Traci comes back from the shower

"Well, it looks like you were busy while I was gone," Traci said from the doorway. "I bet Marisa wanted to see what your tongue was like, am I right? She really loves oral."

Marisa and Jessie giggled as Traci walked in. Her hair was damp, and though she was mostly dried off, tiny droplets from her hair snaked down her naked skin.

"I get to be the next lesson for Mike," Jessie said, lust thick in her voice. "I haven't had a go yet." She climbed over my body, scooting up to my head. She held the headboard of the bed as she lowered her pussy to my mouth. "It's only fair," she continued, "that we all get equal treatment." I licked her from taint to clit. Jessie closed her eyes and purred.

I mouthed her pussy lips and then drove my tongue deep in her weeping slit. Jessie moaned, followed by groans from both of her sisters. I couldn't see anything, but I figured they were pleasuring each other, maybe a sixty-nine. I desperately wanted to watch, but Jessie's thighs were in the way.

My step-sister leaned up higher, giving me a better position to reach her cunt and asshole. Now I could see Marisa on top of Traci, licking her pussy and getting the same in return. The sight made me redouble my efforts to get Jessie off. She started squealing at my increased action on her cunt. In another minute, she screamed at the top of her lungs and came hard. Her juices dribbled into my mouth, spicy and sweet. Her whole body shook, and she would have had trouble sitting upright were it not for her tight grip on the headboard. I sucked her clit until she leaned hard on the head of the bed.

Once she had recovered some of her breath, she said, "Oh, Mike. We're going to have a great summer."

The sounds of my other sisters getting each other off followed, and everyone lay on the bed, panting.
