Jack found his mother lounging with his aunt on the couch that day, when he came in.
"If it isn't my *favorite* hunk!", teased Emily. To her surprise, Jack didn't blush. Instead, without a word, he came over and gave her a big smooch on the lips.
While Rose and Emily were still speechless, Jack sank down to his knees, gently spread Emily's legs, and planted another big kiss on Emily's bare pussy.
In disbelief, Jack's mother was holding her hand in front of her mouth'. Her inner voice was telling her to reprimand Jack. But a louder voice was admiring his confidence.
"Hey! How come she gets some and Mommy doesn't?" Rose protested with a wide grin.
Jack smirked and also pressed his mother's legs apart, pulled her panties to the side and gave her a drawn out french kiss on her pale meaty pussy lips. Rose was looking between her legs, watching her lips and Jack's squashed together.
A little out of breath Jack got back up again. Feeling good about himself and grinning from ear to ear, he asked, "How was that, Mom?"
"That's my boy!" exclaimed Rose. "That was great honey! Thank you!"
Now some wheels began to turn in Rose's mind. "Emily, you're not wearing panties?" Then turning to Jack, "And you! You knew that?"
Giving Rose a shy look, Jack scratched the back of his head, "Remember when Aunt Emily got me off with her mouth last time? That day, when she uncrossed her legs, I noticed she wasn't wearing anything underneath her dress."
"Attentive, attentive, young man!" Emily was impressed.
"Don't you soil my precious couch with your wet pussy over there!" Rose warned Emily, only half jokingly.
