Jake corrects his mistake

Eric and Janie's parents were out of town for the weekend and they had tidied up their room before leaving. It was a boring space with everything put away, but the attached bathroom was larger and nicer than the one in the hallway.

Eric and Janie showed little hesitation in stripping naked, but Jake stopped them and suggested that the bet applied to undressing. Janie pulled off Eric's clothing in a rough and careless way, then Eric tried to strip Janie without touching her skin much or being sexy about it.

As Janie stood in her bra and panties waiting for Eric to clumsily figure out how to open her bra, Jake wondered why he wasn't enjoying the show. This should have felt unreal to watch. Was this part too mild?

Jake undressed himself during this, and soon the three were walking into the bathroom. Jake was watching Janie's smooth back and perfect bare ass with only mild interest when the realization hit him: He had changed himself to be too casual about this.

"Janie," he said cautiously, "We should keep the part where you are supporting me. $5 says this will be even less awkward if I react however seems natural to me."

"Sure, Jake," Janie said in a bored way. "Now help me figure out where Mom & Dad keep the towels."

Jake immediately went rock hard, but the others didn't react. The three of them searched the bathroom, found no towels, and then looked in nearby drawers and wardrobes until they got the right one.

As with undressing, Janie took the lead in washing Eric. She worked from the top down but Jake didn't pay much attention to Eric at first. Janie looked amazing with her wet blonde hair hanging down and water running off of her firm mid-sized breasts. Jake got a pretty good look at her shaved pussy from different angles and she didn't react to him moving around for a good view.

"Janie," Jake said cautiously once he had seen every bit of her, "Boys don't always clean thoroughly enough. Make sure you get everything below the waist."

"Sure, Jake."

Janie took her time to carefully work Eric's cock, balls, and ass crack. Eric's small, limp penis didn't react at all. Eric had an annoyed but patient glare on his face, as though he was waiting in a long line at the supermarket.

They switched and Jake got to watch Eric rub his hands all over his flawless naked sister's perfect skin. Janie looked tense compared to Eric and clenched her jaw a bit when her brother's hands moved over her tits, ass, etc., but she didn't resist.

"Start below the belt, I'm getting blue balls," Jake said casually. "Janie, get my balls and ass really well. Eric, take the shaft."

The siblings began soaping up Jake as instructed, but they were aiming to clean him and it didn't last long.

Jake couldn't take it any more. He slipped his hard cock out of Eric's passionless hands and turned on Janie. Her eyes widened in surprise. Jake just said, "Turn." He grabbed Janie's hips and turned her around, with her cooperation, then pulled her ass toward him and began grinding between her muscular cheeks.

The sensation was overpowering and Jake had already felt about to burst. In less than thirty seconds he shot his load on Janie's back. He got a brief view of cum running down her back before she turned and looked him in the eye.

"Hmmmph. You're right. I expected much worse. Can you boys get this over with now?"
