"Ever think about fucking your little sister?"
"No."
"Well you'd better start!" Janet smirked...
...At least it wasn't his big sister. That would be a chore.

Laura arrived before the girls left and was sitting at the kitchen table with Janet when Steve came down the stairs.
He was more than a little nervous about this whole thing. He and Laura had been the closest of the siblings.
She was a year and a bit younger than Steve, a much smaller gap than the almost 3 years between Steve and his older sister Emma.
Neither of them could remember a time without the other.
Their mom had a vast store of photos of the two together, from the time they were toddlers right up to their weddings, both of them smiling in every one.
Brothers and sisters sometimes drift apart as their teen years approach, and not every teenage boy can call his sister his friend too. Steve could.
While he had honestly never looked at Laura in a sexual way, every single one of his friends sure had.
By the time she was a freshman in high school Laura had sprouted tits. Big, firm tits.
Of course she had boyfriends in school, but Steve's close friends knew she was off limits to them.
And the whole school knew that if you hurt Laura, Steve was going to hurt you.
Not many 16 year old boys with a car enjoyed driving their little sister all over the place, but Steve never felt like Laura was in the way, and all of his friends were used to seeing Steve and Laura show up together for events and parties.
Neither of them had thought it a bit odd when he drove her on her first date. Her prospective boyfriend sure did mind his manners the whole time, with Laura's tall athletic brother watching his every move!
Years later they both still enjoyed a laugh over that.
When Steve had gone off to college it wasn't long before one of his so called friends swooped in on Laura, and shortly after her graduation Laura was married.
In high school, Mike had been regarded as one of the handsomer boys, and Laura seemed to be truly in love, so Steve was good with it.
While Steve had always thought Mike was a bit of a "Pretty Boy", he was a nice enough guy and he and Steve got along well.
The closeness of the two siblings never faded. When Steve had met Janet and started dating her, he quickly introduced her to Laura and was excited when they immediately hit it off.
While he never overtly thought about it, his little sister's approval meant so much more to him than it would have meant to other men.
Laura had met a few "Girlfriends" before, and hadn't liked any of them.
It wasn't that Steve didn't already think that Janet was a keeper, but seeing the way she and Laura interacted like old friends after just a couple of meetings reinforced his rapidly developing love for his future wife.
Laura became pregnant with April at about the same time as Janet, and their already strong friendship grew ever closer over the years as they raised their girls together.
Mike and Laura had done well for themselves, Mike seeming to advance at his job much faster than a guy with only a high school diploma would be expected to.
Laura had gone to community college at night, and obtained a degree in business at her brother's urging.
She had proven her worth managing the office at Steve's business, so much so they kept her on after he had sold it.
There were no signs of trouble in their marriage, until one day shortly after April turned 15, when Mike was working late and Laura decided to surprise him with dinner.
To say she was shocked when she opened the door to his office to see him on his knees with most of the boss's dick in his mouth would be an understatement.
She had dropped the food she brought and stood, mouth agape, as her husband struggled to pull his head away from the strong hands pushing it down on to the throbbing cock in his mouth.
"He takes it in the ass too!" the boss laughed gruffly.
The divorce was quick but messy.
Laura had sought to strip him of his parental rights, but really had no grounds other than her own anger and only succeeded in obtaining supervised visitation for a few months.
She had done her best to keep the particulars from April, and although the subject was taboo in their house, she had a feeling that April knew the truth.
In the ensuing years both Laura and April had become a fixture in the big house with the pool in the back yard.
April never had to ask if she could spend the night, and almost every Friday evening the good times and casual conversation went on deep enough into the night that Laura availed herself of the guest room.
It had taken Laura three long years to get over the divorce, if in fact it could be said she truly was over it. Most days she was, but some days, well, not so much.
Beautiful as Laura was, 39 year old single moms sometimes struggle to get dates, especially busy career women like Laura.
And since she really wasn't looking for dates anyway, it's easy to see how she could let three years pass since she had last had sex.
Today she felt like it had been eons. Listening to Janet, April, and Jenny raving about her brother's thick juicy cock for the past month had totally broken down any resistance to incest she might have had, and now as she sat at the kitchen table with Janet, she was aware that her pussy was already wet. Very wet.
"Hey Sissy!" He said with a smile as Laura rose from the table to give him a hug. Of course it had happened before, but for the first time, he thought to enjoy the feeling of her firm pointy tits flattening against his chest, and also for the first time, felt his cock responded to the touch of his beautiful baby sister.
She gave him a quick peck on the cheek, and the three sat at the kitchen table making small talk while Jenny and April finished getting ready.
The change in Jenny and April in the last month was nothing short of amazing.
They had both started doing their hair and makeup daily, getting their nails done, selecting outfits to wear that featured their trim athletic bodies, and even shopping for shoes together to make Jenny look a little taller.
Jenny had started to care about the few little zits on her face for the first time in her life, and simply by using readily available products as directed, they were virtually gone.
She had permed her thin brown hair too.
It could no longer be said that Jenny wasn't pretty!
She even seemed to be entering her final growth spurt. In just one month her breasts had begun to swell a small but definitely noticeable amount, as had her taut firm little buttocks.
When Jenny wore a pair of tight black shorts and a white spandex half shirt that showed off the rippling muscles of her bare midriff to the store with her father the day before, Steve had more than once had to fight back the urge to punch someone for drooling over his daughter.
"Probably need to start wearing a bra, sweetie." He had whispered to her in the checkout line as his eyes drifted to the clearly visible outline of her firm little tits and puffy nipples.
She blushed and her braces gleamed in her smile as she gazed adoringly at her father.
It was becoming clear how her mature body would look, the fine butt and legs of her mother, and the pointy tits with puffy nipples from her father's side of the family.
And now, as the two young girls emerged from Jenny's room dressed and ready to go, Steve's eyes were drawn to a very large pair of pointy tits with puffy nipples from his side of the family.
He had to admit to himself, he liked what he saw.
Janet gave him a kiss and a wink as she and the girls headed out the front door to the car.
