As he finished shaving, his wife entered the bathroom. She put her towel within reach of the shower, took her nightgown off and opened the shower door. "Hey! I was just ready to get in there."
"You snooze you lose pal" she quipped as she stepped in and closed the door.
Oh well, he thought. That's what's nice about Saturday mornings. No rush to get anywhere in particular. Since he was already in only his boxers, he decided to just sit down and wait his turn. As the shower water started to run, he noticed something that he'd never really thought about before. While the pebbled texture of the glass enclosure made it impossible to see details, he never the less had an enticing view of her naked curves as she stepped under the spray to wet herself down. Facing slightly away from him, his gaze slid from her strong legs, to her shapely ass to a wonderful side view of a full breast highlighted as she raised her arms to run water through her hair. Maybe going second isn't so bad after all he mused as he removed his boxers and lightly began caressing his already rousing member.
As she turned to pick up the wash cloth and soap, she was surprised to notice him sitting on the floor. As with his view, the pebbled glass prevented her from seeing detail, but she could tell that his hand was languidly moving in his lap. "What are you doing?"
"Just watching."
"Watching what?"
"Watching you shower."
"I wasn't aware that showering was a spectator sport."
"Oh I don't know. I'm thinking it might be pretty popular."
He had frequently tried to get her to touch herself in front of him, but she had almost always refused, claiming she much preferred his touch. Only once had she masturbated for him, and then as quickly as possible. But this was different, she was just taking a shower she told herself as she lathered the cloth and began washing her arms and back. She turned to keep what she was washing out of the spray. Or was it to keep what she was washing facing her husband's gaze? The reality of the question struck her as she again faced him to wash her front. Her movements slowed as she ran the cloth over her stomach, now fully aware that he was clearly stroking an erection. Her movements became less about cleaning and more about sensuality as she brought both hands up to her chest. While one hand ran the cloth over and around her heavy breasts, the other trailed behind, caressing the lather into her skin. She took far longer cleaning her breasts than was strictly necessary, both hands now squeezing the full orbs and pinching the distended nipples. For the first time she realized how hot she could get just from having him watch her.
While he could see the color difference of her large areola, he couldn't actually see that her nipples were hard though he suspected they were based on the way she was clearly pinching and pulling on them. She turned to wash her ass, making a show of running the cloth down between her cheeks. She washed down the back of both legs, then turned and washed up the fronts. Finally, she spread her feet slightly and ran the clothe in between her thighs. Based on the way her hand was moving in her groin, he suspected she was getting more than just clean out of the action. A suspicion confirmed as her free hand came back up to squeeze her breasts. But all too soon, she rinsed out the cloth and hung it over the top of the stall. She got some shampoo and lathered her long blonde hair, her breasts bouncing and swaying with the motion of her raised arms. She repeated the process with conditioner, then rinsed herself thoroughly and stepped out.
He could now see that her nipples were indeed rock hard. From his vantage point sitting on the floor, he could also see that her inner pussy lips were swollen and distended, clearly visible protruding beyond her outer lips through the wispy pubic hair.
He stood up as she finished drying off. She dropped the towel and stepped towards him.
