My mother's favorite cousin was Serena. When they were young, they lived on the same block and were best friends. They did everything together. They even lost their cherries on the same double date in the old drive-in movies.
But after high school, their lives took different directions. Mom married an intellectual whose vocation was office work, but other than performing his connubial duties, he spent countless hours at the bar, telling war stories. (Yes, at least he served his country when needed - I'll give him that.)
Serena married an adventurer, fresh out of the Marines, but he didn't have time for taverns, nor did he care to rehash the war. What he did care for was oil wildcatting. He had just enough time to give Serena two children before he was killed at a well explosion. Mom was so devastated for Serena, who never remarried - no one could measure up to her Greg.
When Serena moved back to our state (from Oklahoma to New York), she settled close enough to visit often with her mother at a private lake where our mom often brought us to see Aunt Alma (Serena's mother).
As a result, we kids were a constant summer foursome, all within two years of each other in age. Serena's children were Terrence (Terry) and Lisa, Lisa being two years younger than her brother.
I (Pete) was Terry's age, but my sister Katherine (Kitty) was only one year younger than Terry and me.
As we grew toward puberty, we made physical discoveries among ourselves (playing doctor), and it was before any of us had been given the "speech". Somehow, perhaps because of the guilty feelings this engendered, we knew enough to keep what we did a secret among ourselves.
Terry and Lisa, without authoritarian influence from their dad, did what they pleased at home, and that included taking the game of doctor to new levels! They had actually gone "all the way" and they loved it. Terry couldn't wait to brag about it to me while Lisa told Kitty the woman's side of the same deal.
Kitty grimaced with the revelation about incest, almost feeling the hellfire we were always promised if we ever did anything like that!
But Lisa was very, very persuasive, such that she convinced Kitty to get rid of her own cherry via cucumber, and save the occasion of the real thing for better pleasure.
Meanwhile, just the description of what went on between Terry and his sister gave me a boner! I wanted desperately to bone Kitty now!
Then Terry came up with an observation: since we were second cousins, it's not considered incest to copulate - he could do Kitty and I could do Lisa! (I had no idea if he was BS'ing me or not, but I wanted to believe it, so I did!)
It took the better part of the summer of our fourteenth year before Terry finally seduced Kitty. By then, Lisa and I had done the deed several times. But I was still not satisfied: Terry screwed both girls!
Two years later, mom shot dad during one of his drunken rages. She was advised to plead to involuntary manslaughter, but the judge made her do a minimum of a year and a day!
In order for us not to be tossed into the "system", Serena agreed to take us in while mom served her time. (She'd be out in six months, in October.)
Now the four of us were together constantly, and with no distance to separate us, we began humping like minks: Terry and Kitty, me and Lisa.
At fourteen, Lisa was really coming into her own, sporting a pair of pouting lips, lucious hips, and rock hard nips! Kitty had already developed into such a hottie that Terry had to be careful not to impregnate her. (Lisa was on the pill.)
It often got messy because Terry had seen too many porn movies and he'd pull out and unload onto Kitty's stomach! I much preferred my way, and so did Lisa. That's why she was on the pill - she loved feeling the hot seed spreading insde her, but also, she was still doing her brother.
One hot August night, after showering for bed, and while the girls were now taking their showers, Terry suggested we switch beds!
"They'll know!" I snapped in a whisper; but Terry was already unscrewing the ceiling light bulb. He was doing this for me, so I went along.
When Kitty flicked the lightswitch three times and got nothing, Terry and I let out two of those horror movie laughs, "mooooohhhhaaaaaaaaaaa", which helped disguise our voices.
Lisa cuddled up to her brother and called him "Pete". Then they got right into it.
Meanwhile, I needed to perform orally on Kitty right away so I would have an excuse not to speak, and I shucked that towel she was still wrapped inside, and I got her under the covers. After all, a body just out of the shower feels cold until some heat is trapped. It was my body heat which made her feel comfy.
I worked her as I had seen Terry do, nibbling her nipples, then kissing my way down to her sparse fur, all the while keeping the covers over us.
When the moment of truth occurred, Kitty was as reliable as ever, reminding me to pull out. (Why she didn't go on the pill, I'll never know.)
Well, my spit-lubed tip pried its way into the vestibule of my sister's honeypot, my anticipation building as I sank slowly inside her. When we were pube to pube, I let out a sigh and withdrew half way, then slowly sank back inside again.
