Julie had planned on making dinner for her son that evening but instead they went out for pizza. Despite the hot sex they had enjoyed earlier their conversation while they ate was pretty much as it always was for the mother and her son. They had beer with their pizza and ended up getting a second large pitcher as they talked.
About halfway through the second pitcher Josh said that he was curious and asked his mom "so how did things even come about today?"
Julie's son commented on how totally embarrassed he was when she walked in on him masturbating. Before he could even comprehend the shock from that she was on her knees licking his cock.
Julie told him the entire story, from having fantasies after seeing him masturbate when he was eighteen all the way up to her suspicions of him masturbating with her panties on his last visit to her house. Josh looked a little embarrassed when she mentioned that and said "yea, I have to admit that I've always liked to masturbate with your panties."
Even though Julie had set her son up for the events that happened earlier that day she didn't confess to that. She only told him that when she saw him masturbating and again saw how big and sexy his cock was, she couldn't resist fulfilling her long time fantasy. Josh replied "I've always known that sons will fantasize about their moms but I guess I never realized it might go the other way too."
After they finished the beer and got in the car to head back to his mom's house Josh just sat there for a moment. Julie asked "is there something wrong?"
Josh looked at his mom with his mischievous smile then said "you know slut, I'm feeling kind of horny again, and I don't want to wait until we get home. I need you to suck my cock while we're sitting here in the parking lot."
Julie thought her son may be testing her to see if she really was going to be his slut whenever he wanted. That was okay with her as she found the idea of having to pleasure her son in a public place to be very exciting. As Josh unzipped his jeans he told his mom to take her pants down too. He said "I want to be able to see your big sexy butt while you're sucking my cock."
Julie felt the excitement building in her again as she slid her jeans and panties down. She leaned over the console then took her son's cock out of his pants and began licking the head. It took very little time before she had Josh fully erect.
Just before Julie took his ten inch penis into her mouth she said "I feel so slutty doing this. I'm actually hoping someone walks by and sees me with your big cock in my mouth."
Julie hadn't sucked a guy off in a car in a long time and she was loving the naughty feeling of knowing she may get caught while giving her son a blow job. The parking lot was well lit and Julie knew she could easily be seen inside their car. As she sucked and stroked her son she kept making comments about how much she loved his big sexy cock.
Josh was loving it too as he leaned back and let his mom's mouth pleasure his cock. After about ten minutes he said to his mom "it looks like you're about to get your wish slut. There's some guys heading this way."
Josh told his mom "finger your cunt and move your head up and down to make it really obvious that you're sucking my cock."
As Julie bobbed her head up and down on his thick cock she could hear the men's voices as they were approaching the car. Josh told her "now move your head faster slut. There's no doubt they can see you and I want them to know what your doing."
Julie was holding her son's cock at the base while moving her head up and down the full length of his shaft as quickly as she could. As the men walked by the car Julie heard one of them say "someone's having a good time."
She then heard a second voice say "I hope mom likes to swallow."
Josh couldn't control his excitement any longer. He moaned with pleasure and as he pushed his cock deep into his mom's mouth he began filling it with his thick warm semen.
