Jon sucks Jean's nipples.

"I knew it!" Jon announced, clearly pleased with himself. "I've seen the way that you've been staring at me! You want a chance at the Big J." His smile was a mile long, and he was inching closer to Jean.

"As if!" she said, going red in the face as she looked away from Jon. "You were just the first person that came to mind when I came up with the dare! That's all!" She glanced over at Michael. It looked like he was feeling pretty uncomfortable, too. She didn't blame him.

This had been exactly what Michael had been afraid of, that he would tag along with Jean just for her and her friends to start ignoring him as soon as things got going. The fact that he was being forced to see Jean 'not flirt' with the guy that she had clearly had her eye on for a while made things even worse.

Not to mention the fact that things were about to escalate. Jon was in front of Michael's sister now, with a sleazy look on his handsome face. Whether or not Jean was telling the truth about how this was what she had wanted, he looked openly excited-- Michael could tell by the look in his eye.

"Pop off those straps," he whispered in Jean's ear. It made Michael's skin crawl. "Let me see those beautiful nipples."

Jean shivered. Jon was a dick, but his voice was too nice to resist. Why did he have to be like this? Why couldn't he just be a nice, hot guy?

Still, she wanted it. Bad. As she had been told, she slipped one hand under each of the straps of her bathing suit and slowly drew them down. Her chest and her nipples were red from the warmth of the tub, and her nipples were sticking out. "Just do it already," she muttered, trying to hide her face.

Michael gulped. Was he really about to watch some strange guy sucking on his sister's boobs? What sort of weird shit had he gotten himself into? He could feel his stomach turning over. Nothing could have prepared him for the sight of his own sister's breasts, but seeing the two of them 'together' might be even worse.

Jon was taking his time. Michael hated that he knew this, but Jean's boobs were pretty small. That didn't seem to deter Jon at all, though. He was fascinated by them, rubbing his fingers over her nipples and biting his lip, basking in the anticipation.

"She said suck on them, champ," Lily piped up, leaning against Cassandra like two gossipy old women. "Not 'play with my funbags.'"

"Don't complain just because you're jealous," Jon said with a smile. "Although I'm not sure which one of us you're jealous of, now that I think about it."

Lily rolled her eyes. "Whatever," she scoffed, running her hand through her short black hair.

"She's right, though," Jon said, slowly bringing his head lower. "You did tell me to suck on these nice, hard nipples."

Michael grit his teeth. He could feel the hairs on the back of his neck sticking up. Why was Jean going through with this? Why was she just letting this happen? He really didn't understand what his big sister was thinking.

When Jon finally wrapped his lips around Jean's left nipple, all eyes in the room were on him. Lily and Cassandra both giggled, whispering to each other in voices that Michael couldn't hear. Michael just gulped, and held his breath. But Jean let a moan escape from her mouth.

Jon took his time, lovingly caressing Jean's nipples with his tongue and moving between the two. Michael didn't like the quiet groans that his sister was making. He didn't like that he could see her breast while Jon licked the other. He didn't like the way that Jean was breathing heavily, the way she held one hand on the back of her 'partner's' head.

"Time's up, eager beaver," Lily said with a bright smile. "Break it up, you two."

Jon pulled away, looking pleased. Michael didn't want to look at his sister, but he couldn't help but spare a glance. She wasn't looking at anyone, covering her chest with her hands as she let herself cool off. Between her fingers, though, Michael could see that her boobs were completely covered in Jon's spit.
