... too." Penny led him downstairs. "I guess you'll be sleeping on the couch, but you can change in my room if you want. I'll be upstairs."

"Thanks." Joe dropped his overnight bag just inside Penny's bedroom door, and she handed him a towel from the linen closet.

As soon as Joe had shut himself in the bathroom, Penny returned to her room and collected her beach bag, which she had already packed before breakfast. She took her shirt off and tossed it in the bag, and didn't dare look at her reflection in the mirror in her bikini; she did not want to lose her nerve now.

She knew she shouldn't, but there was no point in even trying to resist. On her way back to the stairs, Penny took a detour behind the chimney. Years before she'd overheard Cornelia and her partner in crime Kasie snickering about the view. Cornelia most likely still didn't know Penny was aware of it. Though she'd been back there to see for herself that spying on people in the shower was possible, she'd never done so before.

But they'd never had a guest like Joe before.

Joe's chest was just as toned and shapely as she'd imagined. His penis, emerging from a thatch that rivalled her own, was soft for the moment, but thick and very inviting. Penny swished her legs and wasn't surprised to feel her bikini bottom was a little wet.

Joe's bemused grin when he appeared in the kitchen doorway was a more than satisfactory consolation prize. Feeling no embarrassment at all, Penny stood up to give him a better look. "Ready for the beach?"

"Yes, and I see you are too," Joe said. "Sorry, I don't mean to stare or anything."

"It's fine!" Penny said. "If I didn't want you to see me like this, I'd have kept my t-shirt on." Already immensely enjoying the mild intimacy, she kept the conversation right where it was. "To tell you the truth, it's my first time ever in a two-piece. I figured I'd better get used to it in private before I go public."

"It does take some getting used to, going mostly bare in public, doesn't it? But you're gonna knock 'em dead," Joe said. "Let's go."

"You're sweet," Penny said, opening the door. "And you're right, it does take some getting used to."

"I ought to know," Joe said. "I don't know if Eric or Neeli told you, I was on the swim team all four years in college. I love swimming but I never did get used to everyone in the audience seeing me in a Speedo."

"Really?" Penny couldn't help herself - how could someone in such great shape feel shy about his body? "I mean, yeah, ...
