Chapter 3: A Busy Saturday and a Wet Sunday
Erotica Sex Story: Chapter 3: A Busy Saturday and a Wet Sunday - Molly is my only niece, and since my marriage ended before I could have any kids of my own, I’ve turned all my unused parental instincts toward her. When my sister Janice and her husband Gregg got divorced, I became kind of a surrogate dad to Molly. I was fine with that, even though I knew my feelings for her were gradually taking a dark turn. Then, one night shortly after her sixteenth birthday, she called and said she wanted to talk. I didn’t realize how much my life was about to change.

I didn’t sleep well that night, partly because of the amazing event that had occurred earlier, and partly because my conscience was trying to do its job. I usually don’t sleep late on Saturdays anyway, so I slipped out of bed while Molly was sound asleep. I took a moment to just look at her as she lay there. The sheet was pulled up to her chin, and for a moment, I saw the face of the young girl I had begun to think of like a daughter. It brought back memories of the night I had seen her napping on my sofa and fallen in lust with her, and probably led to us being there together.
As quietly as I could, I opened my suitcase and pulled out some clean clothes. I dressed in the bathroom, then went to the kitchen. Richard had a Keurig coffee maker and had a nice supply of pods, so I made a cup of starter fluid. I took my cup, went through the door in the living room that led to the porch, and sat down on one of the chaise lounges. I sat there for a while, sipping my coffee and watching the sun come up. I was still replaying everything that had happened on our ‘wedding night’ when I heard the door open behind me.
Molly came out, wearing a robe and carrying a cup. I hadn’t expected to see her up that early, and she did look sleepy. “Good morning sunshine. Did you sleep good?”
“Not bad.”
“Nice robe,” I told her. “Didn’t know you had anything that fancy.”
She smiled and said,” Maybe that’s because we’ve never slept together before.”
“Good point.”
She sat down in the chair next to me. Her robe slid open when she did that, and I saw her magical legs on display, all the way to the top of her thighs. “What do you have on under it, young lady?
Molly opened it quickly, revealing what I had feared - she was naked under it. “Christ on a crutch, Mols, cover yourself. We’re not on the tenth floor, people can see you.”
“Oh,” she giggled, “you mean those old farts looking for shells? Maybe I’ll give ‘em a thrill. Might make their day.”
I began to fear that I had broken more than just her maidenhead last night. She was becoming increasingly brazen. The quiet, shy girl I had always known seemed to be evolving quickly into a more typical, snarky, overconfident teenager, and it scared me. The way she had behaved in the restaurant last night apparently had been part of her emerging from her chrysalis.
“Get dressed. There’s an IHOP down the street. Let’s go have some breakfast.”
“Okay, gramps. You need a big breakfast. I plan on wearing you out today.”
Molly would never have spoken to me that way before. I had indeed unleashed a monster, and had the rest of the weekend to try to tame her–or just enjoy the ride.
After a big breakfast, we went back to the condo and changed into our beachwear; baggy swim trunks for me, and a daring bikini for my ‘bride’. I hadn’t seen Molly in a bathing suit in years, so it was a bit of a shock to see how much skin she was showing, even though it was normal for girls her age. She saw me staring and said, “What? You saw all of me last night.”
“I’m just thinking of all the horny boys ... and men ... who are going to be looking at you today.”
“Are you turning into a jealous husband?”
“Yeah, I guess so. Well, ready to show off your body?” I said.
“Sure.”
I drove the ‘Vette up and down the beach for a while. Molly insisted on sitting on the back of the passenger seat, waving like a beauty queen in a parade. Since the speed limit was ten miles per hour on the beach, I figured it was safe for her to ride that way. As expected, we got a lot of attention, some directed at the car but most at Molly. The shy kid I had helped raise seemed to really enjoy attracting all the admiring glances, especially those from the older guys.
After riding back and forth on the hard, white sand, I parked, and we did some body surfing. Even though I had grown up in Daytona, it had been decades since I had tried it, but the thrill of being pushed along by the waves quickly returned. Molly was acting like a rambunctious ten-year-old, venturing farther and farther out each time, until I had to put on my surrogate father hat again and told her to stay closer to shore. Reluctantly, she agreed. I think she was getting tired anyway, so that it might have been a pyrrhic victory.
It was starting to get hot, so we retreated to the condo. I didn’t want to mess up Richard’s place, so I told Molly we needed to shower to get rid of the sand and salt spray. I told her to go first while I waited on the balcony. She had another idea. “Come on, that’s a big shower. We can use it together. It might be fun.” I knew what kind of fun she meant, and it didn’t seem like a bad idea, so I agreed.
