A/N: As always, the characters and actions taken by them are pure fiction

I woke up an hour later, with Lily still curled into my side, with a hand clenched on my swollen right nut, and considering the feeling in my gut, her hand had clenched some time ago. I leaned down and kissed her on the forehead, ghosting my hand on her side, in an effort to gently wake her up. I was awarded with bleary blue eyes blinking up at me.

“Good morning Sis.” I say before kissing her. Lily’s hand squeezes down a little tighter during the opening second of the kiss, but quickly releases as she feels the pain from the battered organ. After releasing my ball, her hand snakes up and grabs my hardening dick, giving it a light stroke.

“I know I said I was done for today, but if you’ve got time I’d love another round or two.” Lily says while increasing her grip and speed on my shaft. I give her another kiss before responding.

“There’s no need to try to entice me, I’m free all day. Have as much fun with our nuts as you want.” I tell her a moment before she lefts go of my cock and slaps my balls, sending them jiggling around in my sack. Another slap, this time aimed at my dick causes it to sway like a buoy. I’m tasting the inside of her mouth when a third slap lands home, and causes me to whimper into the kiss. We stay like this for a while, just making out with an occasional breath stealing slap to the balls.

“I want to try something new.” Lily says after clapping her hand around my right nut again, giving it a light squeeze. “here, stand up.” She says as she starts to get up all the while tugging on my ball. I follow her from the bed towards the wall. “Lean your back against the wall and spread your legs.” Lily instructs me while she starts to get on the ground in front of me.

“Sure thing Bossy.” I say with a teasing grin, only to yelp when Lily back hands my nuts. She huffs and rolls her eyes before laying on her back in between my legs and shooting her feet into my low hanging fruit. My nuts found themselves trapped in between her right foot and my pelvis, aching from kick they just received, but not being actively crushed flat.

“Either spread your legs more or squat down some, your choice.” Lily says while moving her left foot to rub my cock that was the same length as her foot. “huh, did your dick get bigger? I could have sworn my foot should have been longer.” I shrugged, I hadn’t noticed it get bigger, but I also stopped paying attention to that when it started to near the eight inch territory. Her foot pinning my balls to my pelvis applied a bit more pressure than a second ago. “Come on, use your big boy words and answer me when I ask you something.”

“I don’t know, I haven’t measured in years, I stopped measuring before it hit eight and assumed I capped out at earlier.” I told her, before the heel of her left foot mashed into my balls on her down stroke, forcing them out from under her right foot painfully.

“So you lied when you told me your size huh?” Lily asked before her right foot retracted and launched back into my balls, once more painfully pinning them to my groin. “I wanted to tease you about my size six being bigger than your dick, but here you go, matching up.” She resumed stroking the underside of my cock with her foot, on the up stroke her toes curling over the head, and on the down stroke her heel bumping into our balls, not as hard as the first time when she popped them out from under her other foot, but enough to make me start gasping on the down stroke. “This looked more fun than its turning out to be.” Lily pouted before with drawing both her feet and launching them into my balls, causing my knees to buckle and my full weight to rest on my balls for a moment before I regained my strength. “I want to see you jerk off for a moment while I think.” I didn’t need to be told twice.

I gripped my larger than previously thought cock and started stroking, though with her heels buried in our nuts, my stroking was obstructed. While my right hand was pumping, my left started to caress her feet, the only part of her I could reach in this set up. Even though I was actively jerking off, I wasn’t going fast enough or gripping hard enough to get to any kind of orgasm, and the pleasure from my link with Lily let me know that it was pretty much the same thing with the amount of pressure she was putting on our balls.

“I have an idea!” Lily said while pulling her feet again, and grabbing onto my balls to pull herself up, causing me to yelp. “Sit down, back against the wall and legs spread.” I followed her instructions and slid down the wall, legs spread and my balls resting on the vinyl plank floor. After looking at my balls and nodding to herself, Lily turned around shoved her ass into my face and dropped her heels on our balls, with our dick resting in between her ankles. “Feel free to hump my ankles while eating me out.” I felt her lean forward, not just in how her pussy was now pressing into my mouth, but also in how her weight shifted on our balls. I started to lick, while thrusting against her ankles. A few seconds after that Lily started to slightly bounce her heels, giving me a whole new feeling in our balls.

The mixture of pain and pleasure was intense, and after the last little activity, it didn’t take long for our third orgasm of the day to hit, with me shooting out over the floor and her toes, and Lily once more finishing over my face. During her orgasm, Lily’s little bounces more or less became full on stomps, grinding our nuts into the ground, and forcing more cum to dribble out the end of our dick and onto the tops of her feet.

