Assert control

"Janie, I bet you'd feel better if you were more chill about this 'personal cheerleader' thing." Jake paused to figure out how to make this a real bet. He hadn't thought it through, he just hated how Janie was talking to him. "If you don't like it, you can go back to being a bitch about it, but if I'm right you need to be really on my side."

Janie thought it over, then sighed and relaxed her posture a bit. "You're right, I'm too worked up over some tiny wagers. I'll try to cool it and see how it feels."

"Good. I bet $5 you wouldn't even mind letting me watch you change. It's less sexual than the dance you did last night." Jake was tense and his blood pounded in his head. This was a small **** against her for speaking harshly to him, but did he really have as much power as he thought?

Janie scowled, shrugged, and walked to her closet. She dropped her green bathrobe to reveal the bikini from last night. She took off the top and pulled on a boring beige bra without turning around, then dropped a long red basketball-style jersey over that. The jersey partly covered her ass when she stripped off the bikini bottoms. She replaced those with boring gray panties and then short-but-not-too-short denim shorts.

The whole thing was a little hot, but not like Jake imagined. Was that his fault for saying "less sexual" during the bet? Jake wasn't sure, but it was something to be careful of in the future.

Janie took money from a dresser and gave Jake $5. She shrugged as if to say, "Yeah, that was nothing," but she didn't speak. Then she walked toward the door.

Jake wasn't satisfied. He wanted Janie to feel influenced, to feel like Jake was in control, and asking her to "chill" was a step backwards. He opened his mouth to **** another bet on her but then he stopped himself.

He had a realization: He wanted Eric to submit, too.

Jake followed Janie to breakfast, thinking about his phrasing.

Breakfast was uneventful and Jake was lost in thought anyway. Eric was angry but he was hungry too, and there was an unspoken truce while everyone ate. Finally, as they finished, Jake made his move. "Eric, you overreacted last night. You're too tense, you obviously need to get off. I bet you wouldn't last 60 seconds with me stroking your dick even if you had to look at Janie's tits while I did it."

Both siblings blushed a deep shade of red and stared at Jake with open shock, but Jake wasn't done.

"And if I win." Jake paused dramatically and held up one finger. "If he lasts less than one minute? I make all our plans this weekend, right on down to details like how you both dress. If I lose, Janie makes the plans instead."

Eric and Janie were silent as they turned to face each other. Janie pulled up her jersey to her bra, then hooked her fingers under the cups to pull everything up to her neck. Eric sat on the kitchen table and unzipped his shorts, then stared blankly at his sister's chest.

Jake reached into Eric's fly to grab the flaccid penis. Eric was completely soft and Janie was looking away, they weren't enjoying this at all.

Jake was enjoying it completely. He was high on the power and his dick tingled where his shorts rubbed against his erection. There was no longer any doubt about who was in control.

Eric got hard fast when Jake started stroking and nobody even bothered to count the time. Eric breathed a little faster as the minute went on and Jake tried to aim at Janie's pert breasts, but 45 seconds later Eric grunted and bucked his hips just a little before dumping thick ropes of cum on the floor.

Jake stroked until it was over and then laughed in Eric's face. "Fuuuuuck man, look how thick that is, you were really backed up. I told you."

Janie covered herself and glared at Eric, still being required to take Jake's side. "You've always been such a gross little fucker. I can't believe you fucking shot all over the kitchen floor from looking at my tits. You disgusting little fucker, I can't wait to be back in the dorms now. FUCK!"
