“Hey Bro!” Nina said, bouncing into my room with the enthusiasm and energy of a perky 14-year-old.
“No.” I replied already knowing where this was going.
“What?”
“I said no. The only time you use that cutesy little sister voice is when you want something. The answer is no.”
“That’s not true!” she protested, even going as far to stamp her foot like a toddler having a tantrum.
“So you don’t want anything?”
“Well since you asked...”
“That’s what I thought,” I said, turning back to my PC.
“Okay, there’s this pool party this weekend and I have, like, totally nothing to wear. I just need to borrow some money so I can go shopping,” she spoke quickly, moving to sit on my bed in the process.
“Borrow? Really? So, let’s pretend I ‘lend’ you some money to go shopping then what? You don’t have a job so you can’t pay me back that way. I’m guessing the reason you’re asking me is because mom already told you no, so she’s not going to repay me either. So tell me, why would I give you money?”
“Because I’m your baby sister and you love me?” She said in the same cutesy voice again, eyes wide and biting her lower lip.
“Nice try, the goo-goo eyes don’t work anymore ... Hard pass”
“Please Mark! I’ll do anything! What if I do all your chores? For a month?”
“You don’t even do your own chores, why would I believe you would do mine. If you actually did your’s once in a while instead of leaving it for mom, she might be more inclined to give you some allowance.”
“Please Mark!” She literally begged, falling to her knees.
“Look, I’ve been working all week, because I actually work for my money, and I just want to relax, which I can’t do with you whining. So scram!”
“Pleeeeease!” She moaned, shuffling closer and wrapping her arms around my waist, hugging me while pressing her head into my chest.
“There are only two things that would get me out of this chair right now, and since you’re clearly not offering ‘me’ money, then it’s not gonna happen. Close my door on the way out.” I said, peeling her arms off and pushing her away.
“Well, what about the other thing?” She asked back to sitting on the edge of my bed?
“What?”
“You said there are only two things. The first one was money, so what’s the second?” She asked, seeing a glimmer of hope.
“Not something you can give me, so shoo!” I said point at the door, already past sick of this conversation.
“No. Tell me. Maybe I can?”
“Trust me, you can’t.”
“Tell me! I want to know!” She insisted.
“Fine! The only two things are money and sex, alright! You’ve clearly got no money, and you can’t offer me sex, so I have no reason to give you my hard earned money. End of discussion.” I almost shouted, totally done with the conversation.
“I mean, I could,” she said.
“Could what?” wondering why she was still here.
“You said I can’t. But I could ... you know. The second thing?”
The second thing ... wait. Did she mean...?
I paused my game and spun my chair to face her.
“What are you saying?”
“What if I ... if I did ‘that’ for you?” she does quietly, almost subdued.
This feels like a trap.
“Just so we’re clear. You’re talking about sex, right?” I asked warily.
“NO! ... Well, yes but not like real sex. What about a hand job?” She said, blood rushing to her cheeks.
Did my sister, my 14-year-old little sister, really just offer me a hand job?
I hadn’t expected this. But, that being said, maybe this was an opportunity? I looked at Nina in a new light. She has the same long blonde hair and bright green eyes as I did, her face still retaining some of her softer features making her look a little younger than her 14 years. Being a hair under 5ft and slender didn’t help.
However, the tight t-shirt stretched across her chest and the tiny pair of daisy dukes showing off her legs painted a picture of a more mature girl. She wasn’t the awkward little kid anymore. Not-quite-handfuls making the shirt tighter, and a firm little butt popping out her skirt was definitely something I hadn’t really noticed appearing on my sister before now.
Maybe I could make this worth my while.
“A hand job? Please. I can do that myself, and probably better than you can. A blowjob however ... I could pay for that?”
Nina bit her flip again in that coquettish way I suddenly found attractive. A half and half mix of nervousness and excitement. I did wonder how sexually experienced she was. From how quickly she offered to give me a hand job, I guessed it wouldn’t have been her first, but a blowjob...
“I want £80.”
“£80? No way, I could get laid for 80. I’ll give you £30.”
“£30. I can’t buy anything for £30. How about £60?”
“Nope. £40, and you’re naked for the whole thing and I can cum on your face.”
“What? No! £55, and I take my t-shirt off, but you can’t cum on me.”
“Okay, Okay. £50, topless, no bra, and I can cum on your tits. Last offer.”
It’s stuck me at how odd it was to be bartering with my own sister for a blowjob. How many men could say they had done the same?
“Huhhf,” she sighed. “Fine. Topless and you can cum on my tits. Perv!”
To be honest I was still half expecting her to suddenly scream something along the lines of “oh my god, I did believe you actually thought I would do that! Just wait until I tell mom”.
Instead of that, Nina grabbed the hem of her t-shirt and hesitated briefly then pulled it up and over her head. She wore a baby pink bra underneath that contrasted nicely with her light skin and blonde hair. Her stomach was flat and held just a hint of abs, her hips just slightly flared and her waist was tiny.
Reaching behind herself she unhooked her bra and let it slide down her arms.
“Damn sis. Where have you been hiding those?”
I’m usually a pretty good judge of size when it comes to a girl’s tits, I spent the majority of my teenage years staring at them. Well, to be honest, I still did. With Nina, I had guessed a b-cup, just enough or fit in the palm of my hand. However, released from her bra, her tits seemed to almost grow in size. Easily a C, they quite easily fill my hands.
“See, that’s why I need a new bikini! She said looking down, pressing them together by squeezing them between her arms then cupping and squeezing them in her hands.
“Nothing I have fits anymore.”
For a moment, she had forgotten she was half naked and squeezing her tits in front of her brother, and was about to suck his cock. She blushed deeply when she realised, and quickly dropped her hands to her sides. Taking a few slow steadying breaths, and after throwing a pillow to the floor, she dropped to her knees, her breasts bouncing as she shuffled closer.
“Are you gonna take your trousers off or what. I can’t exactly suck it through your jeans,” She said very matter of fact.
