For days after fucking around the fire pit, my mind played the nasty scene over and over. I was especially enamored with Big Jim's monster cock and my bi-sexual nature was stirring strongly even as I went out of my way to stare at the MILF next door, Debbie, and plot our next liaison.
When the phone rang the caller ID said it was Debbie (her special ringtone was "Hot Stuff"), I was hoping for an invitation to explore her wanton depths. But instead, she was telling me she had to leave town for a few days -- something about work -- and while "the girls" (as she referred to her daughters) did not need babysitting, she was hoping I would look in on them from time to time to make sure they were OK.
"They're good girls, most of the time," Debbie said of her babies, Diana, nineteen, and Dakota, seventeen. "But I worry about boys being a bad influence. So just keep an eye out." And then in a whispered, sexy tone: "I'll pay you for your time when I get back. Promise."
Of course, I said yes. They couldn't be much trouble and I completely understood what kind of bad influence boys could be, especially teenage boys who only have one thing on their minds. Been there. Done that.
Maybe I will do that again, I thought as juices stirred in my groin.
The next day I was out on my back deck, basking in the warm sun, wearing a pair of gym shorts and an old sweatshirt with the sleeves removed. I was pleased when "the girls" came out their backdoor and started a game of catch with the frisbee. They ran back and forth, tits bouncing, ass cheeks undulating, long blonde and black hair flowing back and forth in ponytails. They shouted and they giggled, and they were turning me on.
Finally, I stood up and shouted their way: "Diana. Dakota. When you're thirsty, why don't you come over and I'll get you something."
Diana, the older one with the larger chest and dark hair, looked over and smiled. "Or you can come. I mean come over here. Two against one."
My cock surged in my shorts. Was she taunting? Teasing.
I grabbed a bottle of Scotch from the outdoor bar and headed down the stairs and across the yard. The girls’ mom didn't say anything about me being a bad influence.
Once in the neighbors' yard, I could see the teenagers were working up a sweat and their bra-less breasts were poking through their terry halter tops. I guessed that Dakota, was an A-cup, tiny little tits that needed no support. Her legs were toned, and her thighs were muscular, indicative of her time as the catcher on her high school softball team. I leered as I thought of them wrapped around my ass as I pounded the slick tight tunnel between her legs. Diana was bigger, both in the chest department, and taller, closing in on 6 feet. Her sweaty boobs were nearly the size of her mom's 36 Double Cs. As I stopped a few feet from where they were standing on the patio, I took a swig of the Scotch and offered it to "the girls."
"Your mom asked me to look in on you while she's gone," I said with a smile as Diana took the bottle and tugged at her halter top to keep her tits covered. "I told her I thought you were big enough to take care of yourselves, but in her mind, you are still her babies."
After Diana passed the booze to her little sister, she put her hands on her hips and spoke. "Babies old enough to have babies, if you know what I mean. Besides, we don't need any man checking up on us."
"But if a guys want to party," the smaller of the two said, "well, then that's a different story." She rubbed her crotch and looked at her sister, untying her halter and letting her tiny tits air dry.
"Why don't we go inside so nobody sees," I said.
"Oh, you mean unlike the other night when mom and you were fucking and sucking in the middle of the backyard?" Diana said, leading the way through the garage to the kitchen where I had first encountered their mom's lust.
Dakota let me know she seen our little liaison too. "Well, that was quite a show. And that guy, I don't know his name, did he have a monster dick or what?"
"Jim," I said, telling them the man's name who was cavorting with their mom and me. "I've never seen anything like it either. Do you want me to see if he's available? He loves a good party with pretty girls."
"Oh, hell no," Dakota said. "That cock could split me in two. Diana and I like to play with different things, but I could never imagine a baseball-bat-sized dick inside me."
All this talk was making me hornier as we made our way into the living room. In the middle of the room was a large, soft fuzzy area rug. Dakota was already on her back, pulling her shorts off to expose a very hairy pussy. Blonde was her true color, I saw, and by the looks of her labia, she was already getting excited for what was to come. Or cum.
"Hey Tom," Diana said as she snuggled me from behind, rubbing those naked tits against my back. "Have you ever seen two horny sisters make out?"
She got on her knees to join Dakota on the rug. And before I could say a word, the two of them were exchanging French kisses as their chests rubbed together. Their naked asses pushed back and forth, and they moaned. I kicked off my shorts, took my sweatshirt off over my head and found a seat on the sofa. My dick was at full salute and begging for attention.
Diana, clearly the ringleader of this deviant sex club, looked over at me as she slipped a finger or two in her sister’s pussy.
“Hey big boy, while you are checking on us, why don’t you use that lube on the table and play with that poor little prick of yours. It sure looks like it needs attention,” she said.
I took another shot of the Scotch and did as I was told. I poured some cool clear lotion onto the top of my concrete cock and gripped it.
“Oh fuck, girls,” I said as the two teen cuties went back to their lesbian tryst. “You put on a good show that makes a poor old man like me lose my mind.”
My hand slipped easily from the top of my nine inches to the base. I slipped my well-lubed hand onto my smooth ball sac and squeezed my cum laden nuts.
