"I really could help with that," said Heidi, as Hannah wiped the semen off my chest, abdomen , and hips. She'd cleaned her wrist and hand first.
"Sperm is the last thing that needs to be near you while you're naked, Heidi," said her mother, sternly. "Don't push it. You get to see him naked. Even though you weren't supposed to see it, you observed how a man reaches completion. That should be enough for one day, don't you think?"
"I suppose so," said Heidi. "Get back into position, Sam. We have work to do."
I did and, after coming over to move this or that, she stepped back to look at me.
"That's as close as we're going to get it," she said.
"All right, then," said Hannah. "Now that you're back to work I have something to do downstairs."
"You aren't staying?" I asked.
"I can't babysit the two of you all day. And I trust both of you. I really need to get some things done. I'll be back later, okay?"
"I guess so," I said.
She went to the door and, just before closing it, leaned back in.
"Behave yourselves," she said.
"I thought you trusted us," Heidi said.
"I do," she said. "But I know how I feel right now, so I thought a little reminder couldn't hurt."
With that she left the room and closed the door. I had a lot to think about. One thing was that last little comment about how she was feeling. What did that mean? I knew she'd thought back to Desmond and the things they'd done as lovers. Then I had a fleeting thought about mothers who leave young daughters alone naked with much older, also naked men. Not your usual mother. Not by a long shot. But this wasn't a usual relationship, that I had with these women, and Heidi's boundless enthusiasm wiped away most thoughts of anything other than that she was doing what she'd said she wanted to do.
Then Heidi was standing right in front of me.
"Don't move," she said, reaching to gingerly grip the tip of my penis with her thumb and forefinger. She moved it from where it had been lying in a kind of lateral position, and made it droop downwards more. Oddly, I could see the logic in that. Before, it had looked like it was defying gravity. Now it looked tired and innocent. Of course it was tired, if not innocent, but I could detect nothing other than an artist's desire to get it into the right position. Maybe it was an excuse to touch it, but it was a good excuse, so I didn't say anything.
Time passed. Heidi was basically hidden behind the easel and my prick behaved itself. My mind wandered. Actually I got a little sleepy. Then suddenly Heidi was standing beside me again.
"Can I ask you a question?"
I thought this was an odd time to do something like that, but maybe she needed a little break.
"Sure," I said.
"Have you been doing the deed with my mother all these years?"
"What?" I gasped. "Of course not! We've never had sex even once!"
"Had sex?" Heidi looked shocked. "That's not what I meant."
"Well, then, what did you mean?"
"You know, making out," said Heidi.
"Making out?"
"Yes! Doing ... the ... deed?" she said, drawing it out.
"When I was growing up, doing the deed meant having sex," I said.
"Oh. Well, that's not what it means now."
"It doesn't matter. We haven't been making out."
"It sure looked like she knew what she was doing," said Heidi.
"She's done it before," I said, helpless to come up with anything sharper. "With your dad, I mean."
"Oh."
"Okay?" I said. "We all square, here?"
"I guess so," said Heidi. "It's getting hard again," she commented, calmly.
I looked down. She was right. I guess that wasn't surprising. She was naked and near me, and we'd been talking about 'doing the deed', whatever that meant these days.
"I'm almost finished, but it still needs to be soft," said Heidi.
"Great," I sighed.
"I could go get Mom again, but can I try it instead?"
"What? No!"
"Why not?"
"Heidi, you're sixteen. I'm more than twice that age. Not to mention it's illegal."
"Well, nobody would find out, so the against-the-law thing isn't really relevant," she said.
"It would be if your mother caught you doing it," I said.
"Okay, I'll go ask her if it's okay."
"No!" I gasped. "You can't do that!"
"Why not?"
"Are you insane? Your mother is not going to tell you it's fine and dandy for you to jerk me off, Heidi."
"Maybe she would," said my "niece".
"I don't think so." I noticed that my cock disagreed, because it had gotten mondo stiff again.
"Look. It's no big deal. Let me just get it soft again."
"I'll do it," I gasped.
"Okay. I'd like to see it from start to finish," said Heidi.
I know I should have made her leave, but things were spinning out of control again, so I just reached for my prod and started whaling away on it. Heidi stepped closer and leaned down to watch, interestedly.
"That looks kind of violent," she commented.
"It's not as violent as it looks," I panted, as if that made any sense.
"It makes me feel funny, watching," she said.
"No big surprise," I panted.
"Right here," she said, reaching to press two fingers to her mound just above her split.
"I'm pretty sure that's normal," I gasped. There was no way I could avoid thinking about the tunnel just below her fingers, or that my prick would love to try it on for size.
I groaned and lay back as soothing semen rushed through my prick.
"Fuck!" she whispered, which shocked me because I'd never heard her use that word before.
What made it even worse was that her fingers slipped lower and obviously pressed against her clit, even though I couldn't see it.
"Finish the painting!" I gasped, rolling back up and trying to get back into position. I didn't even worry about my spooge, which had splattered all over me again.
"Okay," she said.
But she got the wash cloth and cleaned me up with it first.
Heidi moved the easel so that light from the window fell on it more directly. This meant she stood sideways to me. Her nipples were straining away from her teenaged titties and, every so often, as she took a step this way or that, I was able to see her pudendal slit. It looked puffier than it had before, and I imagined her outer labia, which was really all I could see at that point, were also darker. I'm pretty sure the only reason I didn't get hard again was because I'd cum twice within the last hour and a half.
Another half hour went by before she finally stepped back and looked critically at the canvas.
"I guess that will have to do," she sighed. "I still don't think I got your penis right, but I learned a lot, doing this."
"I'm so happy for you," I said, sitting up. I admit there was a little sarcasm in my voice. It seemed like the whole world had changed that day. Starting with Heidi being so casual about getting naked in front of me. Later I would suspect she planned that all along, but I didn't think about it then. Then there were Hannah's words and actions, which seemed to have come from a completely different woman. That was followed up by Heidi wanting to emulate her mother's actions and the fact that she almost masturbated after watching me do that.
It was just a strange, new world, and I hadn't been able to process it yet.
It would only get stranger after we both got dressed and went downstairs for supper.
