You reached your hand down and gave your massive dick a few strokes through your jockstrap. Despite climaxing, you were still horny as hell and your cock was rock hard. You looked over at the research assistant, who was clearly checking out your body. She was one hot babe; the lab coat she had on hugged her slim hourglass figure and perky breasts perfectly. You knew you were supposed to meet up with your Coach, but your dick had other ideas.
"If you'll just follow me..." The research assistant smiled politely, trying her best to remain professional. You could see it in her sparkling blue eyes that she wanted you.
"Why are you in such a rush... Becky?" You asked as your approached her, reading the nametag on her lab coat.
Becky flushed bright red as you said her name, clearly aroused. You reached out and started to unbutton her lab coat, pleasantly surprised to discover she wasn't wearing a shirt underneath. You groped her large breasts through her black lace bra as she let out a little moan in pleasure.
"We're not supposed to...interact with the patients," Becky explained, clearly torn as she reached her hand out and ran it across your chiseled abs. "There could be side effects."
"I won't tell if you won't," You winked mischievously, sliding your jockstrap down and revealing your 8 inch member.
After another moment of hesitation, Becky got down on her knees in front of you, unable to resist. She parted her lips and gingerly kissed the tip of your swollen dick. You grabbed the back of Becky's head, running your hands through her long curly blonde hair. You slowly started to thrust your hips, sliding your dick in and out of her mouth as she continued to tongue the head of it. You closed your eyes and tilted your head back in euphoria, groaning in pleasure. Thoughts of large bouncing tits and wet pussies filled your mind as you continued to thrust your cock into Becky's mouth.
A loud tearing sound brought you out of your daydream. You glanced down to see that Becky's lab coat had torn apart, leaving her in just a bra and panties. Her shoulders had broadened out and her petite arms had bulked up with muscle, taking on a more masculine appearance. You expected to feel disgusted, but you found Becky's changes strangely alluring. Becky's chest continued to expand and broaden, tearing off her bra; her breasts were quickly absorbed into a set of defined pecs, her nipples shrinking down.
As Becky's changes continued, your own memories started to alter once again. You now remembered coming out as gay in your junior year of high school and hooking up with as many guys as you could. All of your past hookups with women were replaced in your memory by men. The thoughts of women that had filled your fantasies moments ago were transformed into fantasies of bulging biceps and thick hairy cocks.
Becky's panties ripped apart as her thin, dainty legs erupted with muscle and grew longer. A rock hard 7 inch dick emerged from the tattered remains of the panties, quickly followed by a hefty pair of hairy balls. A large Adam's apple grew in in Becky's throat as her hair grew shorter and darker, becoming a spiky dark brown. Becky's round face grew squared as her chin became more pronounced and grew stubble. Her lipstick vanished as her plump lips thinned out, her nose grew larger and her eyebrows thickened. Her bright blue eyes changed to a dark brown.
You felt your cock erupt with cum, and Brady hungrily swallowed your seed. Once your cock stopped squirting semen, you reached a hand down and helped Brady to his feet. Brady was your long term boyfriend and teammate, though the two of you were too horny and sex crazed to be exclusive with one another. In high school, Brady had been the star quarterback on your high school's rival, making you competitors. Now the two of you were finally going to be playing on the same team in college.
"Thanks for that babe," you whispered, leaning in and giving him a quick kiss, "That was great."
You could taste your cum on his breath as you ran your hand along his washboard abs and stroked his hard-on. "We should get going," Brady sighed reluctantly, "We don't want to be late for our first meeting with Coach."
