Your Cock Works For Me Now

My growth-spurt kicked in the summer I graduated from high-school. In three short months, my dick managed to grow from adolescent to truly MAN-SIZED proportions. One hot night in July, I found myself sitting in bed, just staring down at my very own seven-and-a-half-inch boner! With a mixture of pride and disbelief, I realized I could hardly wrap my fingers around it's rock-hard girth... My balls had grown by leaps and bounds too... they'd gotten heavier and hung lower... For the first time, I could feel their weight in my shorts when I went for my morning run.
Yeah, needless to say, that was the summer my balls started delivering man-sized doses of testosterone as well... a run on the beach generally became an embarrassing affair, as I would invariably spot some 24-year-old girl walking in a bikini, and PROMPTLY pitch a tent! I also discovered that my newly up-scaled equipment came with wildly up-scaled rewards... I just couldn't FUCKING BELIEVE how good it felt to blow my load! The whole summer, I couldn't stop thinking about my next orgasm... I mean, I'd been jerking off since I was 'like 13 -but that summer- HOLY FUCK!
It just seemed to HIT me! The REALITY of it.. unstoppable LUST...sheer PANGS of PULSING wanton greed for release! It was like I had this monster in my pants demanding -AND GETTING- my full attention!
I remember going home from one such run and jerking off to the fresh memory of some black bikini-babe, and almost being in TEARS for how good it felt! I MEAN IT! I couldn't help it! One minute, I was imagining this gorgeous girl's lush black tits just bouncing out of her bikini...all slippery and shiny with her sweat... the next, I was on my bed cumming all over myself! It was sheer bliss to just cum and cum and CUM! Such a relief! (A temporary relief, though. Fifteen minutes later, I'd be horny and have to do it all over again!) It took a few years for my childish mind to grow into my manhood; In the meantime, my dick truly got the better of me.

I moved in with my sister and her room mate Kelly the summer after I graduated High School. I was going to be at the same college, so it made sense- at least until I could find an apartment of my own. I didn't have a girlfriend at the time, and didn't really want to be working all summer; I liked surfing and just bumming around on the beach... That's when I had the idea of signing up to be a sperm 'donor'. They actually pay you 150 bucks per ejaculation, and they have you sign a contract that says you will visit the sperm clinic at least 3 times a week. Their only rule is that participating men abstain from ejaculating for at least 24 hours prior to visiting. It seemed easy enough; I passed their entrance examination, as I was free of STDs, and could really cum when I wanted to. (Honestly, not that hard for a horny 18 year old guy to do, especially if you shut him into a room with lingerie posters on the walls, and shelves of porno mags and DVDs! I actually felt like I'd found my calling in life! I was making bank, considering my last job was as a 5.50 per hour dish washer at a cafe!
My luck changed, though, when I made the mistake of bragging about how much I was making to my sister and Kelly. They were both in the nursing program, both single, and both extremely broke. I was helping with my share of the rent, but Kelly seemed a bit pissed-off at my apparent ease at getting through life by virtue of my dick!
"Must be nice for you. All you ever HAVE to do is JACK-OFF!" she said. My sister, who obviously didn't want to be part of the conversation, ducked out, rolling her eyes.
"Well... I mean, it's not easy all-the-time.." I explained with earnestness. "I have to hold out for a full 24 hours before going. If I ejaculate within a day, my sperm count will be down, and they'll know... they'll only pay me half as much..."
"I see. So you'd be out a little of your 'fun-money'? Poor boy."

I laughed
