Lose control

Unfortumately, Matt was too close already, the excitement of being this close to his naked twin, while being naked himself, with a finger slipping in and out of Lily's wet pussy. His cock started spasming in his own hand, and Lily gasped as her brother's hot sperm shot out onto her belly and breasts, liquid fire made her already hard nipples tighten almost painfully as they were bathed. Matt hovered over her, panting and embarrassed with his lack of control, but Lily just smiled as she watched spurt after spurt leave the tip of her brother's cock.

"Wow, you do like looking at your sister," she murmured, dragging a finger through the spunk on her breast and bringing it to her mouth. "I don't think dad came that much, even the first time we had sex. Didn't taste this good, either."

"You eat dad's cum a lot?" Matt asked, panting.

"Not really - as I said, dad's doesn't taste as good. Probably something he eats. Besides, he likes to cum... well, what he says is he likes to put it where it belongs." Lily started blushing again.

"He cums inside you?"

"Sure. He had me start taking the pill a few years ago, but until our last birthday, I didn't really know why."

"Our birthday?" Matt couldn't seem to follow.

"Sure, after everyone went to sleep the night of our eighteenth birthday, he came into my room, and, well, came into me I guess."

"And you didn't tell anyone?"

Lily scoffed. "It's not like he **** me. I'd had some pretty crazy thoughts before that, but I think that it's what I really wanted all along."

Matt shook his head. All these months since their birthday, and he had no clue his dad had been boffing his sister just down the hall. "Will... I mean, can I... we, I mean, do that too?"

"We'll see, but for now you better go clean up. I don't think either mom or dad would understand if they came in and found both of us naked, and me covered with your cum."

"Right," Matt said, almost throwing his clothes on before sneaking out of his sister's room and down the hall to his own. Matt had finally lost his virginity, but nowhere close to the way he had ever dreamed. He wondered what else he could do with this strange new power.
