It's been years since I last saw my family, and hence I was eagerly looking forward to Christmas. I had pre-arranged to have the whole month off, and with large bonus work gave me I had plenty of money to spare for the trip.
The trip there took three days, The last thing I was expecting was for my sister and her children to have also been visiting. After not seeing her in years I was over-joyed at the sight grasping her in a big bear hug squeezing as tight as I could, suddenly i was greeted with a sharp pain in the side.
"Ow, you bitch that really fucking hurts" I exclaim as I come to the realisation my demonic little brat of a sister was digging her nails into my skin.
"I know, but you love me though. I love you..."
"Do I know? I love me too." I release her from grasp, picking up her kids one by one saying my hellos.
Our first week was just spent shopping I was more then happy to spoil everyone with gifts and lunch all week. Upon later reflection I would note her outfits got bolder and more revealing as the days went. The next couple days were spent bonding awaiting Christmas day. The morning of I'm awoken to her jumping on me, pinching my sides yet again. No matter how much I begged there was no stopping the relentless attack of her nails, in fact the pain had started to turn me on. I had to make her stop...
With a bit of a struggle I managed to flip her over, pinning her down taking the chance to catch my breath. She slips her legs around my waist almost like a snake, with a strength to match that of an anaconda. We held this position for little over five minutes, feeling each-others breath. I was slowly losing control of myself, my member growing between us. The heat coming from my sister was unmistakable. Was she getting horny as well?
"BRITT WOULD YOU LEAVE YOUR BROTHER ALONE SO HE CAN GET DRESS AND WE OPEN OUR PRESENTS" Phew I was saved.
I released my sister, after a few more pinches she finally let me go. Rolling away to the safety of my covers I wait for her to leave.
"don't take too long alright?" she states before finally leaving.
The rest of the day pass without much of a hitch, after lunch I took a walk to piece together the events of that morning.
"It just doesn't make sense to me." As I get home everyone is outside having a few drinks, we make some prank calls before calling it a night. At least that was the plan, after a quick shower I go to lay down only for my down to burst open.
"Wake up you boring bitch."
"I am awake..." I state in annoyance. Barging in, Brittany closes the door behind her stealing the spare key to my room.
"What did you just take?"
"Nothing..." She takes a step forward sitting on the foot of my bed, that's when I noticed the glisten of the key. I lunge forward making a wild grasp for the key, which she hides behind her back. To my shock the button of my boxers unclasps my cock slips through the opening in a heartbeat. The chance does go unnoticed she flips around sitting on my lap pulling her booty shorts higher. The combined factors of her skin and the fact I had not received a sexual act in a year or so left me rock solid against her crotch.
Our position had us staring into each other's eyes in the mirror, as she began to twerk on me. Trying to gain some control I grip her throat and pull her back against myself whilst fishing for the key with my freehand. Thats when she ground back against me, my cock finds an opening in her shorts leg holes. I can feel it, the wetness of her panties against the tip of my cock, I couldn't stop myself, I thrusted against her wetness a couple of times. SHIT. I want to...
