“Ok,” Mike nodded, “We’ll donate our sperm every night but you have to take over our dish rotation, ok?”
“No problem,” the girl said happily, “that means dishes every night, but if this works it’s a small price to pay. How do we do this?” she asked.
Matt looked over at the bedroom door, “Ok, mom comes in and tucks you in every night before she goes to bed. That will be our cue to come in and give you our protein.”
Mike got up, “It would help us if you were ready, you know, naked. Ok?”
The girl nodded eagerly. She was finally going to have boobs!
***********************************************
Matt and Mike opened the door, closing it before turning on the light. You ready?” Mike asked the naked girl lying on the bed.
Hannah nodded, “What do you want me to do? I assume you both will jerk off on my chest but it seems lazy just to lie here.”
The two boys stripped down, their cocks still soft. Mike spoke first, “It would be faster if you jerked us off, you know, gave us handjobs,” he nodded to his brother.
“Oh, and,” he pulled on the girl’s thigh, “open your legs up. I’m telling you, your pussy is so pretty, seeing it will make it easier to cum.”
Hannah opened her legs wide, then even wider hearing her brothers both suck in air appreciatively. She wasn’t sure what to do but as she stroked both cocks they grew and grew some more. “Am I doing this right?” she asked.
Matt nodded, but Mike suggested something to make it better, “get our cocks wet, the lubrication makes everything feel that much better.”
Like this?” she spit on each hand, rubbing the saliva on her’s brothers’ erections.
“That’s good, but it would be better if you put our cocks in your mouth, you know, swirl your tongue around getting us nice and wet,” Matt suggested.
Hannah looked doubtful about this.
“You don’t have to, I mean it tastes no different than if you licked our arms,” Mike said.
“It’s not that, I was just wondering if I could open my mouth wide enough,” the girl said.
“Ah, well if you can’t you can’t,” Mike said helpfully, “A lot of girls can’t do it, but the ones that can get asked out a lot.”
Hannah decided to try it and found she was one of the lucky ones that was able to take a lot of penis into her mouth. After she got both her brothers wet, she learned they liked it best when she stroked near the plump heads so she rapidly pumped her fists on her brothers’ cocks making sure to add a little grip by the flared heads.
Matt reached between his sister’s legs to feel her pussy which had opened up like flower petals and was glistening pink. He looked at his brother, “I think our sister is enjoying this,” he said.
“Maybe we should have negotiated for more than just dishes,” he grinned.
Hannah liked how her brother was touching her and found her pelvis was rocking against his fingers in response. She’d touched herself there but never felt anything. Perhaps her touching their cocks was the same thing, different was better. She’d washed between her legs a million times without it once feeling even a tenth as good.
Mike’s eyes were closed as his fingers found a nipple on his sister’s chest. She might not have boobs but she had nipples that puffed impressively when she got excited, almost like soft pink half-spheres.
Hannah was breathing heavily as she pumped the two cocks and wondered why just after going to the bathroom she felt like she had to pee. She looked at the two cocks, now leaking fluids, and up at the intense looks on her brothers’ faces.
Matt’s finger penetrated the tightest cunt he’d ever felt and groaned he was cumming. He felt his sister direct his cock towards her breast as he let loose the first spurt of sperm onto her nipple.
Hannah moaned as she felt the hot cream splash onto the ultra-sensitive pink tip. As her older brother splashed jet after jet of cream on her breast she felt Mike’s cock getting dry. Better wet it again, so she took the fleshy shaft in her mouth, but when she thought she’d stop, she felt her brother’s hand on her head so she kept sucking.
Mike felt his balls ache as his sister’s lips wrapped eagerly around his cock. “Ok, I’m going to cum,” he moaned and felt the girl pull off and rapidly stroke his cock as he exploded onto her other breast.
Hannah squealed happily as both her boobs were now splattered with boob-growing protein. The two men collapsed back as if they’d run a marathon as she rubbed the pungent cream onto her chest, making sure to just apply it in circles around her nipples. For a strange reason, she wanted to rub it between her legs but resisted. She looked at the two, “Thank you very much. I can see that took a lot out of you, so I’ll be washing your cars every week if you can do this every night.” She took her top and cleaned the sperm that splashed onto the bed wishing it hadn’t gone to waste.
Mike stood up feeling almost guilty but his car was dirty and he just hadn’t gotten around to it, “That’d be great,” he said. “You know, we can get with Larry and Joe and maybe a few other guys if you want to accelerate the process,” he suggested.

“You had to wash their cars also?” Emma asked looking at her friend’s chest.
“You should have seen them,” the blonde sighed, “They were panting and sweaty when they came. I think it takes a lot out of guys to make the sperm, and,” she patted her chest, “look at the results.”
Emma reached over to feel her friend’s breasts again, “I don’t mind dishes or washing cars,” she sighed. Without thinking, her finger was tracing the puffy nipple stretching out the girl’s shirt.
