AHHHH!!!!
Andrew rushed naked into the bedroom as soon as he heard the scream to find Dan laying naked on the bed, and looking at his crotch, a panicked expression on his face. Looking down to where Dan was staring Andrew gasped, Dan's balls seemed to have increased double in size from when he had seen them just last night.
"It must of been the pill!" Andrew exclaimed, walking over to Dan and looked closer at the enlarged testicles. "They look normal, just ya know, bigger"
Dan got out of bed and walked towards the mirror, checking out his lean body and big balls. "No wonder I was so hungry and lost weight, all that energy was being converted into growing my balls" He said as he lifted them up a bit in his hand, feeling their weight. They were about the size of baseballs each, compared to the small walnuts size they had always been since puberty. His dick above them, hard from the usual morning wood, was still the same above average size of 7 inches. But this made it look weird and out of proportion now compared to his big balls.
Dan starts to walk around to Andrew, feeling his balls sway a bit with the movement. "They feel quite heavy, and tight... and making me really horny"
Andrew starts fondling them, "Well I think they're kinda hot"
His touch starts Dan's hard cock dripping with precum, way more than he usually would make when turned on.
"Oh good I really need to cum, they feel so full!" Dan groans as he throws his lover onto the bed, turns him over and starts lubing Andrew's hole with his precum. Andrew gasps in pleasure as he feels Dan's cock enter him, and half turns to kiss Dan on the mouth passionately. Dan starts to thrust over and over again, until he finally reaches climax. He groans loudly as he cums inside his boyfriend, filling Andrews ass with cum. Way more cum than normal, his cock just kept ejaculating. Once he finally stopped, Dan lay next to Andrew and turned him around in his arms to face him in his embrace. Oddly he felt their bellies touching so looked down to see Andrew's bulging out a bit.
"Jeez, looks like you cum filled me up, it inflated my belly quite a bit." Andrew said as he notices too.
"Sorry," Dan said worriedly "I didn't know how much was in me."
Andrew laughed, "Aww don't worry, it didn't hurt. It was kinda hot actually."
"Man I'm really hungry, it feels like half my body mass was just cummed out of me. Is breakfast ready?" Dan asked as he hurriedly got out of bed.
"Yip," Andrew called out after him, watching as his naked boyfriend leaving the room, amused to see those large balls of his getting in the way of his legs as he walked. "It was almost done when you started screaming, maybe a bit cold now"
Dan saw the bacon and eggs at the table and quickly sat down. In his haste and unfamiliarity with the new size, he nearly sat on his balls. Wincing a bit he quickly adjusted himself so his heavy sack was resting on his legs and started cramming as much food into his mouth as he could with his fork. "Uhh you can have my food too hun, looks like you need it." Andrew said as he sat at the table too. Unlike Dan, Andrew was wrapped in a dressing gown.
"Thanks babe." Dan replied with his mouth full, and continued to eat.
"So I guess it is probably best to not take any more of those pills then aye? I meant seeing you with nuts that size is pretty hot, but what if they keep them growing? How big could they get with one pill a day for a year?" He glanced down to his bloated belly, "and I don't think I could have handled any more cum inside me babes haha."
Dan looked up, as worry sets in, "Ah, actually the contract I signed stated once I agree to be part of the experiment I cannot stop until the year's trial is up, and that includes making sure I take the pills once a day."
"Yeah but this is clearly a major side effect, surely they can let you stop."
"No," Dan interrupted, "They said no exceptions, and if I breach my contract then they can sue me for a lot of money!" He paused, taking another bite of bacon. "Nah it should be fine, it's probably a new fertility drug, and the pills just keep me at this size."
"Ok, if you are sure babes" Andrew said skeptically, as he kissed Dan on the check. "Anyway, I need to go to the bathroom, it feels like you shot a gallon of milk up there." Andrew stood up and patted his small round budge as he left for the bathroom.
"Oh that reminds me." Dan spoke to himself as he quickly grabbed another pill and swallowed it.
