Martha and Samantha had discovered, when they first began to suck each other's cunt, that cunt sucking was liable to turn into a vicious circle. They both enjoyed doing it as well as having it done, but they both got hot at both ends. Therefore, if Samantha sucked Martha off, Martha's cunt was satisfied, but her tongue was horny. So she sucked Samantha off, in turn, which took care of the dark girl's pussy very well, but made Samantha hungry.
It seemed a never-ending cycle. For the first few nights, they had not figured out how to deal with this and had been forced to take turns eating each other out for hours before they had achieved the proper balance and managed to get both cunts satisfied and both tongues temporarily sated. But then they had solved the problem very logically.
They always ended their cunt sucking sessions with a bout of 69 so that they could both come at the same time and drink cunt juice at the same time, and wind up satisfied at both ends.
When Marlene looked through the spy hole again, the horny girls were just getting linked up for a 69.
She beckoned Carl to join her.
They settled down to enjoy the sights.
Martha got on top first.
She straddled Samantha's face and lowered her head to the girl's raven-haired cunt bush, and they both began to run their tongues up each other's pussies with wild enjoyment.
Since they had both come once already, it was going to last longer this time and they were in no hurry far the climax. Sucking cunt and being sucked was such a joyful situation that they liked to make it last as long as possible and to eventually come at the same moment.
After awhile, they switched positions, and Samantha got on top.
Then they lay on their flanks and gobbled each other's pussy in that position, bucking, pumping and jolting together. Pink tongues vanished up creamy fuck holes as they tongue fucked and eager lips pulled on steaming cunt flesh as they sucked avidly, fairly inhaling each other's pussy.
They varied it a bit by taking turns tonguing each other's assholes and doing some finger fucking. Then they settled down to the long sucking that would lead to a climax, working in perfect unison, knowing each other's body well enough so that they could manage to get the timing just right and come together.
They were both purring like cats at a bowl of cream.
They began to whimper and moan as the sensations built up with delightful slowness. Then they began to melt. Neither horny woman knew which she enjoyed more – drinking succulent cunt juice or spilling the juice out into the other's greedy mouth. The thrill at both ends got all mixed up together.
They shared the same sensations as they shared each other's nectar. The mutual thrill might have been a high-voltage electric current running through their coupled bodies. The hot cunt juice drank at one end might have been the same creamy deluge at the other. Like a two-headed animal, they ground together. Like a smooth, sleek beast with two tails, they fucked with increasing energy as the thrill built to the heights.
Samantha gasped: "I can't hold it, darling – come with me!"
Her words were muffled by Martha's cunt, so that the blonde girl felt them as well as heard them.
"Yes!" Martha cried. "Oh, yes – drink it; drink my cunt juice now!"
They reached the peak together and held it for a lingering moment, both of them vibrating wildly with the thrill. Their fuck juices surged forth. They eagerly gulped the sweet stuff down in this shared feast of lust. Their simultaneous orgasms were not as frantic as the first of the night, but they kept building steadily, higher and higher, prolonged and wonderful. Their suck-crazy lips and cunt-starved tongues worked wildly with total concentration, while each left her cunt to the attention of the other.
They came for a good two minutes.
At last, both drained and satisfied, they stopped thrashing and clung together in that inerted position. They continued to lick each other's cunt, but with less passion, now that it was over, than with affection and tenderness.
Finally, they moved apart and cuddled in each other's arms.
"That was wonderful," Martha purred.
"Ummm – I can never decide which I love more – sucking your cunt or having you suck mine."
"We're lucky to have it both ways."
"All ways, really – with our husbands for later."
"But not tonight," Martha said. "We'll have to do without cock tonight. But I'm already looking forward to sucking you off first thing in the morning, like we used to do at school."
"Ummm… me, too. Yummy."
"I miss those days," Martha said, wistfully. "Of course, it's nice to go home to a horny husband after an afternoon of cunt sucking. This will be the first time since we were married that we ate each other out without having some stiff prick afterwards."
Samantha looked thoughtful and smiled slightly.
"I'd thought of that," she said.
"Still – there's nothing we can do about it. We don't want to pick up any strange men, not being adulterous wives."
"Well, there might be something, at that."
Martha raised her eyebrows, interested.
"What on earth do you mean?" she asked. "I went shopping in town the other day," Samantha said. She had lowered her dark eyes demurely and was blushing, slightly. "I bought something you might like."
"What is it?" Martha asked.
"I was a little shy about mentioning it, in case you might think it was too – well – too much like what real lesbians would do."
"Why, darling – we aren't lesbians," Martha assured her. "There's a big difference between being a cunt sucker and being a dirty dyke."
Samantha nodded and sat up.
She fumbled in her large handbag on the floor beside the bed. When she straightened up again, she had something in her hand. Martha stared at it, not realizing what it was for a moment.
Then her eyes glowed, and she grinned with joy.
Samantha had brought along a huge rubber prick!
Carl and Marlene looked at each other in amazement. Then, both looked back through the spy holes. They could hardly believe it. It was their first day of playing Peeping Tom and Tomasina and, if all days at the Shady Nook were going to be like this, they might well end up fucking each other to death.
Marlene had never had a dildo used on her. She had started fucking and sucking at an early age. With an abundance of real pricks to fucks, she had never even considered using a rubber substitute or doing any cunt sucking, for that matter. But as soon as she saw that mighty rubber cock, she began to long for it. Not having one, she reached for Carl's cock, instead.
Carl's prick was as hard as iron and as hot as could be, his big, fat cock head pulsing. They began to fuck on the floor, both of them throwing themselves into the fucking with vigor.
They wanted to come quickly, so that they could get back to the spy holes and watch the bizarre action in the other room. And they were so horny again that they creamed together after a few strokes.
They turned once more to the spy holes.
They had been right to hurry their own fuck to a conclusion, for that big rubber prick was truly a sight to behold!
