20 minutes later they were in Kirk's room. His 11 inch cock felt like a piece of iron sticking straight up from his groin as Krista and Kimberly licked and kissed all over it while fondling his rapidly filling balls. "Aaaahhh God Kim," he groaned as she sucked 2 inches into her mouth. "Feels so good Kim." It was going to be a good summer if this was the way his little sisters were going to treat him.
"Don't let him shoot yet Kim, I want some Jizz too," Krista said as she sucked on his now full balls.
It was already too late as Kirk gasped, "Ooooohhh Kim, you're gonna, you're gonna, oooohhh shit," as the ejaculation he was trying to hold back exploded into Kimberly's mouth when she sucked another inch of his cock into it. Her throat worked as she tried to swallow it all but some leaked out the corners of her mouth dribbling down Kirks cock. Krista's tongue was there to lap up what Kimberly missed.
"Kimberly, I told you to wait," Krista said angry that she had missed her share. Kimberly smiled and opened her mouth; it was full of Kirk's Jizz. "Oh good you saved me some," Krista said as she kissed her twin collecting her share of Kirks Jizz.
"Where did you learn about blow jobs and swallowing Jizz?" Kirk asked looking at the twins.
"From looking at Dads magazines he hides from mom in the garage and hearing kids talk at school," Kimberly said. "Besides I've wanted to taste your Jizz ever since we saw you jacking off over a year ago. You won't have to waste it anymore. We'll suck it out of you everyday if you make us feel good too."
"How do you want me to make you feel good?" Kirk asked.
"Like this," Krista said as she straddled her big brothers head and spread the lips of her 18 year old pussy. "Kiss it and lick it like we did your cock. Kimberly and I do it to each other all the time." Kirk stuck his tongue out and tentatively licked at Krista's pussy lips. "Ooooohhh yes big brother, do it some more." Kirk became bolder and started to stick his tongue up inside Krista's now throbbing pussy. "Oooohhh big brother, you're making me all squishy inside," she said in a little voice as she gushed a little juice squirming on his mouth.
"Get off Krista," Kimberly said. "It's my turn. I want some too."
Krista was squirming all over Kirks mouth. He opened his eyes and thought her nipples were engorged. He reached up with his hands and rubbed them over Krista's hard nipples. Krista's pussy gushed a lot more juice and squeezed harder on his tongue as she gasped, "Oooohhh damn Kirk, that's good."
"Krista don't be a pig, let me have some too," Kimberly said. Kirks cock felt like a piece of iron again as Kimberly danced her fingers over it. Kirk felt something warm and juicy on the tip of his cock and thought it was Kimberly's mouth. The whole head of his cock felt warm and juicy and something was throbbing on it when Kimberly gasped, "Ooohh Kristy, I've got it inside of me. I think big brother is going to be my first fuck," Kimberly had the head of Kirks cock just inside her tight pussy.
Krista scrambled off Kirks mouth as she said, "Oh Kim, what's it feel like?"
Kimberly was slowly rotating her hips on the head of Kirks cock as she gasped, "It feels really, really good Kristy. You get to try it next," Kimberly moaned as she continued to rotate her hips taking Kirks cock in another inch. "Oooohh I'm squeezing him. It's way better than Mom's vibrator."
It was all over for Kirk when he looked down and saw 4 inches of his cock in Kimberly's softly squeezing wet pussy. He realized that he was having his first fuck with his sister. "Oooohh God Kim, I'm gonna cum," he gasped as his Jizz shot out of his balls up his hard cock and into Kimberly.
"Ooooohhh it's all hot and warm," Kimberly moaned as she squirmed on his cock sliding down another 4 inches. "You gotta try this Kristy," Kimberly gasped as Kirks cock slid deeper into Krista's squeezing cunt still shooting Jizz. The head of Kirks cock was rubbing on her cervix when her vaginal muscles squeezed hard and Kimberly screamed as she toppled over onto the bed.
