That night, I laid in bed and thought of the past day's events. The Thursday night I wished for a bigger cock. When I awoke Friday morning, I found my dick had sprouted from a small stub to a gigantic tree. Then unbelievably, after my older sister Sarah eyed my exposed bone under the dinner table, we had incredible sex in my room. I dumped my load into her tummy, inside her pussy and over her face and body.
"I just had sex with my sister! Incredible sex!" I thought. "Holy fuck!"
Next day, I awoke with my typical "morning wood." It was still huge and tented my bed sheets, but at least it hadn't grown any bigger. So yesterday wasn't a dream. I would normally have wack off but I needed to go to the can. Pulling on my MMA shorts again to at least hide myself, I scooted towards the bathroom. As I reached for the door, it opened from the inside. I stood face to face with Sarah.
"Hi Stud!" She smiled and grabbed me. She wore some pink flannel pajamas. The shirt was open and just covered her breasts. Her bottoms were short shorts pulled up tight and proudly displayed a rather deep camel toe. My cock jerked. "Mmm.. Is that a tree in your pants or are you happy to see me? Or both!"
"Sarah! Someone might see!" I scolded her and sidled by. "Besides I really need to go!"
I closed and locked the door behind me but heard Sarah call out. "Come to my room if you want to get rid of that thing!"
I shook my head and pulled down my shorts. I sat down but then realized that my dick was still too hard to piss sitting. I stood up and had to lean way forward so I could point it into the bowl. When I relaxed my bladder, piss came out in a torrid; like a race horse. And then taking a shit was no piece of cake either. With a hard-on, my dick pointed (dangerously) at my face. When it got soft, it would have dipped into the cold bowl, so I had to keep it between my knees.
After I showered, I needed to dress for breakfast. Baggy shorts alone weren't going to do so I ended up putting on some tight compression shorts first which at least held my dick against the inside of my thigh.
I got downstairs to the kitchen for breakfast and found Mom and Dad had already left to go shopping. Coffee still seemed fresh so I poured myself a cup. Food however didn't seem appealing this morning.
I was leaning back against the counter and took a sip of java when Sarah walked in. "Hack!" I choked. "Sarah!"
She had changed from her pj's into some sexy pink, lacy lingerie. Her bra cradled her breasts and barely covered her nipples while her panties were thongs that just hid her clit and some of her slit; the already wet string ran between her hairless, puffy pubes. "Hey, baby brother! Your sister has a job for you!"
She walked over to me and placed a hand between my legs again, cradling my balls. "I think you've got the tool that can fix my leak." She found my hardening member and ran her hand up and down. "My god, Timmy. I still can't believe how big it is!
Sarah pushed down my shorts and my dick sprang up free. She grabbed it with both hands and started to stroke it. It grew harder and thicker until it reached its full potential. She pointed it downwards and pressed her body against mine. When she let it go, my shaft was between her thighs. Sarah moved her hips back and forth sliding her definitely leaking slit over my cock.
"Fuck, I'm dripping so much." She begged. "Timmy... Can you fix my leak? Pleeeze?"
Not waiting for an answer, Sarah moved away and turned around. She bent forward from her waist as she reached between her thighs and pulled her thong string aside. Her juice was running down her thigh. "Put it in, Timmy! God I need your cock inside me!"
I put my coffee on the counter and moved into position behind her. I placed a hand on her ass and held my dick with the other which I used to rub my knob against her hot hole. My cock was glistening wet as I pressed the tip just between her lips. She tried to move back into me but I held her.
"Timmy, stop fuc'in teasing me and put it inside me... Now!" Sarah commanded.
I placed both hands on her ass and pulled her to me. Her cunt seemed to open up wide as I entered. It was incredibly hot as I watched my entire 12-plus inches disappear inside her. I started slow; pulling out half way and pushing it back in.
"Hard, Timmy! Fuck me harder" Sarah cried out. She was still bent over with legs spread wide and was now holding her ankles. Her long blond hair swept the floor. "Slam it in me. I need to cum!"
Obeying my older sister, I repeatedly drove my hips against her ass. Slowly at first and then faster and faster as I slammed into her firm and shapely ass. Her cunt seemed to squeeze and suck at me. "Oooo gawd, Sarah! I'm gonna cum!" I warned her.
"Yes! Now! Come in me now!" Sarah screamed.
All that pent up energy from not relieving my morning wood was released into my sister. "UuuuH! UUuuH! UUUuH! Oh F..U..C..K..!" I screamed out. "UUUUH!!"
"Yes! Oh fuck! Yes, Timmy! Dump your load inside me!" Sarah thrashed about as she orgasmed wildly and gushed. "Aaauuuu!"
We stayed in position with my throbbing dick still all the way inside my sister for a few minutes to recover. But with my balls now emptied, blood started draining from my member and I felt it get spat out of her slick hole. A big splash of cock sperm and cunt juice spilled onto the floor between her legs.
Totally spent, I let go of Sarah's hips and leaned on the counter to recover as I pulled up my shorts. Without my support Sarah collapsed to the floor. On her back with splayed legs and her thong still pulled to one side, I watched more fuck liquid pour from her gaping hole.
"Oh fuck, Timmy! I don't think the leak is fixed." Sarah smiled at me. "You'll have to try to fix it again."
Sarah struggled to get off the floor and took my hand to lead me to her bedroom.
This time on the comfort of her bed, we took some time as I fucked her in every position we could try out or think of. I lost count of how many times I made her cum; often as she sat just impaled on my dick as I laid on my back. We didn't stop until we were both spent and panting. She must have squirted a couple of gallons.
I looked over at the clock. "Shit! It's 1.30 already! We've been fucking for hours!"
"Right? I looked at the clock a little while ago between orgasms." Sarah tee hee-ed. "It just felt so good... so right to have you inside me, Timmy."
"Yeah. Nice, but I've got to go see Marsha." I managed to rise up from the soaked bed.
I had to have another shower to get rid of the sex stink Sarah and I were covered with. I grabbed a clean pair of compression shorts and put them on. Unfortunately they were shorter and came down less than mid-thigh. I grabbed a pair of button down jeans and a golf shirt. I felt a bit peckish after burning all those calories so when I finished dressing, I went down to the kitchen for a fast bite before going to see my girlfriend.
Sarah had changed into some loose fitting sweats and was on her hands and knees wiping up our mess from the floor. "Jeez Timmy. We really, really made a mess down here. I'll have to change my bedding too. They're soaked."
The front door opened. "Hi kid! We're back!" Mom called out as she walked into the kitchen. "I thought you guys would be gone by now... Sarah, what are you doing?"
