Joseph -- "Josh" for short, the twin brother to Stephanie. He begins thinking about his sister sexually and as much as he resents her he finds himself thinking about an opportunity to make her his constantly.
Prologue:
Stephanie never thought that getting banged in the library could be so exhilarating. She could barely catch her breath as her twin brother pounded her into the bookshelf from behind, and as she gasped for air behind her covered mouth Joseph continued to ram his thick cock into her dripping cunt. The sound of him pounding her hips, the feel of sweat and juices running down her legs, drenched her thoughts of sex endlessly. He then pulled her leg into the air and drove ever deeper into her.
"Josh", she quietly cried, "Not so hard, we can't be caught... please quiet down, or wait until we get home... I can't be seen like this, not with... Ahhh... not with my brother!"
Ignorant of her plea he dropped her leg and pulled her arms back, relentlessly ramming harder into her, driving himself to ejaculation.
"Please... not without a condom, you can't cum in me. Do you hear me, you damn idiot. Do you know what will happen... mmhm... if you... if you cum in me!"
He thrust hard into her and as his hot milk poured into her she became consumed in ecstasy. She thrust her hips into his, thoroughly relishing the feeling of his hard cock pumping cum deep inside her soaking pussy. He pulled her arms tighter towards him bringing her head back for a kiss.
"Joseph, you jerk... mmhm...don't you dare stop cumming..."
As the dream faded Stephanie sat upright in bed, her pajama pants completely soiled.
"Damn... damn,damn,damn,damn,DAMNIT!"
"What the fuck brain?! With my brother? That's how we're doing wet dreams now, really what the fuck, why? Why... did that feel so fucking good, holy shit."
Chapter 1 -- Why so infatuated?
I never really cared for my sister. No twin brother really does, when you have a twin sister that's all there is to it. You have a sister. She's there when you come home from school, she's there for every holiday, and she's in the bathroom every time you need it. She doesn't really go anywhere and you don't ever expect her to someday be gone. In short having a sister is annoying. But it's sometimes nice. Twin telepathy is a nice perk, sharing birthdays is fun, but your sister is your sister. End of story. So why did I get nervous when she was talking to a nice looking guy the other day, or want to go into her room because it smelled nice, and why, especially why, can I not get her out of my head?
Joseph slipped off his shoes near the front door, dropped his backpack in the hall and made his way to the kitchen for a drink. Basketball is rough, practice three days a week, a late bus to drop you home after your sister arrives so you know that she took the shower by now even though you're covered in sweat and need the rinse.
"
Damnit
,
I wonder if Steph did use the shower... she uses a shower puff right? That is what they're called right? "
He twisted the tab off the bottle from the fridge. Absent mindedly thinking shower thoughts. Shampoo, body wash... Steph's puff... Steph placing the body wash on the puff... Steph slowly lathering her arms...
"Shit! No, I shouldn't be thinking about that!"
He thought desperately.
