Dinner was filled with me discussing college life with mom and Avery telling them all about football practices and the season starting soon.
"How are your classes going?" she said with a raised eyebrow.
I let out a nervous laugh and rubbed my neck, "They could be worse, but I'm not failing any of them." I said.
She raised both of her eyebrows, "Alright Mason if you know what you're doing then I trust you." She told me.
Me and mom were really the only ones talking with the occasional "yes" and nods from Avery but she mostly stared at me with that knowing sparkle in her eyes as if she knew what nasty deed I did in my bedroom.
After dinner mom retired to bed because she said she had to get up early for work in the morning while me and Avery went into the living room to watch TV and possibly catch up. Both of us were sitting on the couch me at one end and her on the other. We were watching some reality show about basketball player's wives which seemed like a funny and odd topic for a show but was satisfying. I felt a tingling sensation on my face and looked out of the corner of my eye to see Avery intently looking at me. I grabbed a pillow while still staring at the TV and threw it at her hitting her in the face like old times when we were little and she would stare. She grabbed the pillow and stared at it before focusing on me and coming to my side of the couch moving on her knees and tried hitting me back in the face, but I held my arm out stiff arming her while she tried to get around to me with a hint of a smile to her lips. She swung randomly hitting me with a little more force than she probably anticipated. Her face reverted back to that same neutral expression and was staring back at me with a look of intensity.
I stared back with a smirk on my face and grabbed another pillow at my side when the best idea of my life came to me. "Why have I never thought of this before?" I was thinking to myself.
I let go of the pillow and pull my sister in a bear hug digging my fingers into her sides tickling her. She lets out a burst of air as she tried to hold the laughter in, but lets out a squeak as she goes into a fit of giggles and laughter. It was the most ear pleasing thing I've ever heard. Throughout the time I've known her the closest she's got to laughing was a short chuckle at my corny jokes I used to tell. I wanted to hear more of her musical squeals and giggles.
I moved up along her sides to underneath her arms, she started squealing louder at the new tickling sensation. She was squirming a lot and then flipped over onto her stomach trying to crawl away, I brought my large frame over her and straddled her butt. I dug my fingers back to her side wiggling them randomly around and reached back with my other arm and tickled her feet, she let out gasp and her giggling fit doubled as she tried to buck me off.
A shiver of pleasure tingled its way through my body. I looked down to see that I was hard as rock, and my dick was sticking out prominently through the loose material of my shorts. It was nestled right between her glorious cheeks, they were round and perfect not to firm and not to jiggly. The soft friction of my shorts and the soft round cheeks of Avery were bringing me close to the edge, the tip of my shorts was darkening as pre-cum soaked through the material. I didn't know what to do I was panicking, I couldn't get up I was afraid she would see my erection and label me as a pervert and she really wouldn't talk to me, and I couldn't keep tickling her because the noise would probably wake mom and she would see me straddling her butt with an erection and disown me or something and then Avery would hate me for embarrassing her. I looked up and noticed the downstairs bathroom in mom's hallway. I decided I had to make a run for it if I were to make a safe getaway.
"I have to use the restroom," I jumped up and made a mad dash for the bathroom. Opening the door and closing it, I quickly pulled down my shorts my cock sprang free looking red and angry, I grabbed hold of it and stroked up and then down and I came everywhere all over the toilet the side of the wall and sink. It felt like an electric current I was cumming out, I was breathing heavily and was dizzy from yet another euphoric jack off session.
I took a moment to collect myself together wiped up the mess I made and flushed it down the toilet. I stepped out of the bathroom and the lights were off and Avery was sitting in front of the TV being bathed by the colors. I walked around the couch and sat back down as if I just didn't get a hard from my sister butt and go jack off in the bathroom. Suddenly the couch dips down and she crawls in my lap laying her head on my chest underneath my chin.
"I'm cold," was her only explanation besides the fact that it was indeed a little chilly, the act of Avery huddled against me was more innocent when we were younger, but now seemed a lot more intimate due to our older age. I could see her vast white cleavage looking very soft below me in her tank-top. I could tell she wasn't wearing a bra as they had a slight sag to them and I felt a familiar stirring in my pants even though I just came buckets in the bathroom. The scent of Apples and rain filled my senses. My pole was hard as rock now and I was pretty sure Avery could feel it prodding her, there was no way she couldn't.
"I'm such a sick fuck." I mentally bashed myself. "Avery I-I'm getting tired, I think I'm going to go to bed." I said.
She pulled back and pierced my gaze with hers, "I know you're hard," she said softly. She squirmed in my lap rubbing her ass against my crotch and I let out a groan at the sensation. Our faces are inches apart and her breath was a little labored and hot on my face.
"Is it because of me?" she asked
Her constant squirming and eye contact were driving me over. "Avery I need to get up," I rushed out, she turned fully around and straddled my lap moving her hips back and forth in even rhythm, she threw her arms around my neck and I instinctively grabbed her waist.
Her eyes had me in a trance I couldn't look away even if I wanted to. My brain was saying, "STOP THIS IS OVER THE LINE, FUCKING WRONG!" But I was thinking with my dick and it overpowered all other rationalities. The scent of something sweet and musky was tantalizing my nose.
"What's that smell?" I thought, "is that her, is she getting off from this?" I questioned myself. Her eyes were a dark green and half-lidded, she was breathing hard and so was I. It was heaven what she was doing to me, she started to pick up the pace and the air was thick with her arousal the room felt hot and empty as if it was just me and Avery floating in bliss. I felt my balls tighten and my dick throbbed one last time before I let out a grunt and moan and shot another load in my shorts, I felt the hot seed spread all over my thighs and balls as I kept pumping into them. Avery must've also gotten herself off because she lost the rhythm of her rubbing and her hips were erratically jerking back and forth as she let out a whimper and her body stiffened and eyes closed tightly as she let out a squeak, I felt extra heat meld with my on as she flooded her own shorts. She released a breath and fell forward till our foreheads pressed against each other, her body shuddered one last time and she lazily opened her eyes which were still dark with lust as our eyes connected. Our labored breaths were in rhythm with each other still fast from our erratic sexual high.