The shower was one of those fancy ones, with side-by-side shower heads, plenty of hot water, and good pressure, so it didn’t take long for us to rinse off the morning’s accumulation of sand, sweat, and seawater. I was about to turn my spray off and get out when my niece stopped me. “I’m disappointed,” she said, giving me a fake-sad face.
“Why?”
“We’re standing here naked, inches apart, and you’re not even getting a little bit hard.” She grabbed my cock as proof.
“Maybe the honeymoon’s over, and we’re just an old married couple now,” I joked.
“No way,” my bride protested. “I need more sex.” She sounded like a spoiled child.
“Keep holding me like that, and you’ll get what you want,” I told her, as my hand found its way to her mound and my fingers caressed her slit.
She giggled a little and started moving her hand faster. I knew if I just stood there and let her stimulate me with her soapy hands, I wouldn’t last long. I grasped her wrist and said, “Turn around and let me wash your back.”
Molly giggled and turned away. Part of her sensitive skin was beginning to turn pink from the day’s exposure to the harsh Florida sun, so I tried to be as gentle as I could. I started at the top of her shoulders, just using my hand, forgoing the rag she had handed to me. Since we had already rinsed off the sand and spray, my efforts weren’t so much about cleaning, but more of what I hoped was a soothing massage. Gradually, I worked my way down her back until my hands at last landed on her girlish bottom. At the risk of making a bad pun, if Molly’s legs were her best feature, her heart-shaped rear end wasn’t far behind. Seeing her asscheeks halfway exposed in her bikini that morning had put some juice back in my battery. Just to tease her a bit, I rubbed my now fully restored manhood in her asscrack, then moved it down between her thighs.
“Are you gonna...?” she started.
“Not here. Too dangerous. I’m just using my magic wand to clean your woman parts. Don’t move.”
I put soap on my shaft and started stroking between Molly’s legs again. I was moving along her slit, but didn’t attempt entry. It was just a teasing motion. When I felt her reach down and playfully tweak the head of my dick when it emerged from between her legs, I knew it was time to stop. I didn’t want to lose control. My first orgasm that day would have to wait. We rinsed quickly, then dried each other. In some ways, we really were beginning to act like a married couple.
After we got dressed, we were both hungry again. I didn’t feel like going out, so I ordered some burgers and fries from DoorDash. After that, I felt sleepy, so I told Molly I was going to take a nap. “What else are we doin’ today?” she asked.
“Later, we can go down to Ponce Inlet and watch the fishing boats come in. Then we can have dinner at one of the seafood restaurants. Then maybe we can come back and go to the boardwalk for a while.”
“Where the kids hang out?” she asked. Her tone was mocking, but I didn’t care. “Then we can come back and screw some more?” she asked, with a girlish giggle.
“Control yourself, young lady. Remember, you’re still kind of a kid yourself.”
“So tonight you can be a dirty old man trying to pick up a teenager? Sounds like fun.”
Molly took her phone and headed for the balcony to do whatever young people do for hours on end with that device, while I went to the bedroom and collapsed on the big bed. I dropped off almost immediately. I don’t know how long I had been asleep before I became aware that Molly had joined me, and not to take a nap. I half-opened one eye to check out what was going on and saw her lying next to me, with one hand burrowing into my underwear. Apparently, she had been doing that for awhile, because I was fully erect.
I kept my eyes closed, feigning sleep, wondering what she was up to. I felt her gradually lowering my shorts and briefs until she was able to bend down and put her lips over the purple crown of my shaft. So, there it was, her fascination with oral sex was coming out again. I decided it was time to let her know I was awake. “What’re you doing?” I asked.
“I’ve been watching some porn on my phone, you know, girls giving head, and I just wanted to try it. Since you just took a shower, I knew your dick would be nice and clean, so I thought this would be a good time.”
“And you thought I would be sleeping sound enough that I wouldn’t notice?”
“Nah, actually, I was just hoping that I would get to the point where you wouldn’t want to stop me before you woke up. Did I get there?”
“Long way to go, but if you’re serious, I guess I can let you explore. What kinds of porn were you watching?”
“Lots of stuff, but today, oh, deep throat and things like that.”
“Now, my young bride, how do you think your groom would feel if he found out you were watching sex videos on your honeymoon?”
“Well,” Molly purred, “if he was man enough, maybe I wouldn’t be watching porn.”
“Ouch! That kinda hurt.”
“So-o-r-r-y,” she drawled. “So, can we get back to what I was doin’? I need you to teach me how to do a good blowjob.”
I sighed. This was the girl I had taught to ride a bike, drive a car, and solve quadratic equations (that one we were still working on), and whose cherry I had popped, but teaching her how to suck a cock seemed like a step too far. Looking back, that seems like a crazy distinction, but that’s where my head was at that moment. My resolve not to cross that bridge didn’t last long. I looked down at Molly smiling back at me, her full lips just inches from my dick, and I caved.
