Two little sisters explore their big brother.

I watched with wide eyes as Jessie gasped from Tony's touch. Her little feet began to inch apart on the floor, giving him better access as his thumb continued to gently run over her clit. I crawled up on my knees in the bath to lean over the side, getting water all over the floor as I watched.

"See?" he said, leaning down to give her a little kiss on the belly button, then lower and lower til he was kissing just above Jessie's slit. She nodded slowly, her eyes shut tightly. She was beginning to make small noises in her throat, like a kitten mewing, and she was breathing very hard.

Because of the cold, both her and my nipples were hard and as I sat in the warm water my hips began to wiggle back and forth as I started to tingle between my legs.

Abruptly as Callie was making her mewing noises and before he got to kissing her privates, Tony picked her up and gently put her in the bath, immediately getting the soap and he was about to pour it on his hand when the two of us cried out in protest.

"Hey! You gotta take a bath with us!" I said, crossing my arms over my chest, just below my hard nipples. Jessie mirrored my gesture, though she was still panting from Tony's touches a few seconds earlier.

Tony sighed deeply, but he was smiling as he stood to climb into the big tub with us. Still though, to make room, Jessie stood up and over me as he got in next to us.

Though Jessie and I had been in a bath together numerous times, we'd really never paid attention to each other's pussies before. Now that Tony had been playing with Jessie like that, I was curious. I reached my hands up and ran my fingers over her slit from the top to the bottom, and noticed that she was wet but not from the bath. She was slippery and warm and she started to mew again as I rub her pussy clumsily, using my whole hands to put pressure all over the slit.

This went on for a few minutes as Tony watched, his hand on his cock as he stroked himself, watching us.
