I was puzzled by Joe's memory loss, but it always seemed to happen in his sleep. I decided maybe the way to break his amnesia was for us to have sex in the daytime. We had to do it when there was no time for him to fall asleep and forget. I thought about it in bed on Friday night and decided the best time to start would be Saturday morning. That way, he'd be wide awake and have a whole day when he wouldn't fall asleep and forget.
I set my alarm and woke up early on Saturday. I took a shower, did my hair and makeup, and put on the sheer negligee that Joe had bought me. I went in the kitchen and made him coffee, scrambled eggs and toast and a glass of orange juice and put them on a tray. Then I knocked on his door and entered.
Joe was still asleep, with a single sheet pulled over him. I gently shook his shoulder.
"Joe!" I said, "Wake up! I brought you breakfast in bed."
Joe turned over and rubbed his eyes.
"Hi mom," he said, "Is that for me?"
"Yes," I said, "I made you eggs and coffee. Where should I put it?"
Joe sat up and the sheet slid down his bare chest. He looked at me and took in the sheer negligee. As he stared, still groggy, at my legs and breasts, I noticed something stirring under the sheet. An outline of Joe's erection appeared through the cotton.
"Where would you like it?" I asked him.
Joe slid his hand over the sheet to conceal his bulge, but that just made it more obvious.
"I could put it on your lap," I said, "but it looks like that might be uncomfortable. Should I put it here on the bedside table?"
"Yeah, thanks," Joe said. He glanced down at the sheet, "I just woke up like this, sorry."
"Oh don't apologize," I said, "It's natural. You're a young man. I'm sure it happens a lot."
"Yeah," he agreed, "It does, and I have to say..." he trailed off and looked away.
"What Joe?"
"Well... it especially happens around you." He looked at me and grinned wickedly. Then he dropped his eyes.
"Really Joe?" I sat down on the edge of the bed. My bare thigh brushed his arm as I crossed my legs. My nipples were sticking through the negligee and I was lubricating freely.
"Does it bother you? That you get excited around me?"
"Well... I don't know," he said, "It's embarrassing. Like, you're my mom. I'm not supposed to be that way around you."
I caressed his hair gently. "I know it feels weird Joe, but it's bound to happen if you're a normal male. I may be your mom, but you've never known me that way. I'm more a woman than a mom to you and you see me coming out of the shower and in my bikini and your body reacts. Do you want to know something?"
"What?" Joe said.
I pulled his chin up and looked in his eyes. "I feel that way too sometimes."
Joe's eyes widened. "Really?" he said.
"Yes," I said, "I'm a young woman and even though you're my son, you're a hot guy. I can't help noticing the bulge in your pants. No girl could. I get turned on too. So tell me, now that we're being honest, do you think about me when you're in bed at night?"
Joe looked away. The bulge under the sheet had grown. I licked my lips without thinking, and wondered if Joe noticed.
"Yeah, I think about you sometimes," he said, his voice a little husky.
"What do you think about?"
"Stuff..."
"And what do you do when you think about stuff?"
His cock was now a rigid pole, sticking through the sheet. A damp spot appeared at the head, making the cotton almost transparent.
"You know..." he said softly.
"Well Joe," I said, "you're young and you need to relieve yourself, that's ok. If it helps you to think about me, I don't see why there's anything wrong with that."
I touched his concealing hand and my fingers brushed the wet tip of his penis through the damp sheet.
"Do you need relief right now Joe?"
Joe's eyes widened. "Uh... yes ma'am, I guess I do."
"I guess I shouldn't have worn this negligee," I said, "Sorry, I wasn't thinking."
I sat there in silence for a moment. I could almost hear Joe's thoughts. "Is she going to jerk me off? Suck me? Fuck me?"
Then I smiled and said, "Would you like me to step out of the room while you take care of that?"
I acted like I was leaving, but Joe caught my arm and looked at me so desperately that I sat back down.
"You can wait a few minutes, I'm sure," I said, "I think this talk we're having is important. But you haven't asked me what I think about when I'm in bed at night."
Joe's hard on was now making a full tent pole in the sheet.
"What do you think about?" he said. His eyes were moving from my face to my breasts.
"You know," I said. "Stuff.
I ran my hands over my breasts and caressed my nipples until they were sticking out.
"You know the kind of stuff," I said, "But now I want to see what you do when you think about stuff."
I gently turned the sheet down, exposing his throbbing hard-on.
"Oh my," I said, "How do you tame a monster like that? Show me please."
I took Joe's hand in mine and wrapped his fingers around his cock. Then I held his hand as he began stroking it. I stuck my breasts out through the sheer black negligee.
"Do you think about these at night?" I asked.
Joe stared at my tits hungrily through the sheer nylon.
"Yes ma'am," he said, stroking faster.
"What do you do to them in your thoughts?" I asked. "Suck them? Cum on them?"