“If you want to go back to pretending you’re asleep,” she teased, “I can try to figure it out by myself, but it might be kinda uncomfortable.”
“Okay, okay,” I said, “you win. But if we do this, you’ve got to promise to go all the way, cum in your mouth and down your throat. Anything less is cheating.”
“No prob,” she said, “that’s what I want too. I don’t want your ... stuff all over my face.”
I pushed my shorts and boxers down, and Molly finished the job by pulling them over my feet and tossing the bundle of clothing on the floor. “Straddle my legs facing me,” I told her, “so I can watch what you’re doing.”
After she settled down on my thighs, she looked up, an eager student awaiting instructions from her tutor. “Start by licking the shaft and head, like an ice cream cone. You want to get it good and wet. Makes it easier to put it inside your mouth. Lick your lips too, get them good and wet too.”
Molly went back to making my dick ready, moving her tongue in long root-to-crown strokes, first on one side, then the other, leaving a trail of saliva as she did. She was getting good at it when she suddenly stopped and looked up at me. “I’ve never had a good look at your balls,” she announced. “They’re kinda ugly. Can I lick ‘em or put one in my mouth?”
“NO! Don’t try that. You can find some overeager teenage boy to try that with, but I’m kinda sensitive about having someone inexperienced messing with that area. I had a bad experience when I was about your age. Kinda dangerous, you know?”
She giggled. “Yeah, I know about men and their testicles.”
“Okay, now back to your lesson. I should be nice and slick now, so put the crown in your mouth. Don’t go too far, you’ll gag yourself like you did last night.”
“I know, I know,” she complained.
“No talking. Your mouth should be full.”
I watched carefully as she leaned over and wrapped her pink lips over the business end of my manhood. I think a big part of why men enjoy oral sex is psychological - the sight of watching your cock disappearing between the lips of a cute girl, especially someone you have feelings for, adds a certain thrill to the physical sensation. Seeing Molly take on that challenge, without being forced to, was amazing.
Like a good tutor, I started giving her some positive reinforcement: “That’s it ... tickle the bottom with your tongue ... be careful with your teeth, try not to rub them against my tender flesh ... now, try to take a little more in, slowly ... let your mouth and tongue and even the back of your throat get used to the feeling ... you can use your hands too.”
After that, I decided just to lie back and enjoy myself. She really was doing a good job for a beginner, and my body was responding appropriately. It wasn’t long before I told her, “Okay, I’m getting close to cumming. Are you ready?”
She stopped and looked up again. “I think so. Do I really have to swallow it, or can I spit it out?”
“Just go ahead and swallow. I don’t want to have a mess on my belly, and I don’t think you want to hold it in your mouth while you run into the bathroom to spit it out.”
I guess I could have been a little nicer about that part, but part of me was trying to make the experience something she wouldn’t be in too much of a hurry to repeat. As I said, some of my thinking that weekend was convoluted, to put it mildly.
“Won’t it taste weird? And won’t your babymakers be swimming around in my mouth?” She didn’t sound as confident as she had before.
I laughed, “Well, I guess you’re about to find out. You don’t have to do much now to get me off, just put your lips over the tip and finish me with your hand. Don’t stop until I tell you. It won’t take long.”
I was right about that. The pumping motion of her hand gripping my saliva-coated shaft, combined with the feel of her soft, young lips, brought me to a climax that was surprisingly deep and long. Molly didn’t stop when my first spasm discharged into her mouth, but she did look up at me with her mouth still full of my dick and sperm, like she was hoping I would stop her. “Move your hand faster,” I told her, “there’s more on the way.” She started moving her hand faster and quickly elicited two more smaller spurts. “Okay, you can stop now,” I told her.
Molly immediately sat back, grimacing as she struggled to swallow the rest of the semen in her mouth. She gulped a couple of times, then opened her mouth to show me that she had been a good girl. She ran into the bathroom, and I heard her rinsing her mouth out. When she came back, I asked her, “Happy now? Curiosity sated?”
My new bride gave me a dirty look, like this had been my idea. I went to the kitchen and brought back two bottles of beer. I gave Molly one, figuring she had earned it. “God,” she moaned, “you’re really corrupting me. Champagne, fucking, cumming in my mouth, and now beer.”
“And you’ve loved every bit of it, right?”
Molly jumped on top of me and laid a big, juicy kiss on my lips. I tried not to think about what had passed over those lips a few moments earlier. “You’ve got to be the best uncle in the world.”
“Some would argue with that compliment, but I’ll accept it.”