It never dawned on me that Kitty was tighter than Lisa (since she was a year older, I expected the contrary). The result was that I wouldn't be able to last as long with such firecracker friction!
I knew I would have to pull out in a matter of seconds!
But just as I began to withdraw (we hadn't even begun the rapid humping yet), Kitty locked her legs around my ass, pulling me back deeply.
I lost all resolve and started thrusting wildly, fusing our pubes with each pump, drilling my sister like nothing I ever did with Lisa!
Terry had more staying power than me. Kitty was probably counting on that.
When she the felt the hot wet jets of my seed blasting inside her depths, Kitty screamed, "No! You didn't! Take it out, NOW!"
I took it out - way too late - and continued to spew onto the bed, as Kitty raced to the bathroom.
I panicked and said to Terry, "Quick, we have to switch back before Kitty returns!" (I didn't know or care whether Lisa was privy to this or not, at that point.)
Terry laughingly said, "No way José! You weren't supposed to get her pregnant!"
I said, "I'm fucked!"
Lisa said, "YOU'RE fucked? How do think Kitty's going to feel?"
Naked and dripping cum from my detumescing weapon, I raced to the bathroom to see Kitty.
When I got there, she was pissed ... at TERRY! She said, "That fucking prick didn't pull out, Pete. He shot me full of sperm. My period was two weeks ago. Shit, I knew I shouldn't have done anything this week!"
I said, "I'll be right back!"
I went back to my bed, threw on a pair of shorts, and raced to the kitchen, looking for ... anything.
I came back with the (yellow) dispenser of ... mustard!
I ran the hot water tap while I removed the top to see how much mustard remained in the container. (Perfect! There was very little left, maybe not even enough.)
I ran some hot water into the mustard container, then violently shook it all up, then filled it with more hot water and again violently shook it up.
I told Kitty that this shit is prepared with vinegar, and it already has acid. Since it's edible, it shouldn't be harmful to use as an emergency douche, and she needed to be supine. So I ran hot water into the tub just to remove the cold from the bottom of the tub (maybe an inch or so of water).
Kitty was desperate like me - she was willing to try anything at this point, no matter how fucked up it turned out to be!
The dispenser has one of those tiny, pointed spouts, and it allowed me to squeeze out hot jets of makeshift douche, but it would never get deep enough to be of any use!
I told Kitty I had to pry her open with a finger or two for the stuff to have any chance of working. She let me.
As she announced that it seemed to be working and that she could feel the juice inside her, I told her that I would have to repeat with just water several times to remove all traces of mustard.
As I did this, Kitty tearfully confessed to me that she should have let me have her a long time ago, because I was so much more responsible than Terry.
I died a thousand deaths!
But I figured the best time for confession was right then because Kitty had no access to any weapons.
I told her, "Before you go to sleep, you must know that Terry and I switched beds tonight. It is MY sperm that you captured. I'm sorry baby, but you were just too sexy for me - I couldn't hold off."
"And Terry and Lisa are in on it too?" asked kitty.
"Terry is - I don't know about Lisa, except she knows NOW!" I said.
Expecting a tirade or flailing hands, I was shocked when Kitty softened her tone, asking, "Do you really think this will work?"
Truthfully, I told her, "I doubt it sis. But sooner or later this was bound to happen with Terry, too. In a way, I'm glad it will be MY kid!"
We cleaned up and the clock began its two week countdown.
Kitty had words for Terry and Lisa (and me), essentially reminding us that what we did was remove her choice - certainly a form of rape, by deception.
Lisa reminded Kitty, "I told you from the get-go that guys will always lose control, sooner or later, and that was why I'm on the pill!"
Kitty acknowledged that.
Fifteen days later, Kitty and I were now a thing (and in the shower together) when she smiled and suddenly showed me the mustard dispenser! She ordered me to bend over, which I did.
I said, "I haven't had an enema in ten years."
Kitty said (as she inserted the squeeze spout), "You've never had an ice water enema!"
Then as she won the struggle, she squeezed out a blast of Antarctic H2O deep into my bowel. I almost had a heart attack on the spot, but also somehow, my bone was hard and threatening to cum into my own face!
"Now we're even, period." Kitty announced.
"Period?" I asked, unsure if the irony was intentional.
"Yes! Period!" Kitty confirmed.
[Readers: I don't recommend the mustard douche ... or the ice water enema!]
