continue to part 5..........
"Good morning, momma!"
She blushed, then did a little pirouette that let me see her gorgeous, tight little ass. When she had turned all the way back around, I realized for the first time that her vulva was totally hairless – either shaved or waxed. Also, although she was tanned, there were no tan lines anywhere on her body. Her flawless tits and ass were uniformly browned like the rest of her.
Austin waved from the beach, squatting by the fire. Carl sat in a lawn chair with a beer in his hand.
When Mom came through the door, I heard her gasp through my headphones. To her, it looked as though my eyes were closed and I was listening to music as I slowly jacked my erect cock. Her eyes were riveted to my prick as she slowly walked to my bedside and placed the coffee cup on the nightstand. I thought she would leave, but she just stood there, only a couple of feet away from me as I continued to jack off.
"Good morning, Austin!"
She almost asked him if he slept well but realized the double entendre of the remark.
"Carl, isn't it a bit early for beer?"
With the sun behind her, she walked from the pier to the beach to where Austin and Carl were.
"WHOOWEE," Carl exclaimed and burped.
"What?"
His reaction confused her. Then she saw Austin ogling her open-mouthed. Shirley looked down and realized the slip dress was transparent in the morning sun.
"Oh my God! I had better go change."
"No, that's alright. You look good!"
Carl waved her over and pointed at a chair next to his for her to sit.
"Nice dress, momma," Austin said, winking.
The family ate breakfast and planned their day. The next leg of the riverboat trip would take them to a marina. The rental agent told them there would be a barbecue there.
"We've got booze and snacks. Let's just drift down the river. If we see anything interesting, we'll take a look. Austin, do you want to be captain today?"
"Absolutely!"
It was after 10 am after they had breakfast and broke camp. Carl was on his third beer, had snuck off in the woods, and did a joint. He was feeling no pain.
Austin steered the houseboat out of the cove and into the main channel while his parents basked on the sun deck. Austin applied enough power to keep them from drifting. An hour into the trip, Shirley came down.
"Austin, we need to talk!"
"Sure, momma! By the way, I love your dress. Did you wear it for me?"
"No! And don't change the subject. About last night...."
"That sounds like the title to an old movie."
"You're changing the subject again!"
Shirley smiled. Their banter was entertaining, better than her husband's grunts when she tried to talk to him.
"Well, it's hard to hold a conversation, pilot the boat, and ogle your body!"
"Stop!" Shirley laughed despite herself. "Look, last night things got out of hand and...."
"Take it off. I want to see what you look like naked in the daylight."
"I will not!"
She was indignant. This was just what she feared. Austin no longer saw her as just his mother; she was a sex object.
"That is not the way to talk to your mother. What happened last night was a mistake; fueled by marijuana and wine, it won't happen again."
Austin turned from the wheel and grasped a handful of her slip dress. Shirley briefly struggled, then surrendered to the inevitable. She raised her arms, and he pulled it over her head. She was naked in front of her son, sputtering.
Her pussy moistened, and her heart pounded in her chest. Carl was a few steps above them on the upper deck. There wouldn't be enough time to dress if he decided to come to the wheelhouse. The duality of fear and arousal was an intoxicant she would come to crave.
"You like absolutely positively amazing! You look like one of those Rubens models we studied in Art class."
"Didn't he paint obese women?"
"My teacher said he painted realistic, full-figured women celebrating the female form."
"Really? I never heard that. Do you think..."
"Austin!"
"Yes, Dad?"
"Put in over at that large sandbar. The chart says they serve lunch over there."
The sound of his boat shoes moved across the sundeck toward the stairwell.
"You had better get dressed, momma," Austin said, handing her the dress.
"Sweet Jesus! I forgot I was naked."
Shirley hurriedly pulled the shift over her head.
"OUCH!"
She started when Austin smacked her ass.
"Steer to the right, to the starboard!"