Joe groaned and I pushed my breasts out. He knelt beside me and held his cock against them as he jerked off. Then he shot big jets of cum and soaked my negligee. His cum soaked the nylon and made my breasts all wet and sticky. When he was done, his cock was still rigid.
"Goodness Joe!" I said, "I had no idea how much you needed a release! But now I need to take this off, I am soaked."
I slid the negligee over my head. All I had on now were the sheer panties.
"Now I'm cold," I said, "Can I get in bed with you and get warm?"
Joe pulled back the sheet and I climbed in with my back to him.
"Hold me and warm me up," I whispered.
Joe wrapped his arms around me. I could feel his big hard-on against me.
"Mmm," I purred, "You're so warm. I could fall asleep right here. Do you mind?"
"No," Joe said, "that's fine."
"Good." I said, "I'm going to nap for five minutes. Keep me warm. Ok?"
I closed my eyes and Joe held me. I let my breathing slow and soon it became more rhythmic. I was almost sinking into a deep sleep when Joe began touching me. His hands caressed my bare, sticky breasts. I smelled of cum and my nipples were puffy from watching him jerk off. I was so horny I could smell my sex and I hoped Joe could too.
I felt his cock get harder as he smelled my warm scent and touched me. He rubbed against me. Then he put his hand inside my panties. I got more excited and soon he slid his cock under the gusset of my panties. His shaft touched my lips, teasing me. I was a hot, sticky mess, waiting to be fucked.
Joe slid the tip of his cock inside me. He held still for a long sweet moment then he drove it all the way in. His head rubbed my G spot deliciously as he fucked me and I soon came, bathing Joe in my thick juice. It was all I could do to keep still and pretend to be asleep as I came and came on him.
Joe's thrusts got faster and harder until he shot his load in me. I lay there contentedly feeling Joe's cum dripping down my thighs.
After a long time, he pulled out and rearranged my panties. Then he lay still holding me. As the afterglow wore off, I acted like I was coming out of a deep sleep.
"Mmm, I slept so good Joe," I said, "I feel much better. Thanks for letting me rest. You are so warm and cozy to lie beside. But now I need a shower! Your breakfast's cold. Why don't you make more coffee and we can eat together when I'm dressed."
I wasn't taking any chances with Joe falling asleep. I pulled him out of bed before I took my shower.
We ate a hearty breakfast and then I suggested a trip to the mountains. I knew some secluded woods with waterfalls and rock pools where we could bathe. I didn't mention swimming as I didn't want to take swimsuits. Somehow I thought it would be more fun without them.
We dressed for hiking and set off on Joe's bike. We reached the woods after a two hour ride, parked the motorcycle and started hiking. We had backpacks with drinks and snacks and sunscreen in them. I wore a tee shirt, cut-off shorts, hiking boots and no underwear.
We hiked for an hour or so up to the first waterfall. We were both hot and sweaty when we got to the top. We climbed down to the wide rocky pool beneath and sat there in the sun, drinking water and eating trail mix and apples.
"That water sure looks nice," I said, "Pity we didn't think to bring our bathing suits."
"Yeah," Joe said, "It's nice and clear, but it's cold."
"I'd suggest skinny dipping if it wasn't weird to get naked in front of each other. There's no-one around and we haven't seen anyone on the trails. What do you think?"
"I don't mind," Joe said, "Sure! I'm game for skinny dipping."
"Cool!" I said with a grin, "Let's do it."
We undressed and looked at each other, a little shy at first. Joe's firm young body looked beautiful in the outdoors. I hoped he liked my tan lines. It felt good to be naked in the woods. A wild freedom rushed over me. I slid into the cold water and soon I was in over my head. Joe jumped off a rock.
The water was shockingly cold and after a few refreshing minutes, I climbed out onto a big flat rock and lay on my back in the sun. Joe stayed in about five more minutes, then he got out too. He collected our things and joined me on the rock. We lay still, drying off.
"The sun is so nice," I said, "But if we lie here too long without sunscreen we'll get burned, I'm going to put some on."
I rooted in my backpack and found the sunscreen. Then I stood up and applied it to my shoulders.
"Our tender parts are really vulnerable," I said, rubbing sunscreen on my nipples. Then I applied it to my white mound and rubbed it in to my shaved lips and clit. Now my body was all shiny and oily and my pussy lips were swelling open. I handed the tube to Joe.
"Want some?"
"Yeah," he said, taking it from me. He applied it to his shoulders, arms and chest and belly. The he looked down at his cock.
"You really want to put some down there," I said, "You don't want to get burned. That would be very uncomfortable!"
Joe squirted sunscreen on his hand and rubbed it around his neatly shaved cock. Then he applied it to the shaft. As he rubbed it in, his cock got hard and stood straight out, shining with the oil.
