The Twins

A/N: This is just something that’s been kicking around in the back of my head as an idea for months, obviously this is pure fiction, and names were chosen at random.
Contains: Incest

I was walking through the hallway of my home when I felt my dick twitch and sense of arousal in my stomach, and that was all the warning I got.

*Thump*

I looked down to see a bare foot, my twin sister Lily’s bare foot, buried in my junk. A groan of pain slipped past my lips at the same time a moan of pleasure slipped past my sister’s. I crumpled to the floor, holding my aching nuts and hardening cock. I guess I should explain how this all started.

My twin and I have a psychic link of some kind, where we can feel what the other one feels, be it physical or emotional, there is a distance limit to, as we found out a few summers ago when I went to visit our grandparents out in the country while my sister stayed at home. Now you might be thinking ‘wait, if your sister feels what you feel, why is she kicking you in the balls?’ and the answer to that is, my sister is a masochist, and getting ‘her’ balls bashed gets her engine going like nothing else. The only problem is that ‘her’ balls are my balls. She discovered she was a masochist well before she discovered the joys of ball pain, and I knew that through our link, just like I knew the moment one of our friends cup checking me was going to change how I was going to walk around for probably the rest of my life.

It was winter break of our senior year in high school, and my sister and I were hanging out with a group of our friends. Charlie, who was one the swim team with me back handed me right in junk while we were walking around the mall, and let me tell you, the force and the unexpectedness of it made me fall to my knees. While I was holding myself in pain, I felt my dick start to get hard and an arousal that I could tell was coming from my sister who had fallen next to me made me realize that things would never be the same, which is how I found myself on the ground again.

It was half way through our first term in college, and Lily, and I were living in an apartment five hours from our home town. I was in basket ball shorts that offered no protection to the kick that had just toppled me, and I looked over my shoulder to see my sister in panties and a loose tank top, not that it really mattered as after I fell to my knees my sister had dropped her panties and started to touch herself. With another groan I got up and dropped my shorts, knowing by now that even if I tried to get Lily to stop, once she had started, nothing short of an emergency would get her to stop. My scrotum was red from the fact that this was the second time today that we were doing this, and the fourth time this week despite it only being Wednesday. As Lily played with herself, my dick grew to its full length of eight inches.

With one hand pleasuring herself, the other reached out and cupped my throbbing nuts. Despite being twins I stood a foot taller than my sister, and with being so well endowed, her hand could really only hold onto the one nut at a time. A shiver ran down my spine as I saw her hand on my jewels, both from the fear of the pain that was about be felt, and from the fact that Lily was an incredibly attractive woman who was my age about to handle my junk. We both have sun kissed skin, light brown almost blonde hair, and eyes like sapphires, and where I was tall and broad, my sister was short and curvy. I was a swimmer for our high school swim team, and my sister was in volley ball. Her right hand closed around my left nut, and she lightly squeezed, a moan slipping past both our lips. I reached down to play with her firm boobs through her tank top, and while I felt the sensations from it, I tried to focus more on the feel of her boobs in my hands. After giving my left nut another, tighter, squeeze, she swapped to my right nut, and gave it a squeeze to match the second squeeze to leftie. Her hand pulled away for a moment before--

*Slap*

My balls got to experience what if felt like for Lily to spike a volley ball during a match. I was on my knees again before the pain really hit me, my face in Lily’s shoulder as I whimpered. A spike of arousal had me spurt pre-cum over my Sister’s bare thigh. I could feel she stopped touching herself a moment before both of her hands found my nuts.

“Stroke that big cock of ours Jake” I heard her whisper in my ear, and while whimpering from the increasing pressure on my nuts I obliged. One hand found its way to my dick, and the other to her perfect ass. My hand started to pump on my dick while I started to suck on her neck where it met her shoulder. The strength of her squeeze was increasing every second, and so was the speed at which my hand was moving. My hand on her ass lifted up before clapping down on her ass, causing it jiggle and her to gasp. An unfortunate side effect of this is that it caused her to tug on my nuts adding more pain and pleasure into the mix. Again I smacked her ass, and again she tugged on my balls, causing the tip of my dick rub the lower part of her stomach, just over her uterus. This time she tugged down when I slapped her ass, causing the tip of my dick to rub over her clit, and that marked the end of it. The pleasure from my most sensitive part rubbing on her most sensitive part while already riding the edge caused her to cum, which then triggered my own orgasm.

Rope after rope shot from the tip of my dick, painting the inside of her panties white. The whole while she kept squeezing the life and cum from my nuts. After a few minutes we both finally came down from our high, and I immediately cupped my nuts and curled up on the floor in front of Lily. I looked up at Lily and she was blurry, which is when I noticed I had started crying at some point, but, even through the tears Lily was gorgeous in her post orgasm bliss. And that was when I realized I didn’t love my sister, I was in love with my sister.
