Matt woke slowly

In his dreams, Matt imagined a beautiful woman was pressing her body against his. So, the transition from sleep to wakening was confused because, as he gradually became aware, there was, in fact, a beautiful, or at least extremely cute, female pressing her body against his.

His dick was wedged between Karen's ass cheeks and she was making little jerky movements that were probably what had awakened him in the first place because his dick was as hard as he could ever remember it.

His right arm had gone to sleep because Karen's head was still on his shoulder, reducing circulation, and his left hand still clung to her breast.

"Oh, yes." Karen's voice was a whisper and he deduced she was talking in his sleep. He also deduced that she was having dreams similar to his.

Her pelvis continued its little jerks and she moaned in her sleep, grasping his hand and pushing it harder into her breast. That wasn't exactly the way she'd taught him to handle a woman's breast but he wasn't going to argue. For one thing, if she woke up, he was afraid this would end abruptly and he wanted the end to be a happy ending.

Then she grabbed his hand and lowered it to her pussy.

He knew enough not to go straight to her clit. Too much sensation too early would certainly wake her and it might also piss her off. So he massaged her lower lips, gently dipping his fingers beneath the folds into the liquid warmth of her twat.

Abruptly she increased her range of motion, pressing against his hand and then ramming her ass into his dick while making little 'uh-uh-uh-uh' sounds.

He'd been near the edge just from having her ass clenching his dick but the added movement and the silky liquid feeling of his fingers in her pussy pushed him too far. He squirted his cum all over her ass.

"Fuck, Matt." Karen woke up cross. "What the hell." She jerked his hand out of her twat. "Haven't you heard of waiting for an invitation."

"You put my hand there."

"Oh." She rolled over to face him. "Really? Because if you're lying I'll find out and hurt you, you know I will."

Actually, he thought her bark was worse than her bite. She called him a perv and a moron but when it came down to it, she had his back every time. Still, it wouldn't do to let her know he'd divined her secret. "No, really. You stuck it there and, well, jerked off on it."

"Which is why I'm the one with an ass covered with boy-cum."

"I'm not saying you didn't jerk me off at the same time."

"God, you really are a pervert." Then she kissed him, hard on the lips. "I have to get up and shower off. No way I could explain this to mother."

"Explain what to mother." Their mother appeared in Matt's doorway.

Oh, fuck. How, exactly, was he going to explain this?
