A few years has past and Nancy and I are closer than we ever has been. Of course we have had our ups and downs like any relationship but we are strong enough to get through it all. We are careful enough to not get caught and even went as far as seeing other people but that really wasn't fair to anyone. It was the final few weeks of college, before finals. We had a plan to move away and start a life where we would not have to hide as much and we were eager to start a new chapter in our lives.
Nancy had her eyes squeezed shut, mouth open, and her breath ragged. She was on all fours concentrating on her impending orgasm. I had a fist full of her red hair, slamming my dick into her pussy and it gripped and massaged me.
"Pull harder and fuck me..." Nancy gasped
I pulled until I thought I was going to hurt her neck and her head was as far back as it could go. I began to fuck her faster and harder. Smacking noises began to fill my tiny dorm room. I could feel the sensation in my cock of an imminent explosion and I began rubbing her clit with my free hand.
"I can feel you getting harder... just let it go... I can't cum until I feel you pulsing inside of me!"
I felt all of my seed race up my cock and out of the warm, sensitive tip and into my sister's womb. It immediately felt slightly warmer and a lot slicker as I pumped seven or eight spurts into her.
"uuuuuhhhhhhhhh!" she cried as her orgasm hit her tingling pussy and traveled through her body.
Her pussy clamped around my dick like a vise and trapped me deep inside of her. I released her hair and she collapsed onto the bed and I rolled off as soon as I could as I felt the beginnings of a cramp tighten my left hamstring from my efforts. We lay breathing heavily for a moment then she put her head and my chest and cuddled up to me. My cock was still rock hard a pulsing in time with my heartbeat. It glistened with our combined juices.
"You don't get soft right away, like other guys" she giggled.
"That's because it wasn't just in any other girl. It was in my sister." I grinned.
"That's sweet. I want to fall asleep but I had a study group I'm going to be late for" She sighed.
She jumped up and threw her clothes on, gave me a kiss and ran out the door. Soon after I was out like a light. The growling in my stomach woke me up an hour later and I needed to take a shower. I looked down at my sister's dried cum on my cock and I thought to myself that it looked like I just fucked a glazed donut. Soon I was out of the shower eating some ramen and studying for finals. I couldn't wait to get out and get a high paying job so I would never have to eat ramen ever again!
My phone beeped and I could see it was a text from Nancy. "Some of us are getting a drink. Want to meet us?"
As much as I wanted a beer I really needed to study. "I think I'm in for the night. Don't stay out too late!"
"Suit yourself! BTW I can feel your cum leaking out of me and into my panties! It feels so dirty! I love it! ;)"
"Lol! I'm glad you like it!"
"Too bad we have to go back to condoms for a while :("
"I know... not for too long I hope!"
My sister was going to stop using her current birth control until she could find another type due to the headaches she was experiencing. We used the spray and pray method a few times in high school but we've been careful since then.
"Have fun but don't stay out too late!"
"I won't! Love you! :)"
"I love you too"
Soon I was asleep. Over the next week I didn't see Nancy much but we would text a lot. Mostly stuff to do with finals and our parents coming for graduation but I would wake up to a sexy pic from time to time. It was a good thing I never let anyone see my phone! Soon finals were over and it was three days before graduation. Nancy and planned on moving out west to LA and starting a life together out there. I couldn't wait! We had a lot of family and friends that wanted us to stay nearby but were tired of sneaking around.
I woke to the sensation of suction on my dick and hair tickling my lower stomach. I raised my head and grabbed two handfuls of red hair so I could see Nancy's face.
"Ooohhh, Nans..." I moaned
"Mmmmmm" she moaned. She pulled her mouth off of my cock and let some saliva drip onto it as she cork screwed her hands up and down.
"I missed you, brother" she smiled as she licked the underside of the head of my prick. She stared directly into my eyes as I propped myself up on my pillows and elbows. She knows how much of a turn on for me it is when she does that. She buried my cock in mouth until her nose was touching my stomach.
Bang! Just then someone pounded on the door. I nearly jumped out of my skin! Nancy was clearly startled as well.
"Robert?! Are you in there?!" My mother called out.
Nancy was jumped out of my bed and onto the chair at my computer. "Yeah! Just a second, Ma!" I yelled.
