He chooses April

"Listen," Matt told his sister. "If you think you can persuade April to blow me right here in front of everyone, be my guest."

"Okay," she said. "Challenge accepted. Except I want something in return."

"I've already told you you're the best sister ever."

"Yeah, you did. You're super-sweet, you know?"

"I guess."

"Okay, time to get to work." Matt was surprised his sister was so enthusiastic about helping him with other girls. Given their... unusual... relationship, he would have expected some jealousy. For sure if some other guy came after his sister, he would be as jealous as shit. Instead, Karen not only seemed fine with him banging every girl in the school, she was his biggest cheerleader, doing her part to line them up to be fucked.

She really was the best sister in the world. Not to mention having a smoking little body.

"Hey April," Karen called.

The waitress appeared almost instantly. "How can I help?"

"Come talk to me for a sec."

"Okay."

The two girls wandered off and Matt turned to his mom and Amy... both of whom were looking at him disapprovingly.

"What?"

"You could have had either of us," his mom said. "How come you chose her?"

Oh, shit. Karen wasn't jealous but his mom was.

"Would you have been jealous if I'd had Amy climb under the table?"

"Well, a little. But that would be different. Amy is your friend."

"April is my friend, too."

"But... it's still different."

"Mom, I'm a teenage male. I'm going to fuck all the girls I can. But that doesn't make you any less special. You're my mom, after all. And Amy, I'm your boyfriend. Why would you be jealous when you know that?"

"I don't know. I guess I just am."

He nodded. "Well, that's one of the reasons I picked April. The two of you have to be more like Karen... start thinking about how you can help me bring other girls into the circle rather than how you might exclude them."

"But..." His mom's eyes filled with tears. "But that's so hard. Especially after we only made love once."

"And you haven't even broke my hymen at all," Amy said.

"I'll break your hymen before I break April's, okay."

She sniffed. "Okay. I guess that's fair."

Karen brought April back, leading her by the hand. "April has something she wants to show you, Matt."

"Your sister says that you don't think I'm good enough for your show."

"No, that's not true, April. You're a sweet girl who--"

"I'll show you sweet." She slid under the table while Karen took the seat next to Matt.

A second later, April's hands were fumbling with his zipper.

"Hot, huh?" Karen whispered.

He nodded as he undid his zipper and hauled out his semi-stiffy.

"If I'm doing it wrong, tell me," April said.

"Ouch, watch the teeth."

"Oh, sorry."

"I'll help her." Karen grabbed his scrotum with one hand and shoved April's head down with the other. "Take him all the way down your throat if you want to do it right, girl."

"Blug-fuag-glap."

With Karen massaging his scrotum and April's hands and mouth squeezing his cock for all it was worth, it didn't take Matt long to near completion.

"If you can't swallow it all, you're not ready for streaming," Karen said.

"Ah-dooo-eet."

He came, shooting his sticky mess into her mouth.

April emerged from under the table, opened her mouth and showed it was full of semen, then gulped it down. "See. I told you I could do it."

Karen got up and gave her a hug. "I'm sorry I doubted you. Matt didn't really say he didn't think you could do it. I just wasn't sure."

"Well I sure proved you wrong."

"Yes, you did."

"You'd better leave me a big tip for what you did."

"Absolutely."
