The Monster – part 4 – by charlieflemming

Beth noticed that Jo was being a bit more touchy-feely than one might expect, “Um, can I ask you something?”

Jo only then realized what she was doing and put her hands back in her lap on the floor where she was sitting, “Sure, what?”

“What were you really doing with your brother at Make-Out Point the other day.”

Jack gulped and looked to his sister with a look that said, “You better not screw it up” on his face.

Jo smirked, “Oh, that’s easy. We were teaching Jack about women. That’s all.”

Beth bit her lip, she glanced at Jack, for one thing, she was very concerned for him. He always seemed fairly innocent. She was only worried that he might be being corrupted by his sister and cousin. She decided to voice her concern, “were you teaching him, um, something sexual?” She asked.

Jo shook her head, “No, just the dating stuff.” She glanced at her brother’s face and noticed him blushing, “Why does it matter?” Jo asked her teacher getting a bit annoyed.

“Because it’s incestuous, to say the least.” Beth put in, feeling that much was obvious.

Jo laughed, but really this was to cover up her otherwise shocked expression as she felt she was almost figured out for a moment, “Haha, what? This is my brother!” She said, “What we were doing was innocent enough… Um…”

Jack started thinking about the “date” then, mostly about kissing his cousin or moving his hand down his sister’s belly. The cock in his pants was starting to rise. Which was very obvious to Jo sitting on the floor.

Jack tried to hide it with his hands but Beth quickly noticed it too. Jack wished he was wearing a shirt because then he could at the very least throw the bottom over his crotch to hide it. Instead, he sat in that chair, a hot older woman to his side, his even hotter sister on the ground, both women staring at his steadily rising cock in his pants.

“Umm, maybe we should…” Jack started to say, only wanting to get out of there before he got more embarrassed, but it didn’t matter because the bell rung right then.

Jack grabbed his shirt and was out of the room in seconds.

That evening, Jo was out until late again. Mostly because Rose was hanging out with her all the time now as she tried to figure out who Jo’s “mystery man” was. It didn’t help that Jo was getting exceptionally hornier and hornier as well since she dumped all her boyfriends.

That was pretty dumb of me, Jo thought as she lay on her bed. She picked up her phone and considered unblocking one of those meatheads, ugh! They all just bore me! She thought as she dropped her phone on her chest Most of them won’t even go down on me and none of them care if I cum anyway!

That made her think of her brother, I wonder if Jack will be a generous lover… Ugh, he’s too immature to even handle a woman like me! I can’t believe we’re twins most of the time… Jo felt her pussy clench at the thought, I don’t know why I find us being twins so hot! It’s like… “We’re made for each other.” She said her final thought out loud.

But would Jack find it hot? Jo went on with her thoughts, Ugh! No! He’d probably find it disgusting like I’m sure Rose will if she ever finds out about it…God, Jack had such a huge boner in school today! Jesus Christ I’m so stupidly horny!

Jo picked up her phone and started going through her blocked numbers again. She decided she was going to text someone after all…

Jack was up late doing school work but was just about to turn in for the night and finish it in the morning when his phone beeped.

It was from his sister, which he found odd since he couldn’t remember her texting him so late at night before.

Jo: Hey. U up?

Jack shrugged to himself. He guessed after their “date” that perhaps she was feeling friendlier than before.

Jack: Yeah but I’m gonna go to bed soon.

Jo texted back immediately.

Jo: Sure you don’t want to spend some time with your sista?

Jack thought, that’s weird? She’s never wanted to spend time with me before… well, not before that date anyway… That made him think of that awkward kiss she gave him, and him catching her in bed with him the other night… he decided he wasn’t sure what was going on with his sister but he didn’t think he wanted anything to do with it.

Jack: I think I should probably just go to bed.

Jo: Come on! I just want to ask you something. 😉

Jo put her phone down on her chest again, wondering if the winky face was a step too far. But Jack texted back only a moment later.

Jack: Can’t you just text it to me?

Jo scoffed as she read it. He really doesn’t get it. Doesn’t he know that when a pretty girl tells you to jump you should say “how high?” She pondered it but decided her brother was just too inexperienced.

Jo: No. It’s too personal.

It took her about a minute to reply to that and when her brother didn’t answer right away Jo realized he must have gone to sleep.

She tossed her phone on the shelf of her bedside table. And laid on her side to feel bad for herself, but only for about 30 seconds before she decided to just use the dildo in her bottom drawer and forget about the fact that she didn’t have any boyfriends anymore, or that her brother didn’t like her the way she liked him, and just masturbate and forget about the whole thing.

As she grabbed her dildo there was a knock on the door. Jo hastily stuffed her sex toy under her clothes again. She bit her lip and hoped it wasn’t her mom and opened it.

It was Jack standing in the same clothes he wore to school. Jo, however, was in a red bra that showed off her impressive boobs and a pair of matching panties that hugged her ass. Jack already felt his cock engorging again.

“What are you wearing?” He said as if it was a shirt with a picture of his decapitated head on it.

“It’s no worse than a swimsuit,” Jo said as she grabbed her brother’s hand and pulled him into her room. She locked the door behind her.

Jack held his shirt down over his growing erection since his pants weren’t nearly enough to hide it. “Just what did you want to ask me?” He asked, annoyed. Trying not to look at her.

Jo felt her nerves rising, but she countered that by being extra confident. She grabbed Jack by his waist and turned him so she could push him back so he was sitting on the bed. His huge cock making an obvious tent that he covered with his shirt.

Jack was probably the most confused he’d ever been. And the look his sister gave him as she sauntered over to the bed made his cock twitch and he didn’t know why. It was because Jo’s face, especially her eyes, were ones that showed nothing but the pure lust that she had for her brother.

Jack considered trying to run, but then he couldn’t because Jo had straddled him. Her tone sexy legs on either side of him as she sat so she could look at her brother in his sexy eyes. She wasn’t sitting so close she was rubbing up on the dick in his pants but the tent was very obvious in Jack’s shorts standing between them.

Jo finally asked her question, “How come you really kissed Clara but for me, you were like kissing a dead body?”

Jack blinked, it was really hard to think with his sister sitting on him like that and he could practically taste her breath on his tongue, “Uh I, well, I um,” he said as he tried to think of anything but what was going on right at that moment. He gulped, “I just did to her what you did to me.” He explained, “I’d never kissed anyone before and-“
