Joan looked at her mother in amazement. "I had no idea?"
Doris gave her a little hug. "Honey, sex didn't start with you or me. People have been doing it ever since… well, how long is forever?"
Joan giggled and hugged Doris. The heavy cones of their breasts touched and Joan gasped.
"Horny, honey?"
The girl nodded. "My breasts ache something awful and my insides feel all hot and squirmy. I… I want to touch myself, but…"
"But it isn't enough, is it?"
Joan shook her head and sighed. "No, it isn't. I think about Alex and his… jeez, he's so big! And the idea of masturbating just isn't enough, like you said."
"I know." Doris slid one hand between her thighs and, to Joan's amazement, began to play with herself.
The teenager drew away from her mother, shaking her head.
"Don't be so uptight, Joan. I feel the same as you do, only worse. You've never had a man's cock inside you so you can't imagine how wonderful it feels. I have, and… ohhh… ahhh!!" Doris gasped and then screamed softly. Her body relaxed slightly and she slowly lifted her hand away from her crotch, looking at her wet fingers.
Joan gave a soft cry of despair and spread her legs apart. Doris looked at her, and Joan nodded.
"I know it's wrong Mama, but… I… I… I…"
Doris smiled. "Sure, honey." Her hand reached out and she gently stoked her daughter's inner thighs.
Joan gasped at the light touch of her mother's fingers on her body. Her ass wiggled with delight as Doris gently manipulated the outer lips of her pussy and then gently slid the tips of her fingers over her clit.
"Ohhh… Mama! Ohhh, don't stop, Mama… I… I… ahhhh!!" Joan's lithe body twisted against Doris' touch, and the gd's hands clamped over her breasts, lifting and squeezing them almost brutally.
"Oh…" Joan sagged against her mother. She put an arm around Doris and hugged her. "Thank you, Mama."
Doris patted her arm and smiled at her. "Feel better, honey?"
Joan nodded and was about to reply when she heard an unearthly scream.
"What was that?" She looked at Doris.
Doris pursed her lips in a soundless whistle and then shook her head. "That, I think, was Pauline."
"Pauline? But, why did she scream?"
Doris shuddered with lust. "She screamed because her son just shoved all ten inches of his cock inside her – and she wasn't ready for it."
"God!" Joan shivered.
"And if she made that much noise, you can imagine the kind of sounds you'll make when he finally does it to you, honey." Doris patted her thigh. "You don't have to tell me, but are you still a virgin?"
Joan nodded. "Chris Reynolds was a real creep. He was the guy I went out with last week. I thought sure he'd do it to me, but all he wanted to do was play with my tits."
"You've got nice ones," Doris admitted. "But I suspect you'll get your cherry popped sooner than you think."
"But… Alex is so… I… He'd tear me in half!" Joan was near tears. She wanted Alex's cock, but common sense told her she was still too small, the muscles of her cunt too tight to permit anything that big inside her.
Doris got up and waded into the water until it was around her waist.
"Come on, let's paddle around a little bit."
Joan looked back toward the picnic ground. "Can't we go back now?"
Doris shook her head. "Pauline only screamed once. When she screams again, it'll be over. Then we'll give them a couple of minutes to relax. It's only polite, honey. Come on, I'll race you."
Joan got up and splashed in beside her mother. She looked back once more and then began swimming.
Alex had hesitated a long time before touching his mother's pussy. He knew it was wrong, but at the same time it felt so right. His mother's slim body, kneeling in front of him, was trembling and her nipples were big and red.
"Please, Alex. I… I want you to touch me, very much." Pauline quavered.
Alex moved his hand and his fingers brushed the outer lips of her pussy.
"Ohhh…" Pauline shuddered and her oil slick hand gripped the huge thickness of his cock.
"Mom!" Alex gasped at the touch of her hand on his cock.
"Ohh, you're so big, Alex." Pauline smiled at him and then looked at his cock, licking her lips. She began sliding her hand up and down the long, hot shaft, feeling its thickness and trying to imagine how it would feel inside her.
"Ummm, Mom… I… Ohhh…" Alex trembled, his balls on fire.
"Do you want to come?" Pauline cupped his balls gently.
"Yeah!" he gasped, sweat pouring off his face.
Pauline smiled and nodded. "It's all right, dear… I'll suck you until you do, all right?"
"Oh yeah!" Alex put his hand on her head and Pauline opened her mouth, taking the head of his cock into it.
Whatever else she could or couldn't do Pauline knew how to suck cock. She'd started at the age of twelve, and everything she'd learned, she used.
Alex gasped as his mother's tongue curled around the big head of his prick. Her fingers were busy pressing and squeezing his balls gently, but with tremendous effect. He could feel his guts tightening up, ready to explode and send another load of cum out the end of his shaft.
"Mom… I'm gonna come…" Alex warned her.
Pauline didn't answer. She sucked harder and Alex gasped as her fingers pressed his balls back and forth.
There was a warning throb and then Pauline felt a gush of hot cum in her mouth.
"Ohh, wow!" Alex sagged in relief, expecting his mother to stop, but Pauline didn't. Instead she gripped the long shaft with both hands and began pumping furiously, while her warm mouth teased the velvety flesh of his cock head.
"Ahhh!!" Alex thrust his hips up and his cock banged against his mother's throat as another load of cum blasted, out of him.
Pauline coughed and lifted her head, cum dripping out of one corner of her mouth.
"Did you like it?" she asked with a smile.
Dazed, Alex could only nod.
Pauline pushed him back until Alex was lying down, his rapidly softening cock draped over one thigh. She lay down beside him and spread her legs so that her pussy rubbed against his thigh.
"I know you've gotten a work-out, honey. How many times did Joan make you come?"
"Twice," Alex grinned. "She chickened out the second time. She said she was afraid she'd choke on my cum."
Pauline laughed gently. "Joan has a lot to learn, but we'll teach her. Right now I expect you'd like to rest."
Alex nodded. He was exhausted. The head of his cock was sore and he felt as though he couldn't get another hard-on no matter what.
Suddenly he blinked and sat up. "What did you say about Joan?"
Pauline smiled up at him. "I said we'd teach her, meaning Doris and I. It will take a couple of weeks, but by the time we're done, she'll be ready for you."
Alex blinked in surprise. This was something completely unexpected, but then this was a day for the unexpected.
Pauline took his hand and put it on her stomach. "Play with me, Alex. I'd like it very much if you would."
Alex slid his hand between her thighs and Pauline whined with pleasure as his fingers parted the lips of her cunt and slipped inside. She lifted her hips and two of his fingers poked into the mouth of her vagina.
"Ohhh, don't use your fingers, sweetheart, use your cock."
"It… it's all soft."
Pauline smiled. Her fingers closed over the end of his prick and she began to play with it gently.
"Alex, I was a virgin when I married your father. But did you know that I'd been fucking since I was thirteen?"
"Huh? Wait a minute, Mom. How can that… I mean when you fuck, you fuck!"
Pauline increased the pressure of her fingers on the tip of his cock and shook her head. "There's more than one hole down there, Alex."
"In… in your ass? Jeez!"
Pauline nodded. "The very first time was when I was just thirteen. There was this very nice man who lived next to us. One day I locked myself out and he let me use the telephone to call Grandma to come home and let me in. After I got through calling I turned around and there he was with his prick sticking out of his pants. I knew all about pricks. I'd been sucking your Uncle Paul's for six months. I started to suck on it but he stopped me. He took some vaseline and rubbed it all over my asshole. Then…" Pauline smiled and shook her head.
