the city.
"What was all the whispering about?" She asked.
My mind went into overdrive, more lies!
"She wanted to know how you had reacted to her finding out about us and that we should be careful around Natasha." The lies were stacking up.
"Natasha knows about us." Her voice was hushed.
"How?" I acted surprised.
"Remember when I was sat on your lap and she barged in on us?" I nodded "well she told me that she could see that you were hard and inside me."
"What did you tell her!" I made it sound like I was a little angry but knowing the truth made it difficult to not smile.
"Everything" she looked down at her hands "I don't know why I did, but I told her everything."
I continued to stare at her.
"She promised not to say anything" Kelly put her knife and fork down and grabbed my hand "honestly, I think she will keep it secret, I have told her things in the past that she has kept to herself."
"I hope so." I replied.
We continued eating Kelly deep in thought.
"When you go home on Wednesday, talk to her and make sure she understands that she has to keep it secret."
"I will."
"Are you angry that I told her?" She asked.
"She was bound to find out" I leaned over and kissed her"I'm not angry."
"I promise to make it up to you." she began eating again.
"She did ask me" I confessed "and I did tell her to ask you."
"You little bugger!" She punched my arm and laughed "I hope you aren't tired because now you owe me and my period should start Tuesday or Wednesday."
"Should?"
"Don't panic!" She smiled "that's the good thing with the pill, your periods are predicable, it's normal!"
We finished eating and I did the washing up. Kelly was quiet the whole time I washed the dishes, when I finished and left the small kitchen I found out why.
"Desert?" She was sitting on the edge of the table completely naked.
Her right hand was slowly moving between her legs, I could hear a wet sound from her pussy as she played with herself, I quickly stripped off and was soon standing between her outstretched legs. Kelly shuffled back on the table so I rubbed my hardening cock on her clit. She groaned with pleasure so I did it again and again receiving a low groan each time.
"Oh god that's so good!" She sounded surprised.
I then slapped my cock against the her clit making her gasp and slowly slid it down between her lips, pushing slightly forward. As soon as I felt a bit of give, I thrust forward forcing the head and a short length of my rock hard cock into her hot, wet pussy. She flinched then groaned, she felt very tight despite being wet. She must have been playing with herself for sometime because she had her first orgasm seconds after I pushed into her. Throwing her head back as her fingers flew back and forth across her clit until suddenly she started to shake and whimper as she came. I pulled back before thrusting with all my might and watched my cock almost completely disappear into her.
Kelly yelped.
I held my cock deep inside her for a second or two before pulling almost all the way out of my sister, then slamming back into her.
Kelly lay back on the table, lifted her legs up and I felt her cool feet press into my ass cheeks, so I slid my hands under her knees and wrapped my arms around her thighs. I pulled her forwards so her ass was overhanging the edge of the table. Holding her steady I started to fuck her, slowly at first whilst her tight pussy got wetter.
"Yes, don't stop." She gasped.
She began writhing as I pushed into her, again and again, each time my balls were slapping her arse, I began slamming harder into Kelly, deep in to her, hard and fast.
"Oh shit Alan" she gasped "I'm coming again!"
I could feel her tightening around me, it felt as if she was pushing me out. I pulled her hips towards me, digging my fingers in to her flesh and with one last deep push I came, with each throb of my cock I pushed my hips forward, pulling away a little before the next spurt of cum made me push forward even harder.
Kelly was still twitching as I finally stopped. Letting my weight press against her I remained deep inside her.
"Christ Alan!" Kelly finally spoke "Were you trying to fuck my brains out?" She smiled.
I was gasping for breath, my cock still buried deep in Kelly.
"I kept thinking of getting you pregnant, it really turned me on!" I finally gasped.
"Really?" Kelly sounded shocked.
"I know it's stupid!" My cock was still hard "Something in my head told me I had to try!"
Kelly chuckled, lifted herself up on one elbow, reached out with her free hand and pinched my right nipple.
"Keep thinking like that" she moved her hand to my left nipple "that was fantastic!"
"Keep doing that and I may do it again!" I replied.
She lay back on the table. At some point she had relaxed her legs. Looking down at Kelly I felt a pang of guilt. She had been my first but since then I had fucked, no other word for it, two other's. Debbie she knew about but our mother was still a secret, one that I didn't want her to know about. Kelly sighed bringing me out of my thoughts. My plain tomboy sister was looking deep into me, almost searching out my soul.
"I need to get up Al." She whispered.
