"I might!"
"Let's have a look then," said Jim.
Isobel stood up, slapped sand from her shorts and delivered an ungainly curtsy.
"Show us what you've got, Isobel," commanded Jim.
Isobel lifted her top up and flashed her tits very quickly, giving them a glimpse of breast and sweaty stomach.
"Same as yesterday," said Jim to Mary.
"Did you like them?" asked Mary
"I did yesterday, but I like big ones too." He stroked the front of her bathing suit.
"Mine aren't big. Don't be rude."
"Well they're bigger than mine, and bigger than Isobel's," laughed Jim.
Isobel put her thumbs in the waistband of her shorts and started to wriggle them down.
"If you liked that, then I have something else to show you," she said.
But Mary wasn't looking. She was leaning towards Jim.
"Do you want to peek?"
Mary's fingers were daintily holding the zipper tab on the front of her blue one-piece suit.
"Guys!" expostulated Isobel. "I'm waiting."
Mary pulled her zipper down, exposing cleavage, a dark deep cleft between her tits. Jim reached over and pulled the fabric aside exposing a large breast with a diagonal tan line. Below the tan line the skin was creamy white accentuating the rich color of the nipple. Jim reached for the irresistible little nub of brown flesh. Before he could get his fingers on it a shadow fell on him. Isobel was stamping in the water by his legs.
"For fuck's sake! Stop messing with me! What's the matter with you two? I was waiting for you to watch."
Isobel had dropped her shorts and the thick wedge of hair at the base of her little round belly was inches from his nose. Even in the salty sea air he could smell her musky smell and feel the heat radiating from her. Not for the first time Jim was bemused by the sudden embarrassment of riches -- his wife's bared breast on the one hand and Isobel's pungent charms on the other.
"Now what are you going to do, Jimmy?" asked Mary. "I bet you don't know what to do, do you?"
Mary was laughing at him. Jim hesitated, and in that moment she threw herself on him. He found himself on the receiving end of a full body press as Mary squirmed herself over him and mashed her breast into his face. In moments he had found her nipple and he sucked it, and as much surrounding breast as he could, into his mouth. At the same time he felt hands grabbing the waist band of his shorts. They were pulled roughly off his pinned body, snagging momentarily on his heel.
A wet sandy hand grabbed his penis and tugged at the soft tissue. He felt it being flapped backwards and forwards.
He heard Isobel's voice. "Look at the poor little thing! Oh, God, I hope it's not broken."
"Give it some time," laughed Mary. "I think we may have overworked it last night."
"Well, I'll see if I can fix it."
Jim loved being smothered by Mary's copious tit, but was in danger of suffocating in it. On the other hand a lack of air didn't seem to be preventing his cock from inflating in response to Isobel's grasp. Maybe the congestion in his head and the asphyxial ringing in his ears were having a positive effect on his blood pressure. He had heard of people that got off on asphyxiation, but some of them died in the attempt, and he didn't want it to happen to him. He heaved Mary off him and surveyed the scene.
Isobel was holding the base of his cock and swinging it round in circles. It wasn't quite hard and it reminded Jim of a wilted stick of celery as she flailed it around. He wished Isobel would treat it with more respect, but he couldn't fault her single-minded absorption with it.
Mary was getting to her feet and had already pulled the blue suit off her shoulders. She wriggled her bottom and worked the suit down over her thighs. She kicked the crumpled bathing suit up the beach and came back and stood over Jim.
"Jim, this is for you. You can stop watching Isobel for a minute."
She knelt over his face. The sun was blotted out by the pale bulge of Mary's belly and the smooth turn of her thighs. She lowered her crotch onto his face. A little shower of sand cascaded onto his lips to be followed by her pink crevice and its fleshy lips. Mary's warm pussy descended on him, gritty with grains of sand, and he licked at her with a will. She ground her salty cleft into his mouth and he tasted her familiar sweet sap on his tongue. He played with the hood over her clitoris and occasionally allowed his tongue to stray into the maw of her cunt. Right now the only thing he could see was the tuft of hair that his nose was buried in, a nice stretch of white belly, the underside of two large breasts and a stretch of sky.
Things were happening out of his sight too. The hand on his cock had stopped waving it around and was now pumping leisurely at it, a not entirely comfortable feeling as Isobel had trapped some sand in her fist. She was stimulating him and excoriating his skin at the same time. Pain and pleasure. But soon the pumping stopped and a warm wet mouth engulfed the head and slid down the shaft. He felt Isobel's mouth vacuum the sand off him. She spat a couple of times and then resumed the task of sucking blood into his growing organ. She had soon transformed it from a stick of wilting celery into something more like an angry carrot. He heard her say "That's better. That's what I want."
