Ask her

"Well I might as well return the favour." She said. She poured the body wash into his hand, and started washing his abdomen, her face dangerously close to his erected cock. He didn't really feel

She moved up and washed his pecs.

She put more body wash on as she moved behind him, returning the favour with a back massage.

As she made her way down, he tensed up. It was time for the cheeks, which she just rubbed. Thank heaven, he did not like people, even his loyal girlfriend, touching him there. There had been this game they'd played in elementary where you put your hands together, and tried to shove them up the other persons buttcrack. He'd hated it and tried to avoid it, but him being as popular as he was, he couldn't always get his way.

She made her way down his legs, scrubbing the hairy limbs. She stood up, getting more body wash on her hands, and rubbed his arms. After finishing those it was time for the grand finale.

She put more body wash on her hands and kneeled. She grabbed on to his long, erect dick and twisted it.

Ow!

He moaned, but covered his mouth.

She pulled it up, down and on each side, causing him to moan even more.

That had felt a lot better.

She continued washing his no longer super erect dick, and shifted her attention to his balls. She yanked them down, and washed them for the last time. She stood up, and they kissed for another 5 minutes.

She hopped up, which surprised hum. They washed their faces, he washed his hair, and then they hopped out of the shower.

Luke dried himself off and then asked a question.
