Riley felt very very very naughty having just done that. She felt naughty the next day too. She took a very long shower to clean herself. It didn't help. She just touched herself in the shower. She still felt very naughty. She needed to fuck Lucas to feel less naughty about everything she had just done.

Lucas wondered why the usually timid Riley was so forward about wanting sex this time. But he didn't openly question why. It was better not to do so. He just went with it. Why would he question why his girlfriend was so horny? That was a sure fire way to make her no longer horny and not want sex any more. And obviously he didn't want that.

So he gladly got in between Riley's legs and started licking her pussy. She was very wet. Wetter than usual. Something must be up. But maybe she just really wanted to fuck and that was why she really wanted to fuck. Just because she was hornier than usual didn't mean something unusual was going on. He eagerly ate her out.

And Riley eagerly sucked his cock when it was her turn. But she very quickly wanted her boyfriend inside of her. Again Lucas wasn't going to complain about it. He wasn't going to say anything when Riley insisted on being on top. Again something the timid Riley didn't usually do.

Riley quickly got herself in position and got Lucas' cock inside of her. She felt relief. She felt a lot less naughty now that she had her boyfriend's cock inside of her. Now that she didn't feel naughty about what she had done any more she felt naughty about something else. She felt naughty about how demanding she was during this sexual encounter. She felt naughty being on top and she felt increasingly naughty as she was riding her boyfriend's cock. It was something she usually didn't do.

It felt good though. And she felt less naughty after a while. It was her boyfriend's cock. She really shouldn't feel naughty for riding his cock like this. She shouldn't really feel naughty for wanting to suck his cock so much. Her boyfriend. Her cock to use. It wasn't naughty to enjoy sex.

She had slowed down because of her timid feelings and avoided eye contact. Now she was speeding up again. Riding his cock at the same pace that her horny feelings had her riding his cock before. She was making more eye contact too. She was touching herself. Her niplpes and her clit as she was riding her boyfriend's cock.

And then she came on it. And then she felt naughty again.

"Can we- Can you fuck me from behind now?" Riley asked.

Lucas agreed to it. Of course he would. Why would he say no?

Riley bent over and Lucas fucked her. Riley prefered this position. It made her feel less naughty this way. Because she couldn't see Lucas. She couldn't see his reactions at all. Seeing them made her feel naughty. And this way he couldn't see her reactions either. She felt naughty and exposed when Lucas could see her face. She knew she really shouldn't. He was her boyfriend. She shouldn't feel naughty having sex with him. But she did. And she was working on stopping that. But it wouldn't happen right away. She had to work on it. However slow it might be.

"Riley I'm going to cum." Lucas said.

"Ok." Riley said. She didn't like it when Lucas told her that. She wished he would just pull out and cum on her back and clean her up and then they could just cuddle for the rest of the time. Riley would have to work on that too.

He did pull out. He did cum on her back. He did clean her up. They did cuddle the rest of the time. Riley felt better.