Lily slid down my body to sit on my lap, and hooked her arm up to pull my head down to start making out again. Even though we had already gone three times today, I could feel my dick start to twitch once more, ready to go again shortly. With one hand holding my head, her other hand reached down and started to punch my balls, pretty softly compared to earlier this morning, but still hard enough that most people would have tapped out after a few. My hands weren’t idle while this was happening, my right hand started to play with her firm tits, while the left went to start to play with her pussy. After a particularly hard punch made me throw my head back and whimper in pain, Lily asked me a question that made my heart start beating like crazy.

“You got any condoms laying around?” I was up in a flash, holding against Lily me, even as she slipped off my left hand. I set her down and walked across my room and spread my legs and bent down to reach into the bottom drawer of my dresser, know I was about to--

*Thump*

Get kicked in the nuts, legs quivering, I kept myself open while digging through my--

*Thump*

Stuff to find my con--

*Thump*

Doms. I finally found them, but stayed in position for one more--

*Thump*

Kick, before standing up with wobbly knees and turning around with a silver square in my hands, that I promptly ripped open, pulling a white latex circle from within. Even though we hadn’t seen, let alone used, a condom since health class in freshmen year of high school, Lily was quick to snatch the condom from me and roll it onto our flushed and throbbing cock. The fit was snug, uncomfortable, but well worth the prize that awaited me.

“On your back, on the bed.” Lily said, in the same tone of voice as earlier. And I couldn’t help but tease her a little.

“Sure thing Bossy.” I was rewarded with a heavy handed slap to the nuts from my volleyball playing Sister. I cupped my nuts and moaned some, but laid down on my back, feet planted on the bed. Lily straddled me, facing me for a second, before she leaned down to kiss me. The kiss was quick before she pulled away and turned around, facing my legs. I wasn’t surprised, as this gave her the best access to abuse our nuts, but I was slightly disappointed our first time wasn’t going to be face to face. She started to grind her soaked pussy against my cock, lubing up the condom, before lining herself up and inserting me.

We gasped, the feeling of our pussy being filled wasn’t exactly new, as before we started this strange relationship, Lily had some toys that she had used a few times, but this was the first time our penis had felt anything like this. I had thought that Lily’s mouth was great, but this felt even better, and through the condom no less. I could feel our pussy stretching out over our cock, and I could feel the warmth and tightness of our pussy spreading before our cock. The only thing that prevented our first time from ending before it could really begin was the punch that Lily launched into our nuts, cause even though a masochist she may be, the biological reaction to getting sucker punched in the nuts pulled me back from the edge. The unexpected attack caused me to buck up into her, hilting myself in one fluid action, bringing a euphoric feeling to our cock, and a very unpleasant feeling to our cunt.

I found myself sitting up and hugging Lily from behind, rubbing her lower torso while whispering apologies into her ear for the pain I could tell she didn’t enjoy just now. After a few minutes I could tell that the pain had passed, and I felt her hands on our balls so I slid my hands to hold onto her hips. She looked over her shoulder, and I could tell that she had cried some, but the surge of love I felt from her end of our bond when she saw me made me a surge of love too.

“Let’s get started for real now.” Lily said, while she started to rotate her hips. While the feeling in our cock wasn’t as good as when I accidentally clapped in, the feeling was much better in and on our pussy. After getting used to feeling our cock stretching out our pussy, Lily started to add some up and down motion, bringing our cock to new heights, and quickly tempered with a punch to our battered and sore balls. Before long, Lily was moving up and down the whole length, with me thrusting up into her on her downward motions. The abuse to our balls was getting harder and more frequent, with Lily landing punch after punch into our nuts, causing my hands to tighten on her hips. but as they started to line up with our increasing tempo, they started to build in the pleasure Lily was sharing with me through our bond. I could feel our end approaching rapidly, when she grasped our nuts and squeezed with all her might, sending us both over the edge, with me filling the condom wrapped around our cock, and Lily gushing over my crotch. I felt Lily let go of our nuts and flop back into me, knocking me over onto my back. My hands left her probably bruised hips to caress her sides and stomach.

“I’m glad you were my first.” I whisper into the crown of her head. I could feel her response to my words, a surge of love, satisfaction, joy and affection.

“I’m glad you were mine too.” Lily says back.

I wish that we could stay like this forever, but I had to take this condom off and throw it away, and after the morning we had just had, water was a must, so I reluctantly pulled out of Lily and set her down next to me and got up. When I looked down at Lily, my breath got caught in my throat.

I had always thought my sister was pretty, and recently I had begun to see her in a different light, and thought of her as equal parts beautiful and sexy, but right here and now in her post fucking flush, Lily was the most gorgeous woman in the whole universe.
