Will tried to push the insistent throbbing of his dick from his mind and the intense heat that was washing over him. However, it was always trying to grab his attention despite his attempts to focus on their game, not wanting to bring down their rank.
Fiona wasn't faring much better. She's try to adjust her tank top and her pants and underwear would feel tighter. She'd try to fix them, and her shirt would feel uncomfortable. At one point she'd tried to tug on her top and accidentally pinched her nipple, letting out a squeak. Will started to turn and ask what was wrong but Fiona called out a target for him in the game.
When the round finally ended Fiona backed out to the menu to prevent another round from starting.
"Damn I feel hot," Will complained, his discomfort outweighing his shyness, he peeled off his sweat soaked shirt.
Fiona glanced at her friend and her eyes widened. While she'd seen him without a shirt on when they went swimming, he looked much more alluring now. While not buff, his chest and abs were becoming visible. Fiona's eyes followed a single drop of sweat as it trickled down his panting body.
"Fiona? What happened to you," Will stared at the pair of B cups that were pushing out of her chest. Fiona followed his gaze to her own chest. She covered her chest and gasped at the jolt of please that shot through her. "Uh... I have to go," Fiona pushed past her friend, her hand accidentally brushing against his cock as she left and slammed the door behind her.
"What abo- and she's gone." Will sighed and then grunted as his penis pushed another inch larger. "What's happening to me," Will asked looking over his body.
Fiona threw open the bathroom door and shut it behind her. Panting heavily, Fiona leaned against the sink and splashed some cold water over her face. Staring at her reflection, she watched as a droplet of water trailed down her neck and disappearing between her new cleavage. "What the fuck-aah!" Fiona cried out in surprise as her chest pushed out further reaching C cups. "I'm getting bigger?" She felt her chest in disbelief at both the size and the sensitivity she felt. Then her hips widened slightly and her ass inflated further. "Damn!" Fiona tried to adjust her pants when she felt her whole body tingle. "Oh fuck me! Now what?" She got her answer as the floor seemed to get further away from her. Looking in the mirror, Fiona watched as her perspective heightened. Starting at 5' 6", she watched herself grow inch by inch, needing to use the sink to keep herself upright. And the tingling was becoming more intense at her eyes and ears. And on top of all of that, Fiona desperately needed to find a release for this need between her legs.

Will faced a conundrum currently. On the one hand he was at his friend's house. On the other, he felt like his dick was going to explode. Ever since Fiona had run out of the room, Will's dick had begun to throb vigorously and it felt like his when body was pulsating. He glanced down at his sweat slick chest and swore he saw his muscles expand with each breath. The crevice between his pecs deepening, his abs becoming more defined. He smiled as he flexed his arm and saw his bicep bulge. "I like this-aah!" Will felt his testicles grow inside his underwear and his decision was made. "Getting too tight. Sorry Fiona," Will gasped as he nearly tore off his pants and underwear and freeing his constricted crotch. It took him a few moments to process that the rod between his legs was actually his and not some dream. "Oh man! It's gotta be over 7 inches! I've doubled my size?" Will felt his body shudder as he wrapped his hand around the pulsing shaft. "Oh yeah." Will writhed with pleasure as he slowly began pumping up and down his shaft.
Just then the door was thrown open and a much taller Fiona was standing over Will. "Fiona! Look I'm sorry, but-," Will tried to explain but his explanation was stalled as Fiona lept into his lap and began to kiss him.
"Shut up and fuck me," she demanded, her eyes shifted to a ruby red color. "I want you to fuck me." With that, Fiona tore off her top and then ripped her pants off frantically. Her tits had grown to DD cups in the time it took her to remove her clothes and begin grinding against Will's cock.
"Oh God! Fiona! Your hair is changing."
Indeed, her hair had shifted from it's brown to a beautiful white.
"And that's not all," Fiona smiled and turned to show Will her ear had been pulled into a point. "Now help me."
Will didn't need anymore encouragement and latched onto her right fit and squeezed the left. As Will attended to Fiona's breasts, the transforming elf guided his cock to her folds and began to move.
Beneath Fiona's grinding ass, Will's hips widened, reaching close to his shoulder's width.
"Oh yeah," Will moaned, his cock pulsating larger another 2 inches. Beneath them, Will's legs began to stretch longer and merge together into a single appendage.
Fiona frowned as she felt something hard brushing against her inner thighs and saw the mass that was once Will's legs and the scales forming along it's length. Fiona found the almost emerald green top scales and light green underside scales almost hypnotic in their beauty. She looked behind her to see Will's continuously growing tail become covered in the scales. "You look sexy with a tail Will," Fiona increased the speed of her grinding.
Feeling a sudden spike of energy, Will wrapped his arms around Fiona and flipped them around so he was on top. "Not as sexy as you do in blue," Will complemented as Fiona's skin around her vagina began to turn a grey-blue color and spread to the rest of her body with each thrust. "My sexy little drow slut," Will teased.
Fiona gasped as her vagina was being stretched wider. "Wait wait. It's getting too tight," Fiona stroked his washboard abs and pushed him back. Not wanting to hurt her, Will complied and both of them watched as he extracted his dick from her sex. Fiona took the time to examine Will's crotch. His balls had been absorbed into his tail with only his cock remaining. The pair watched as Will's cock continued to vigorously throb and thicken.
"God it feels like I'm gonna blow," Will gasped and strained every muscle as his penis was split in two and formed a matching pair. Will hovered over Fiona, panting and smiling excitedly.
"I should be scared about all this, but," Will moved his now 25 foot, and still growing, tail around behind him.
"I'm living my fantasy right now," Fiona admitted. "I want to be wrapped up in your big strong arms and that sexy tail."
"Your wish is my command," Will grinned, lowering himself down to her and guiding his twins toward her ass and vagina. "Relax yourself."