She held him at the root and climbed on to him, guiding his stiffened cock into her pussy. Jim was surprised at how easily he slipped into her and was also taken aback by the fierce heat that surrounded his penis. He also couldn't believe she was so heavy, but it didn't matter. After all he now had two women pinning him to the beach and they were so strategically placed, one on his hips and one on his head, that he couldn't think of moving anyway. Neither did he want to. While Mary ground into his face, Isobel started riding him at a slow canter. That was an interesting sensation because despite the slickness of her passage, the occasional grain of sand would scrape against his cock skin as she slid up and down. But pretty soon she was so wet that any remaining traces of the beach were flushed out and the ride became deliciously smooth.
As Isobel got into her rhythm, Mary was working her now soaking gash over his face. Her secretions leaked into his mouth, so that every so often he had to swallow. Mary tasted as good as ever, and though it was sometimes hard to breathe, Jim was enjoying the simple pleasure of eating out his wife while an invisible woman rode his cock. Only she wasn't entirely invisible. Isobel's hands had found their way round to Mary's breasts, and she clutched them to steady herself as she slid up and down his penis.
Jim, prostrate beneath his two companions, watched Isobel's small hands knead Mary's breasts and then begin to squeeze and pinch her nipples.
He didn't think Mary would last long. She seemed to have a direct connection between her nipples and her clitoris, as if the stimulation of them released some sort of electrical charge, which set her clitoris tingling and soon pushed her over the brink.
"Oooof," said Mary as the convulsions began to overtake her. Jim watched Mary's hands grab Isobel's and squash them even more tightly to her breasts. Her stomach heaved and rippled. She pressed herself ever harder into Jim's mouth. He licked and sucked and swallowed and slathered his tongue up and down her, at least as far as he could move, which wasn't very far.
Mary's whole body shook and she cried, "No, No! Oh, God, Stop!"
Orgasms ripped through her, but still she pressed down on his face.
"Stop, stop!"
Jim couldn't, of course. She was the only one who could stop it and in the end she toppled off him onto the sand.
"Too much! That was too much."
She left him to Isobel. Isobel put her hands on his shoulders and peered into his soaked face as she bounced up and down on his engorged prick.
"Come on, Jim. Let's get going."
Jim, catching his breath after his release from Mary's saturating siege, couldn't answer beyond a simple groan. Isobel flew up and down his shaft. To Jim it was a wonder that she managed to keep him inside her, judging her strokes to a fraction of an inch, stopping her upstroke within a hair's breadth of him falling out and then plummeting down again to crash her clitoris against his pubic bone. He felt his buttocks being driven deeper into the sand.
Mary, her body now dredged with sand, rolled over on her stomach and peered into his sweaty face. She pressed her lips to his and kissed him deeply. Even while her tongue explored his mouth and he tasted the sweetness of her saliva he could feel the eruption swelling in him. Jim passed the point of no return. He moaned into her mouth as the ejaculation began to roar in his pipes. Isobel slowed her ride up and down his cock. Her insides clenched its spurting head, sucking hungrily at him. While he sprayed sperm deep inside Isobel, his wife clamped her mouth over his in a fierce and aggressive expression of possession.
Mary pulled her mouth away.
"Next time," she said to Isobel, "he's all mine!"
Isobel didn't answer but climbed shakily off Jim's still stiff cock. She left a snail trail of cum on his belly which Mary wiped away with a sandy hand.
Isobel brought the picnic from the boat. They spread beach towels next to each other and laid the food out. Jim was relaxed -- he enjoyed the wine, and the feeling of Mary rubbing sunscreen into his sun-scorched skin. He couldn't help noticing that Mary was very possessive, in a way that she hadn't been last night or even yesterday. She fed him morsels of food as if he was a chick in her nest. Isobel sat by them, but just far enough away that her position seemed to acknowledge Mary's rights to him.
That was all right with Jim. The sun was beginning to get to him anyway, and the sex already had. His eyelids became heavy and began to droop and a post-fuck nap overtook him.
He was awakened by the sound of an anchor chain running out. Mary and Isobel were sitting at the water's edge watching another boat anchoring in the bay. It was a ketch with a green hull and wooden masts and a deckhouse on which the varnished bright work glimmered in the sun.
"Bummer," said Jim. "I thought we had the place to ourselves."
Mary said "Why are you so grumpy? There's plenty of room in the bay. Anyway I thought you'd be glad of some company. I expect you're pretty fed up with having just us two women to ..."
"...keep him out of mischief," interrupted Isobel.
