As Matthew English lay on his side, he initially spread his legs apart with one leg up in the air, and then allowed that leg to eventually settle back on the ground to satisfy his comfort need. The Laaning sisters scooted into position to implement Erica's preplanned oral sexual activity. As she got on her side Erica took Matt's cock into her mouth and started sucking and slurping on his rod.
Vivian placed herself on the other side of Matt to directly face his butt. Parting his ass cheeks, she nuzzled her nose right unto the crack so that she was comfortably able to lick his rear end aperture. Immediately upon sensing Vivian's tongue lapping against his anal opening, Matt's cock expanded in Erica's mouth to its near maximum size. Although Matt had a premonition of what the sisters were planning on doing, still he was taken by surprise and gasped as he felt the Laaning sisters' tongues lovingly licking on his lower intimate parts.
And in the minds of Erica and Vivian their actions were indeed applied lovingly. Despite being a virgin a mere some twenty hours or so previous, Vivian was inclined to try all things sexually within the shortest time span possible. That desire had been fostered by hearing Erica recount her myriad previous sexual experiences during the time her sister was administrating to her illness. Learning of her sister's sexual exploits it was natural for Vivian to desire to emulate her.
Being an overachiever with an affinity to excel in anything she attempted, Vivian was determined to become the sexiest woman she could possibly be. When in that morning Erica had outlined the plan to endeavor this type of oral sex, Vivian was breathlessly excited. Under Erica's tutelage, Vivian was aware that many females were reluctant to engage in fellatio and especially to ingest male ejaculate. So she could well imagine that most would abhor rear end oral sex; and in particular the kind that Erica had proposed to her earlier. As well she got the impression that Erica as wanton as she was, had not yet herself participated in this kind of sexual activity.
Thus, the idea of engaging in this type of oral sexual action before her more experienced sister excited all of Vivian's passions. This prompted Vivian to unequivocally tongue lick Matt's bottom enthusiastically. She was varying in humming, groaning, gasping and sighing, all the while as she applied her tongue on his ass hole and crack of his ass. And Matt could sense that there was no aversion but a genuine enjoyment on the part of Vivian to do what she was doing. In conjunction with Erica's oral action on his cock Matt was quickly a goner as he splattered shots of cum after cum into Erica's mouth.
Erica had as matter of course anticipated receiving a generous mouth full of Matt's sperm and so she had previously instructed Vivian in the morning as to the proposed procedure thereafter. Accordingly, she tapped Vivian's arm to indicate the commencement of her proposed action. Immediately, Vivian abruptly stopped her play on Matt's ass and rolled over to position her head to a sixty agree angle adjacent to Matt's head. She then opened her mouth wide to receive from Erica the remainder of Matt's cum. Erica had per force swallowed some of Matt's ejaculate and she allowed the remainder to spill into her sister's now gaping mouth. When she could sense the last of Matt's semen escape from her mouth she kissed her sister to ensure that the latter now possessed the remainder of Matt's cum.
Lifting herself up Erica winked and smiled broadly at Matt who had collapsed lying flat on his back. And she said to him, "Matt we are going to play a naughty game called 'musical sperm'. It's played like musical chairs. I have programmed this boombox to play some music with intermittent stoppages. While the music is playing the one who has your cum in mouth is free to swirl it around and enjoy its taste and flavor. When the music stops you are honor bound not to cheat or it will spoil the fun. You must swallow some cum and then pass it on. The one who swallows the last bit of your sperm loses and must pay a penalty. I've already started the game by swapping your cum with Vivian who will pass it unto you and you in turn will pass it to me and so it goes until your cum is all gone."
"What's the penalty?"
"You'll find out in due time and you might not mind losing depending on your predisposition, but again you must play the game fair and square."
"Okie doke!"
With that said Erica reached for the boombox she had brought to the picnic and started it playing. The music was highly romantic and appropriately erotic. As per Erica's suggested course of action Vivian indeed sloshed Matt's expelled sperm in and thoroughly throughout her mouth, enjoying the weird enticing appeal of doing so. Any thought of abhorrence in participating in this type of oral sexual activity was dispelled in her desire to experience as broad a range of sexual adventures as possible. The fact that she had not even contemplated lesbian sex never mind this bizarre oral sex game tended to increase her fiery excitement; she even could sense a minor orgasm coursing throughout her body.
When the music stopped for the first time Vivian dutifully took in a small gulp of the cum in her mouth. Then she raised her head to hover over Matt's mouth. The latter had instinctively opened his mouth anticipating receiving his own seed from Vivian. Subsequently when he recalled the memory of this oral sex game, he was shocked at how readily he had succumbed to Erica's sexual scheme. But at the time of being in company of the naked Laaning sisters fulfilled all his notions of the upmost sexual fantasy he could contemplate. Thus he was not inclined to spoil the enjoyable atmosphere by balking to any suggestions Erica had in mind to explore.
With Vivian separated from Matt by at least twelve inches when she opened her mouth to allow the sperm to cascade in a thick stream entering into Matt's mouth the distance of the arc of the flow produced an alluring spectacle. The sight of it was so provocative to Matt that a tiny amount of fresh semen involuntarily oozed out of his phallus. Ever vigilant Vivian took notice of this phenomenon. With the precedence set by her sister she kissed Matt once she sensed she had emptied the load of cum. However before she resumed her position and as the music started again she swung to Matt's cock and quickly sucked up the errant leaking sperm. Her thinking was: 'it's terrible to waste good tasting cum and besides this extra cum might come in handy in this game'.
In the spirit of the game Matt then did swirl his cum in his mouth. He felt a little weird in doing so but such feeling was overshadowed by the euphoria of realizing that he was participating in an exotic sexual game. That Erica his main girlfriend was such a libertine to concoct such a game increased his appreciation of her. And so the cum swapping game continued until...it was Vivian that swallowed the last bit of cum on the third go around.
Vivian had opened her mouth to show the other two there was no more cum for her to share with the others. Erica had mentioned that there was a penalty to pay but it still might be desired, nevertheless. Apprehensively she asked of Erica, "Well I guess I lost and I have to pay a penalty. But you did say I might enjoy it?"
Erica replied, "Well yes it will depend definitely on your outlook and your passion. I brought along a special spanking paddle."
