“Probably, possibly. Who knows?” said Carl. “Time will tell. Caroline?”
“Yeah?”
“Did you mean what you said?”
“About fucking you? Yes, I did. I guess it will have to be when Mom’s not around, but yes, bro, your prick felt so good in my pussy I’d kind of like to welcome it back sometime, in a more shared way, I think.”
“You mean next time, if there is a next time, and if you’re on top again, I can actually feel your tits?” Carl said, laughing.
“Yep.”
“Good. For now, I’m going for a swim, to cool off. You’re getting me all hot again, and with Mom at home, well, you know.”
“Yeah, we have to behave.”
Caroline joined Carl in the water and they swam for a while, then got out and sunned themselves, Carl managing not to get erect while he was rubbing sunblock into Caroline’s back and legs. “And my butt,” she reminded him.
“And your butt,” he said, rubbing the sunblock in with a caress, admiring the firm muscularity of Caroline’s ass. As soon as he’d finished, Caroline rolled over and held out her hand for the sunblock.
“I’d better rub this into my tits myself,” she said, “else you’ll get turned on again.”
“I already am,” said Carl. “It’s only a massive effort of will that’s keeping me this soft.”
Caroline regarded the half-erect penis in front of her with a smile. “Lie on your stomach, Carl, and I’ll do your back, too.”
Carl lay face down on his towel, adjusting his prick to the most comfortable position. Least uncomfortable, he thought, amused, then groaned as he felt Caroline’s hands begin to rub sunblock into his back.
“Will you do mine when you’ve finished Carl’s?” Their mother’s voice took them both by surprise. Judy was standing next to them, a short robe covering her down to mid-thigh.
“Sure, Mom, just lay yourself down,” said Caroline, resuming her application of sunblock on her brother.
Judy shrugged off the robe and knelt on her towel beside Carl. She was wearing a blue bikini, modestly cut. About to lay herself down on the towel she paused, looking at the twins, gnawing at her bottom lip. She obviously came to a decision because her hands went to her back and in a moment she had discarded her bikini top, muttering, “Oh, shit! I hope I don’t regret this.”
Carl and Caroline gasped in surprise, for Judy had obviously decided to join them in their celebration of Nude Day.
“That’s as far as I go,” said Judy.
“Mom, you’re gorgeous!” said Carl, admiring the pretty sway of Judy’s breasts as she knelt beside him. Judy was almost as slender as her daughter, but with slightly fuller, slightly lower-hung breasts. Erect nipples, Carl noted as Judy lay on her front a yard away from him.
“Thank you, son,” she said softly. There was a high spot of colour in each cheek as she looked at the twins. “I nearly didn’t, but the two of you looked so good I just had to,”
“We’re glad you did, Mom,” Caroline said quietly. “You look great.”
“Thanks, honey. I kinda feel good, too.”
“Wait until you have a swim, Mom. That feels even better.”
“Later. For now, I’m just going to enjoy the sun and the unexpected afternoon off work.”
Finished Carl, Caroline began to apply sunblock to her mother’s back. She worked down to the small of Judy’s back, then put her head close to her mother’s.
“Mom?”
“What?”
“Are you sure you want to keep the bottoms on? You’re going to get sunblock on them. I can rub it on down to the top of them, and again on your legs up to the bottom, but it will probably spread. You’d be better with them off.”
Judy looked at Caroline, a wry expression on her face. “You’re trying to get me completely naked, aren’t you?”
“Yes, of course I am. It’s Nude Day, Mom, and you owe it to yourself to join in.”
“Sweetheart,” Judy said softly, “if it was just you and me, no problem. I guess I’m shy around Carl. I was embarrassed just showing my breasts.”
“Mom, by now Carl will probably be lying on a boner. Believe me, if I turn him over he’ll be the embarrassed one. So let me just untie these bikini bottoms and get you naked.”
Caroline reached for the ties on her mom’s bikini briefs. Judy’s hand came up to stop her but paused and fell away. When Caroline had loosened the ties, Judy raised her hips an inch or so and Caroline slid her mom’s briefs out of the way.
“There, now we’re all naked,” Caroline said softly. “Now we embarrass Carl.”
Judy reached out and stopped Caroline. “No, honey, let him be. You haven’t finished my sunblock yet. There’s still my ass and legs.”
Carl had heard very little of what his sister and mom had been saying, but he saw the bikini bottom come off and felt his prick give another little lurch towards full erection. Oh, shit, he thought, just what I need. He glanced across at his mom who lay with her head turned away. He admired the lovely curve of her back into her ass and the swell of her buttocks. A swimmer, like her children, Judy’s butt was firm and shapely. Carl groaned silently. God, I’d love to slip my prick between those cheeks!
The three of them sunned themselves for a while, Carl not daring to move because of his erection, until Judy eased herself up and sat back on her heels. There was a bright spot of colour on her cheeks when she caught Carl’s eye but she made no attempt to cover herself and he was able to admire her loveliness. For Judy was lovely. Fuller-figured than Caroline, but it only served to give her body a softness that the more athletic Caroline didn’t quite have.
Judy stood, and Carl was surprised to see that his mother, too, had trimmed her fleece. “I’m going for a swim,” she said. “Anyone else?”
“Sure thing, Mom,” said Caroline. “Carl?”
“No,” he said. “I need to use the can.”
In the pool Judy and Caroline swam quietly along together. Caroline glanced back over her shoulder to see Carl disappearing indoors. She chuckled.
“What’s so funny?”said Judy.
“Carl. Poor baby has a huge boner. Probably gone to jack off, get it to go down.”
Judy closed her eyes for a moment, the earlier vision of Carl’s erection coming unbidden to her mind.
“Mom?”
“Yes, sweetheart?”
“I’m sorry you caught us earlier,” Caroline said softly, “but I’m not sorry I did it.”
“You know it’s wrong.”
“Yeah, but it felt so good. I swear, I was using Carl as a substitute dildo but he felt so good I’d love to have him fuck me properly.”
“Was it fair to Carl? I mean, using him to replace a dildo?”
Caroline giggled. “I guess not, but he didn’t complain.”
The women swam in silence for a while, until Judy said, “Be careful, Caroline. I don’t want either of you to get hurt.”
“Does that mean you’ll let us make love?”
“If I’m out at work, how do I stop you?”
“Forbid us.”
“Would you listen?”
“Yes, Mom, I’d listen. And obey, but it would be damned frustrating. It’s so much nicer having a nice warm man attached to the prick that goes into me, rather than just a handle.”
