"Honey, are you ready for your shot?" Mira asked her boyfriend.
Finn grimaced. He hated going through this every month, but the effects of the testosterone outweighed his fear of needles.
"Sure thing," Finn replied. "You got it all ready to go?"
"Ready when you are," Mira replied.
Finn stood up, pulled down his jeans, and stood with his back to Mira. As she swabbed the injection site with alcohol, he made sure to take his weight off his right leg so the injection wouldn't hurt as much. It also helped take his mind off the fact that his significant other was about to stab him in the butt with a needle.
"Okay, we're going in three... two... one..." Mira counted down before plunging the needle into Finn's glute.
Finn clenched his teeth but otherwise remained calm, remembering to focus on his breathing while his girlfriend slowly injected the thick liquid.
"All done," said Mira, removing the needle and disposing of it in the sharps bin. She picked up a plaster to cover the small drop of blood on Finn's butt. "Who's a good boy?" she joked, ruffling Finn's hair.
Finn rolled his eyes and groaned in mock indignation before pulling Mira in for a kiss. "Thank you, honey," he said as their lips parted.
"Anything for you, my love," Mira smiled.
Two weeks later Finn sighed as he sat on the edge of the bed, looking at his chest in the mirror. His binder seemed to be shrinking and it was starting to get difficult to put on. Mira stroked his shoulder from behind him on the bed.
"Everything alright, my love?" she enquired.
"Yeah, it's just weird. I've been so careful with this binder, but it's just been getting tighter and tighter these past couple of weeks," Finn sighed.
Mira shuffled over and started kissing her lover's neck. "It looks fine to me," she assured him.
"It's fine for now, but I'm worried it'll keep on shrinking. The extra pressure is already making my nipples super sensitive," Finn said as he turned towards Mira.
"Is that so..." she purred, before pulling Finn down to the bed and quickly moving to straddle his hips. Grinning, she pinned his arms above his head and began to nuzzle at his nipples through the binder. Finn moaned. Even through the stiff fabric he could feel his nipples hardening as Mira pressed kisses against them. "You want to take this off?" Mira asked, tugging at the bottom of the binder. Finn nodded eagerly as his girlfriend released his arms so he could shuffle the binder over his shoulders. His boy-tits sprang free, revealing his bare nipples. Mira wasted no time in mercilessly teasing them. She flicked one with the tip of her tongue, while gently twisting the other between her fingers. Finn gasped beneath her, bucking his hips. Mira responded by grinding down against him, letting Finn feel her growing erection as she continued her assault on his nipples.
"Fuck..." whispered Finn, running his hands through his girlfriend's golden hair. "C-could you maybe suck on my nipples a bit?" he stuttered, struggling to form words as his mind was overrun with pleasure.
"Of course, my love," Mira murmured, taking as much of Finn's breast into her mouth as she could manage. She sucked gently, letting the underside of her tongue roll over her lover's nipple. Finn let out an audible moan as fireworks lit up inside his mind.
"H-harder please!" he gasped. Mira obliged and Finn felt his soul almost leave his body. It was as though every nerve ending in his body had been transported to his nipples and every touch they received was electric. Mira switched her attention to Finn's other breast, lapping all around the nipple before beginning to suck deeply. She began to massage the surrounding breast, sucking rhythmically. Finn felt his breathing sync up with the pace of Mira's suckling.
Suddenly Finn whimpered and Mira felt him stiffen beneath her. She straightened up and watched as her lover's head rolled back and he let out a deep moan. Realising what had just happened, she pushed her knee between Finn's thighs and ground it against his T-dick. Finn writhed as the overstimulation brought him to a second orgasm. As his mind tried to recover, all Finn could do was collapse on the bed, panting.
Mira ran her fingers gently over Finn's chest and kissed his neck. She rolled him onto his side and spooned him from behind, pressing herself close against him.
Finn frowned; it was a couple of days after his T shot and he was feeling decidedly strange. His binder had stopped fitting altogether, and while his shot generally left him feeling full of energy, this time around he was oddly tetchy and tired. Mira had prepared and administered it as usual so he had no idea what this change meant, or if it meant anything at all. Hormones were weird at the best of times and trying to change them could make them even weirder.
He drifted through to the kitchen to ask Mira what was for dinner, then caught sight of himself in the mirror. Had his hips gotten bigger? His chest too? Finn realised that his problem with his binder was less likely to be it shrinking and more likely to be him growing. Finn made a mental note to have his T levels checked at his next appointment.
As he entered the kitchen, Finn absentmindedly rubbed his stomach. Mira was making lasagne and it smelled divine.
"Do you need help with anything?" Finn asked.
"It's just ready to go in the oven, but thank you," Mira replied as Finn walked over and kissed her on the cheek. They embraced and Mira playfully squeezed her boyfriend's butt, causing Finn to moan loudly, taking them both by surprise.
"You a little worked up there, love?" Mira giggled. Finn blushed and hid his face in Mira's shoulder.
"Shush you," Finn murmured, trying to stifle a second moan as Mira squeezed his butt again.
With their bodies still pressed together Finn could feel Mira getting excited beneath her clothes. The oven temperature gauge clicked and Mira pulled away, turning to put the lasagne in. As she turned back around, she saw Finn glancing at the growing bulge in her jeans and biting his lip. Mira flashed him a wicked grin and grabbed Finn's hips, backing him up against the kitchen counter. Finn quivered as Mira leaned in to press heavy kisses up his neck.
"You want something?" she whispered in his ear
"I want you inside me," Finn breathed, leaning his neck to one side as Mira started to suck deep marks into it.
