Through the thin, white material of Cindy's blouse, Jim saw his daughter's plump young nipples pressing against the material with each rise and fall of her well-developed tits. His heart thumped and he swallowed when he realized she was braless. His cock started to swell in his jeans, and he quickly slipped into the house, easing shut the screen door behind him. He was stunned to see Cindy without a bra, and he was shocked at the effect it had on him.

He glanced back through the screen door and noticed the cover of Cindy's open paperback book – a color illustration of a man and a woman passionately embracing, the woman's tits bulging from her half-open blouse, the man sinking his teeth into her exposed throat. It shocked him to realize that Cindy read such dirty books.

So, my innocent little girl is growing up, Jim thought as he entered the kitchen for some lemonade. As he drank the lemonade, he thought to himself that he should have picked up a six-pack of beer while he'd been in town.

He went to the bathroom and pissed standing up in front of the toilet, something he hadn't done in the house since he'd got married. His wife had demanded that he sit down when he pissed so she wouldn't have to hear his piss splashing into the toilet water. She found the sound disgusting and uncivilized, she said, and that had been that.

He milked the piss out of his prick and found his hand applying a little extra stroking. His cock was still half-hard from his glimpse of Cindy's nipples through her blouse, and as he massaged his cock, it swelled and stiffened to a full, pleasantly throbbing erection. He felt wicked, and somewhat embarrassed to be beating off his cock like some teenaged kid.

He didn't think he'd jerked off more than a dozen times since he'd gotten married. His wife would have sent him to the minister if she'd ever caught him performing such a perverted, sinful, immature act, so he'd had to content himself with the once or twice monthly fucks she'd allowed him.
