April sat on the couch bored as hell wondering if she should even bother calling her boyfriend.  Her mother and father were gone for the weekend, again, and here she was stuck at home with her twelve year old brother Max.  There wasn't really a problem getting her boyfriend to come over it she could always have him show up after her brother was in bed, or bribe the kid with pizza tomorrow.  No the issue was more with the sex, not that he was bad in fact he it had been an awesome four months sneaking around with him while her parents had no clue.  He certainly pleased her way better than the other two she had been with and still did, it just, well it just wasn't exciting to her anymore.  'There's always trying out a more forceful male.'  Not that she was sure that would be a turn on, having claw and bite marks certainly didn't sound fun days later. 

“Bored with sex at sixteen.”  The mouse sighed out.  Only that wasn't true, she rubbed her legs together thinking about some of the more passionate stories she'd read on incest, not that she was going to do anything with her, well she didn't call her father scuzzy but he never seemed to be clean with gray fur that always looked like dirty white compared to her own well kept puffy cloud whiteness.  Of course his fur never had much shine either, that didn't stop her mom though, she knew the pair had been out multiple times on these weekend getaways but just thinking of him naked was a major turn off.  He wasn't even like those daddy/daughter stories where the man was old and worn but still had muscles to lift his baby girl up, she doubted her father could toss her on the bed let alone carry her down the hall to her room.

April had gotten lost in a little fantasy nearly ready to slip a hand down her pants if she wasn't startled by her brother coming through the kitchen, “Hey April.  Can you, umm, can you take the lock off the computer, Please.  I'll be really really good all weekend.”

“Max!”  The call was more surprised at nearly starting something her brother shouldn't see, but instead it was the kid who looked like he had just been caught doing something naughty.

Suddenly she started grinning, how hot would it be to mess around with her little brother.  The boy was barely starting to find girls, in fact he had really blushed hard the last time she had teased him.  The thought of him standing there naked make her want to truly finger herself, hard!  "Why are you smiling at me?" asked Max.

"Oh, no reason. Are you sure you want to play on the computer tonight instead of something else?”  Suddenly realizing his earlier question she grinned even harder.  “Something online you want to watch, or see?”

"I don't know."  The young mouse started,  “I just wanted to see if I could, um, get into that shooting game.”

“A shooting game?  You know mom would flip and I'm sure she'll check when she gets home, she might be even more upset if she found some porn site.”  April tried to keep her lips pressed together trying to sound stern seeing her brother bloom bright red under his white face fur.

The two were nearly a pair, noticeably sibs even with the four years age difference.  She patted the couch cushion next to her. "How about we talk instead.  We can talk about stuff you don't want to talk about in front of mom or dad." April offered

Max slowly sat next to her, taking his tail in paw. "Like what?"

"Like sex or something."

Max went wide-eyed and suddenly excited, "Really? Uh, okay I guess." The little rodent looked at his sister suddenly wondering what she looked like without cloths, not that he had seen more than a few pages torn our of a magazine his friend had shown him.  Suddenly he though of what he had been doing in bed at night and wondered if she did stuff too.

"So what do you want to know?  Any cute girls you like?”

"I don't know."  He said shyly sitting there still with full blush trying to get up just enough courage to ask a question.

"Hmm, I'd like to know if you play with yourself yet."  April spoke unable to stop her hand from sliding over and just touching his leg about his knee.

"Um, sometimes," she smiled with his little squeaking giggle.  "But I don't know, I mean I try but, what do I do if I get caught."

"What?  That's all you're worried about, mom and dad aren't going to go poking into your room after you go to bed unless your making a lot of noise.”  Her hand raised to pat his head and rub one ear getting him to grin back at her before he looked back between his legs.

"What do I if I play with it to long, once and I pee'd some stuff, I thought I was going to get in trouble cause I wet the bed.  I went to the bathroom for a towel but I couldn't wipe the stuff up it just got the sheets more wet."

'Oh GOD!'  April thought nearly getting a mini gush between her legs, "Silly, that's not pee, that's called cum. I can't believe you already do that."  She was nearly burning with desire thinking of how her brother could actually shoot.

"Cum? Isn't that a bad word?"  Max asked.  She smiled at her younger brother knowing the little mouse never like using any kind of slang or bad word like his parents taught him.

"It's your sperm sweetie. It's what boy's shoots into a girl to get them pregnant.”  Again that thought caused her body to burn, if this kept up she might just orgasm by rubbing herself though her jeans.  “It's perfectly natural, so do it as much as you want, though you might be better taking a napkin or some toilet paper to bed, just remember to throw it away or flush it when you get up." 

"Oh, okay,"  Max still seemed to be flush but finally got it out.  "Has a boy ever shot some in you?"

'Shit.'  April thought knowing she couldn't lie to him now, "Yes, but I use something to protect me from having a baby.  Mom and dad don't know I have been humping with some boys so don't tell anyone okay?"

"I wont." 

"That's my boy,"  April brought her paws up to his muzzle smoothing back his whiskers and gave him a kiss on the lips again causing him to blush hard. "You are so cute.  Well do you want to kiss some more?" 

Max nodded in delight, though doing so had pulled his head out of her hands.  The little mouse leaned towards his sister and puckered up.

April couldn't help going in and after a few moments of kissing she tried to slide her 
tongue into his mouth which caused the younger mouse to pulled back confused. 

"Don't worry,”  She giggled at him,  “Just touch my tongue with yours. Here I'll let you touch my boobs while we kiss."  With that she leaned back and  pulled her shirt over her head and unclasped her red bra tossing it over his shoulder across the couch. Max couldn't believe what was happening, his sister's bra slipped off and out popped her B cup tits hard and pointed out towards him. She put a paw up tweaking the tip on one side again nearly getting a gush of fluid between her legs, god she was so wet.  She smiled at her little brother who's eyes were now glued to her chest. "Go ahead, touch." 

Max instantly groped her, grabbing a little hard but feeling all over her soft 
breasts, light fuzz fur, and her small hard pink nipples.  April went for another kiss  unable to keep her own paw from rubbing herself through her jeans but Max suddenly jerked away and groaned, "Oh no!" His paws fled from his sisters chest to his own crotch covering his small prick. "I just..."

"You shot your load in your pants?"  April stated in surprise.

"Y-yeah, I gotta to go clean up,"  Max fled to the bathroom leaving April sitting there still in need.  Before the next second passed she had her own paw against her privates slipping two fingers of her paw into her soaked hole.  “God that was so HOT!!”  She cried out as her pussy gripped her paw and drenched it in juices.   A moment later she sat there panting from an excellent orgasm before removing her fingers from her privates and standing up slowly seeing an actual wet area on the couch where she had been sitting.  

More than anything April wanted to go bang on the door to the bathroom and drag her little brother out and to her bed.  She kept grinning as she passed that door on the way to her room.  There was still all weekend and she had no intention of scaring or totally overwhelming the little guy.  He definitely came, he was surely interested in doing more, and she was sure it wouldn't be difficult to find out how big he was.  They didn't even have sex and both of them had a serious orgasm, it could only get better from here.
