It's Grand

Dan Jones didn't approve of how strict his daughter and son-in-law were on their daughter Lucy. She had just turned fifteen, but she wasn't allowed to date, or stay out with her friends past nine o'clock, and they made her go to a Catholic private school to keep her out of trouble, not that she ever had the chance to get into any. He was never that strict on his daughter growing up, so it must have all come from her controlling, know-it-all husband. Whenever Dan told him to lighten up, he'd just yell at Dan that it wasn't his business, but he hated to see how sweet Lucy was treated.

So whenever Lucy visited him, he always gave her whatever she wanted, as long as she promised not to tell her parents. He didn't appreciate being yelled at by his son-in-law. But Lucy never told her parents about the candy he gave her, or later the more revealing clothing he bought her that she hid for her parents. He liked to spoil Lucy, and since his wife died five years earlier, he did it much more than he had before. He loved to make her happy.

That weekend Lucy was staying with Dan, and he bought her all the junk food she always asked for. When her parents dropped her off, she was still wearing her Catholic school uniform. There was something about her white polo shirt, plaid skirt, and knee high socks that Dan always got hard over. He had even jerked off looking at slutty school girls on the internet. He felt bad about it after he'd done it, but he knew even though her parents thought she was so innocent and she certainly looked the part, she wasn't. He wondered if she knew how cute she looked in that uniform.

"Hi, Grandpa!" Lucy said, kissing Dan on the cheek and giving her a hug. Dan hugged her back tightly, noticing her A-cup breasts against his chest.

As soon as her parents were gone, she said, "what are we going to do today, Grandpa?"

"Whatever you want, baby."

Lucy smiled. "Do you mind if I change my outfit?"

"But you look so cute in that," Dan said, wishing she would keep it on all night.

Lucy rolled her eyes. "I hate this dumb uniform. I promise I'll put on something you bought me."

"Go ahead then."

Lucy took her suitcase into the bathroom, and when she came out, she was wearing a bikini top and a short skirt.

"That's awful revealing," Dan said with a straight face. He was sitting on the sofa and crossed his legs to hide his erection. He stared at her nipples poking through her small shirt. He had to force himself to look away so that Lucy wouldn't notice. "Aren't you a little uncomfortable?"

"You're the one who bought it for me." She spun around, and her skirt fluttered while she did it. "I thought you liked it."

"Well it makes you look sexy, but grandpas shouldn't think of their granddaughters as sexy," Dan explained.

Lucy grinned wickedly. "But I like looking sexy. Mom and Dad freak out if I look a little nice for boys. I mean, I've never had a boyfriend. I've never even seen a boy's dick." Lucy looked up at him and Dan's face reddened but he didn't say anything.

"Oh, Lu, you shouldn't be too anxious to get into adult situations."

She rolled her eyes. "I hate being treated like a little kid! Mom and Dad do it, please don't be like them."

"I won't, Sweetie," Dan said. "If you want to wear that, then you're more than welcome to."

"Thanks." Lucy sat down next to him. "I want to do more adult things. I want to, you know..."

"What?"

Lucy blushed. "I want to have a boyfriend, but I go to an all girl's school. I'm worried by the time I get to college everyone's going to be so much more experienced than me."

"You mean sexually?" Dan asked. Lucy nodded. "I thought you were waiting on marriage."

Lucy laughed. "I'm not a prude. Sometimes I get horny, you know, and..." Lucy paused. "I probably shouldn't be talking to you about this."

Dan uncrossed his legs, almost hoping Lucy would see the popped tent in his pants. "You can if you want to. Go ahead, I'm listening."

"Okay," she said. "I want to know more about sex stuff, you know, so that when I get a boyfriend I'll know what to do."

"Well, you can ask me whatever you want," Dan said.

Lucy hesitated, then said, "Grandpa, could I see your dick?"

"Lucy!" Dan said, but his dick twitched

"No, I just wanna see what one looks like in real life. Come on, it's just you teaching me something. Please? I won't tell my parents."

Dan couldn't say no to Lucy, nor did he want to. "Okay, Lucy, but only if it's our little secret." He slowly unzipped his pants, and his hard penis slipped out. He couldn't believe what he was doing, but his penis was throbbing in his hands and sticking straight up, and it was all he could think about.

Lucy stared at it in fascination. Dan was holding up his thick dick and looked at his sexy granddaughter. "You like it, sweetie?" Lucy nodded. "Touch it." Lucy hesitated, but Dan guided her hands to his shaft. "I want to teach you all about the penis. I want you to make me feel good. Then when you get a boyfriend you'll know what to do to him."

"Okay," Lucy said, moving her soft hands up his cock to the purple head where precum was already leaking out. She cupped one hand on his balls and slowly messaged them.

Dan closed his eyes. "Rub it. Yeah like that just kinda pull on it. That's good. Oh, Lucy, you're so good."

"It's so much bigger than I thought," Lucy said.

"Now, sweetie, I want you to suck my cock." He smiled when he felt her warm mouth envelop his dick. "That's it. Try to get as much in your mouth as possible." He watched as she bobbed her head on his cock. She gave a blowjob well for a first time, he thought happily. He stroked her hair until he could feel himself about to cum. "Mmm, swallow my cum, baby."

He released her load in her mouth, and pulled out to finish cumming on her face. He left a little dab of his white stuff on her cheek. He'd never cum so much in his whole life. "Oh my, Lucy, that was great."

Lucy nodded. "Uh-huh."

Dan tucked his limp penis back in his pants. "Do you mind the taste? Some girls don't like it but it's so sexy when a girl swallows."

"I don't mind it. It's kind of weird though. I could get used to it."

"You're on your way to becoming a good little whore. If you want, I have much I want to teach you."
