Kelly and Steve had grown completely comfortable with each other. Steve had stopped worrying about Kelly saying anything, and neither was seeking a partner (either of the same or opposite sex) any more.
Kelly did continue to ask friends over for the night, and some stayed for longer than even the weekend. One friend, in particular, seemed to enjoy the times that the three of them made for each other. Leann was definitely spending the most time with them, not that either Kelly or Steve had any objections. Leann was definitely willing to try new things, and both Kelly and Steve loved to see her spurting cums.
One evening, when Leann was visiting, he noted that the girls seemed to be a little secretive. They kept whispering things to each other, sometimes looking at Steve when they did.
"What's the big secret?" he asked them finally.
"Nothing, Daddy, just girl stuff" responded Kelly, and they both smiled at him as they walked away. Steve loved the vision before him--two teenagers, both recently turned 18, and both as sexy as they could be in their birthday suits. Their asses jiggled almost in unison as they walked away from him. He could feel his cock beginning to harden at the sight.
Later, they were all watching a very sexy movie. Not X-rated, just very sexy. Steve and Leann were sitting on either end of the couch, and Kelly was sitting on the floor on an oversized pillow. No one was wearing any clothing, as that seemed to be an unwritten rule in this house. During one of the hotter scenes, Steve looked up and noticed that Leann was starting to play with her own pussy. Steve's cock, which had already begun to get hard from the movie, quickly shot up as Leann continued to rub a finger between her pussy lips. When her pussy began making sloshing sounds, Kelly's attention was attracted to her show.
Steve, without thinking, began slowly stroking his cock with one hand, while watching the show just a couple of feet from him. Leann spread her knees apart, and her soaking wet pussy lips parted, revealing swollen inner lips and copious amounts of pussy juice already. Kelly laid on her back, and began dipping her fingers into her own puss.
An idea suddenly occurred to Steve. He swung his legs toward Leann, and stuck his foot out to her pussy. Leann took the hint and pulled his foot against her sex. She rubbed his foot against her pussy, and quickly, the sole of his foot was slipping smoothly over her cunt lips. Leann then stuck Steve's big toe in between her lips, and it easily slid into her hole. Though the toe couldn't go very far, Steve was able to move it back and forth like a short, thick cock, and Leann was suddenly moaning to her toe fuck.
"MMMMM, keep it up, Steve. I've never had a toe in my pussy before. I LOVE it!" exclaimed Leann.
Kelly had two of her own fingers buried deep into her pussy as she watched her daddy and girlfriend. She moved them in and out in time with her dad's toe movements, and her fingers were quickly soaked with her juices. Leann's moans prompted groaning from Kelly, and when she looked to Steve's erect cock, and watched him stroking it, she suddenly built toward her orgasm. Her cum ran like a stream from her pussy, and flowed between her ass cheeks as her butt lifted off the carpet.
As she watched her dad's toe explore Leann's pussy, Kelly said "God, Daddy, that looks wonderful! See if you can make her cum."
Leann was watching Kelly, and her own orgasm quickly followed. When Leann panted "I'm cumming!" her breath suddenly caught and her body stiffened. Steve withdrew his toe, allowing her pussy to shoot cum straight toward him. When it landed on his cock and upper legs, Steve's cum shot straight up into the air, landing on his midsection and chest, mixing with Leann's fluids. Though they were both still catching their breath, the girls quickly scrambled to Steve, licking the mixture of male and female cum from his body like they were starving. Kelly concentrated on his chest, while Leann licked his legs and crotch clean, paying special attention to his cock and balls.
"Leann, come up this way." Steve motioned toward himself, then pulled her toward his face until her boobs were suspended over his face. "Now, lean down some". Steve took one nipple into his mouth and sucked on it hard, making it as stiff as possible.
