Sam steps forward

Sam watched from a few feet away, and couldn't believe what he was seeing. He'd known Danny for a while, but they'd never been in this kind of situation before. Sam began imagining what Katie's mouth would feel like on his own cock, which was pressing against the inside of his pants. Sam's dick was longer than Danny's, but not as thick. If she can take that dick, she'd be amazing on mine.

Sam was torn. He didn't want to interfere with what was obviously a wonderful thing happening for his friend and this -- let's be honest -- incredibly hot slut of a girl he was watching. But he didn't want to miss out on taking part in what might be the greatest sexual adventure he'd ever imagined.

He took a step forward, and immediately smelled what he knew was Katie's pussy. It must be dripping wet, he thought. His dick was hard again. He had pressed up against her ass during the previous series of photos, and he remembered what it was like to hold her breasts in his hands. I could have done that forever.

Danny stood on the step stool above Katie. Katie stood on the floor, her hands and mouth working intensely on Danny's cock. Sam stepped in behind Katie, and pressed his crotch against her ass. He pulled the collar of her shirt back, and offer her shoulders. The shirt hung limply, but stayed on her arms; her hands were holding Danny firmly, so there was no way to release the shirt if she didn't release her grasp on Danny.

Sam pressed his crotch into Katie's skirt-clad ass. He placed his strong hands on her shoulders and neck, offering a mild massage for a few moments. He then brought his right arm around Katie's torso, stroking her breasts, which were still held by the lacy pink bra. Sam had enjoyed these amazing boobs during the overalls pictures, and something about being in a bra this time was even more arousing. He fingered the lace of the bra, traced the lines of the straps, touched the thicker material that held the stitching between the two cups, and then returned his hand to the top of her chest, above where the swell of her breasts began.

Katie never lost stride on Danny's cock, nor did she let go of his legs. Danny continued to thrust into her mouth, and she would release her oral grip on his dick every so often to catch a breath of air. When she did, she leaned her head back, landing on Sam's muscular chest. As she drew in gasps of air, her breasts heaved up and down, and Sam got more physical in response, pressing his hands harder into her flesh, sliding his fingers into the cups of her bra, and squeezing her full breast in his palm, pinching her nipples with his fingertips. As she would put her mouth back on Danny, Sam retreated slightly, and brought his hands back up to her upper chest and neck.

Sam wanted to touch her pussy. The skirt was so tight, though, that it wasn't going to be easy. And he didn't want to disrupt the rhythm of the dance so far. He found the skirt's zipper on the side over Katie's left hip. He zipped it down, which loosened the skirt a little bit. It was enough to pull it upward just a bit, which in turn was enough to pull up some of the bottom of it. With the skirt basically bunched up around Katie's waist now, Sam pressed his crotch against her bare ass, contained only by pink lacy panties, matching the bra.

Sam stroked Katie's thigh, and easily slid his fingers between her bare skin and the fabric of her panties. She was right, her ass makes her ass look tight. Katie had an incredible ass. It was firm, perfect handful size, warm to the touch. Sam ran his hands along the contours of her body, and greedily put his hands inside the pink mesh when he had the chance. He reached his left hand around Katie's waist, and navigated his fingers to the top of her panties, just below the bunched up skirt. He slid a hand forward, down, and straight into the top of her panties. His large hand curved around her, and he felt the wetness of her pussy against his fingertips.

As he touched the top of her pussy and grazed the skin around her clit, Katie wriggled a bit. She had her mouth full, and was now getting doubly stimulated at the other end. Sam attempted to vibe with the rhythm Katie and Danny had going on, and combined it with his attention to her breasts. With Sam's left hand down the front of her panties, his right hand over her shoulder and playing with her tits, Katie's mouth stretched around Danny's dick, the three of them writhed and danced in synchronicity.
