Jess finds him and interrogates him

Jack lets out a loud sigh and falls back against the front door. He licks his lips as he heard his mom's car pull out of the drive and he tastes Jess's sweet juices again. He looks down and sees 6 inches of shaft sticking out between his hips and where the shorts started to conceal the head of his cock.

Hell, it was amazing that his mom didn't accidentally full-on grab his shaft. That thought made his cock swell even more and bob in his shorts, threatening to make the teenaged-rod pop completely free. With the taste of his step-mom's pussy still on his tongue, he almost started stroking right there until he remembered his sister at the top of the stairs and his step-mom in the kitchen.

"Hey, Jack," he heard his step-mom say. Fuck, she was right next to him, not in the kitchen!

"Um, hey," Jack replied. His cock wasn't going down.

"Were you watching us?" she asked. She looked down and let loose a quiet, "Mmmmm," in taking in her step-son's rampant cock. "Shh...don't answer," she said and then touched his lips. Jess's fingers were damp. Jack tasted them as they lingered on his lips and it was pussy, but not the same as what he had just tasted. It hit him half of a cock-surging heartbeat later; it was his mom's pussy he was tasting!

"Mmmm, fuck," he moaned involuntarily.

"Mmmm...fuck...." he moaned, his knees almost buckling.

"Yes, that's what your mother was doing to my cunt," Jess says quietly, stroking your cock now. "She was tonguefucking my cunt. Right where you, specifically eat breakfast," she says quietly, still pointing, still stroking. "Were you listening to us downstairs?" she asked, squeezing hard. "Were you listening to me and your mom licking each other's cunts?" she purred, her hand softening on your throbbing rod.

"Mmmm...Jess..." Jack moans. She turns back to look at him and looks into his eyes, taking his cock completely out of his shorts and stroking hit, rubbing his precum all over his shaft and head.

"Jack, how many times do I have to tell you, we're family now, call me Mom," she says and then she...
