Karen met him in the driveway

"So," his sister demanded, "who the hell was that?" Karen wore jeans, boots, a riding helmet and what looked like a couple of bandanas knotted over her breasts. Her belly was bare and looked hot to Matt.

"That," Matt explained, "was Pam. She's Cindi's sister. She asked me to go out."

"You're making out with your girlfriend's sister?"

"Well, yes. Did you look at her? Pam is completely hot."

"Ohmigod, my brother has turned into some sort of sexual predator."

"I'm not a sexual predator. Pam needed a boyfriend because one of her girlfriends was giving her a hard time. So I agreed to help her out."

"In exchange for what?"

"Out of the goodness of my heart." He didn't mean it to sound like a question but it sort of came out that way.

"So who else are you dating?"

"Besides Pam and Cindi? Right now, nobody. Unless you count {if ****=true}you or{endif} Amy."

"You and I aren't dating. {if Karen-cum>0} All we're doing is helping each other out so we can be better girlfriends or, in your case, boyfriends. If we happen to get some enjoyment out of it, well, that's nobody's business but ours.{endif}"

{if Karen-cum>0}"Speaking of which," Matt said, "I could use some more practice on the whole pussy-eating thing. And, by the way, Cindi and Pam are both talking about going on birth control. If you want to help me with control and stuff--"

"You want me to go on the pill so you can use me for practice fucks? Seriously?"

"Uh, only if you want to."

"I... I'll think about it."

{else}"No, we're not dating. But we're friends and we try to help each other." {if ****=true}Matt could think of a lot of ways he wanted his sister to help him--definitely including getting some sexual experience before he went all the way with Cindi. She was a scientist in the making and did her research. If he didn't do his, she'd be disappointed.{endif}
