After a couple of days, Donna finally recovered from the flu and Eric was able to come over. Fucking his cousin made him more energetic and confident. He wondered if Donna would notice there was something different about him. Donna was the love of his life, he couldn't imagine loving anyone but her. What he and Penny had going was temporary. Penny would go back to her family at the end of the year. In the meantime, he was just exploring his sexuality with her.

Donna and Eric talked for a while.

"You seem to be in a good mood", D0nna said, "Not nervous anymore about Penny being around?"

"Well now that Jackie broke up with Kelso,, it's not a big deal that Kelso cheated on Jackie with Penny and it's not a big deal that we didn't tell Jackie."

"I told you we shouldn't get involved, we always knew that wouldn't last long anyway."

"Yeah, and I've spent some time with Penny, she's OK, I can tolerate having her around."

"Cool, it's nice to have the relaxed and confident Eric back. I've missed him. He's very attractive and sexy."

Eric smiled at her. They kissed. It was the first time he had sex with Donna since he's started having sex with Penny. He was very confident and determined. He felt he was in complete control. They swiftly changed positions all that afternoon.

When it was all over they cuddled naked on Donna's bed.

"Wow Eric", Donna said, "That was…intense."

"It sure was."

"Very different than, you know, before."

"Well I haven't seen you in a while and I guess I've just thought about it for so long that I just knew what I wanted to do."

"Yeah I could tell you really missed me", Donna said and giggled.

"Well, you know Donna, it's…hmmm…"

"It's Ok Eric", Donna said, "We haven't been together in a while. So it's perfectly natural for you to be, you know, energetic."

"Yeah, I guess it is natural."

He kissed her, got dressed and left.

He got back home and went up to his bedroom. After a while Penny showed up.

"So you finally got together with Donna?", Penny asked.

"Sure did", Eric said.

"Oh my God, you fucked her, didn't you?"

"Is it that obvious?"

"Oh please, there's that big grin all over your face."

"Well…it was awesome!"

"Someone's getting cocky."

"Someone likes cocky guys", Eric said as he approached her and grabbed her waist.

"What's the matter, fuckboy? Fucking your girlfriend today wasn't enough for you?"

"Fuck no!", Eric replied and they lustfully kissed. Eric was thrilled. It was almost too awesome to be true. Having sex with two gorgeous girls on the same afternoon!

Soon they were both naked and Penny was in bec on all fours with Eric behind her.

"I see you like the fuckboy cousin pose", Penny said as she moaned.

"Fuck yeah", Eric replied as he thrusted his cock into his cousin's body.

"Not like with Donna, hun cousin?"

"No, you're much louder than Donna, I fuckin' love that."

"Oh yeah?"

"Yeah cousin, you cum so much harder."

They continued to tease each other as they fucked. Once again Eric felt overwhelmed by the intense pleasure. He couldn't believe that once again he was fucking his cousin, and once again, it was more intense than the previous time."

After it was all over, they lay silently on the bed.

"This is dangerous, cousin", Penny said after a long silence.

"What do you mean?"

"You're getting more confident and cocky. People will notice something different about you and wonder what's going on."

"You think I'm changing?"

"Look Eric, there were many guys who cheated on their girlfriends with me, OK? And when guys get lots of sex they become smug and cocky, which I admit turns me on. And they think they will never get caught, but they almost always do.

"So you think I'm becoming smug?"

"You're a fuckboy, cousin. Now, between Donna and me there's going to be a lot of sex in your life. It makes you energetic, it gets your juices flowing. You know what I mean."

"You think I'm behaving differently?"

"Yes. And eventually people will notice. I didn't care that much that all those guys got caught cheating on their girlfriends, but if we get caught…well, that would get us in much more serious trouble."

"I think I'm being careful", Eric said.

"Well, you can never be too careful."