Carl corrected himself, smiling as he stood on the stairs with his feet visible in the wheelhouse and his head above the wheelhouse deck. He couldn't see the tableau playing out below him as his wife hurriedly pulled her dress on.
"You're terrible," she whispered to her son while rubbing her ass. Her pussy was so wet it was dripping, coating her thighs.
Carl came down the steps, patted Shirley's behind, and saluted his son.
"You're relieved," he said, smiling broadly.
"Yes, sir!" Austin saluted, chuckled, and stepped aside so his father could dock the boat.
He pinched Shirley's bottom when he passed her and went on deck.
The sandbar had an open-air bar, a dance floor, and a Common shower and toilet facilities. The family stuffed themselves with boiled crawfish, french fries, and beer. It was well after three in the afternoon when they backed off the sandbar and headed to their overnight harborage.
Austin was the designated driver for this leg of the trip and was allowed only two beers. His inebriated parents retired to the bedroom. He smiled as he heard their playful giggles turn to lustful moans. The sun was setting when his mother came into the wheelhouse barefoot, wearing only a mid-thigh robe.
"How far to the resort?"
Shirley yawned and stretched.
She and Carl fucked for the first time in weeks. While it felt good to have his cock in her again, she couldn't stop thinking about Austin.
"The GPS says this channel opens into the small lake where it is."
He glanced over at his mother and smiled.
"Have fun?"
"Yes, I did! Not that it's any of your business."
"Where's dad?"
"Passed out sleep, as always after...well, you know!"
"Take off the robe."
"Look, we never had that talk. I..."
"Take it off!" Austin smacked his mother's ass hard.
"Ouch," she exclaimed, rubbing her bubble butt with both hands.
Shirley's stomach quivered at her son's tone of command. She felt weak and uncertain of herself.
"Look, your father...."
Austin turned from the wheel, undid the tie on her robe, and pushed it off her shoulder. It fell to the deck in a silken heap. H turned back to the wheel.
"Stand next to me."
Shirley stared at the closed door to the cabin where her husband slept. Discovery would be devastating, changing her life forever.
She stepped next to her new lord and master. She wrapped her arm around Austin's waist, lay her head on his shoulder, and watched him maneuver the boat toward the dock. Darkness had fAustin, but the resort was brightly lit. They could hear music wafting across the water.
"Go out and toss the front halyard over the docking post."
Shirley reached for her robe.
"No, momma! Do it naked."
"What if someone sees me," Shirley asked.
"Thinking of how exciting that would be to have a stranger see you naked!"
"You're terrible," Shirley giggled, walking out to the boat's prow.
She tossed the rope over the post and stood naked on the boat's prow, reveling in the cool breeze, the driving beat of the music and her newfound freedom.
The houseboat rocked as Austin applied thrust, docking the boat. Around them, other craft were docked, some with their lights on, indicating people were onboard.
Austin walked up behind his mother and embraced her, cupping her breasts.
"You said you wanted to talk about last night," he said.
Shirley turned in his arms, wrapped her arms around her son's neck, and passionately kissed him, their tongues dueling. She thrust her Mons forward, grinding it against her son's manhood.
"Three things! I have another sheer slip dress like the other one. Should I wear it in the resort?"
Austin nodded, caressing his mother's ass.
"Two! I want to fuck on the beach tonight.
Austin nodded again.
"Hopefully, we can fuck for an audience," he added.
"I'd love that! Perhaps we could find a couple to swap with," Shirley said.
"Really! Where did that idea come from?"
"I saw it on one of the vids on your IPad. The mother and son became swingers!"
"Sounds like fun! Although, I'm not sure I'm ready to share you with anyone else yet."
"Except your father?"
"Yes! And the third thing?"
"I brought our ropes, handcuffs, and riding crop. Somehow please use those on this trip.
"Done!"
Austin spun Shirley around, smacked her on her ass, and propelled her toward the cabin.
"Get dressed and wake Dad up in that order! The night is young!"
