It was 'Hard' work

Matt reached for Karen's breasts but she batted his hands away. "Quiz one is a fail. Don't just go grabbing the girls."

"But you said--"

"I said I didn't want my brother to come off like a loser. So far you are. You have to build up to it."

She bent in to kiss him again, then moved his hands to her back.

Her back, Matt thought. Couldn't be much further from her boobs if she tried.

But Karen seemed to like it. She kissed him harder, then moved her hands to her neck and shoulders which was, Matt figured, at least getting to the right side.

Finally, she lowered one hand to her belly while forcing him to leave the other on her shoulder.

"You might compliment my belly now."

"You do have a great belly. If I wasn't afraid you'd hit me, I would compliment it all the time."

"Yeah, that's a pretty good compliment. I won't hit you if you sound like you mean it. Unless you do it in front of my friends or mom or, god forbid, dad."

"Yeah, noted."

"Now you can move it up." She demonstrated by bringing his hand up to her breast, then pushing it away.

"Huh."

"You were just going to honk it, weren't you?"

"Uh, yeah. Squeezing tits is--"

"Is annoying. Girls only pretend to like it because they're getting paid to be on porn channels."

"Ah." Good info considering that squeezing the shit out of those babies was very much in his mind.

"Now, when you don't get hit for touching her boobs you can move back."

"Okay." He slid his hand upward.

"If she lets you touch them, just leave your hands there. Don't go squeezing and don't rush to grab the nipples."

"But--"

"You failed the first quiz. You want to fail the second?"

"That's a no."

"Good boy." She kissed his nose. "Don't squeeze them, just think, you've got a beautiful woman lying in bed with you, letting you put your hands on her naked boobs. It's like you've died and gone to heaven. Right? So, why risk pissing her off. Enjoy the sensation, let her get used to the idea that you and her boobs go together."

"Got it."

"Okay, after a couple of minutes you can move to the next step. You can move your hands around to here--" she put his hand on the top part of her breast, "and then work down to the areola." She shivered when he did so. "They're sensitive so be careful."

"What about--"

"You pinch my nipples, you die."

"Ah."

"Gently."

He went gently.

She had to be enjoying it. Her breasts flushed and her breathing was definitely fast. All of a sudden, though, she pulled back.

"Okay, that's the end of lesson two. More later. Bye." She almost ran out of his room leaving him with a raging hardon and the guilty knowledge he'd just spent forty-five minutes making out with his sister and feeling up his boobs.

He grabbed his phone and his dick. He had to masturbate and he had to do it right away.
