Lisa wiggled her hips. "I think it would be great."
"If you're willing, so am I."
"I knew you would be." She grinned, watching him pull on his pants and a T-shirt.
They left the house. The evening was warm, and her thin wrap-around dress clung to her shapely body, so thin that it could almost be seen through.
"This makes me feel so wicked!" She giggled.
"Me, too," he replied.
They walked a few blocks until they came to the post office. It was closed, but the room where the mail boxes were located was open and well lit.
They stood and looked inside a moment, then Lisa tugged at his hand. "Let's go in there."
"But we can be seen if anybody passes."
"Isn't that the idea?"
"Yeah!"
Lisa skipped up the steps and entered the well lit room. One wall was filled with post office boxes, with a long table near the windows.
Feeling excited, Lisa untied her belt, and with her wrap-around dress flying she skipped from one end of the large room to the other, her cunt end tits flashing.
Johnny watched her, his cock growing in his pants.
"Take your cock out!" She laughed, holding her dress about her waist and waggling her naked ass at the windows. "Let's be nasty, baby."
Johnny pulled his cock from his pants, watching her while she danced up and down the room, wiggling her ass, spreading her legs and jutting her cunt toward the windows.
They laughed like naughty kids, very excited with what they were doing.
Lisa leaned against the row of mail boxes, spreading her legs wide. She rubbed at her hairy cunt, spreading it open as she faced the windows. Johnny stood near her, watching, as he slowly pumped his cock. Lisa began to pant with heat as she watched him. Being so open thrilled her more than she had expected, and her cunt was on fire, hot juices running along her inner thighs.
"Ooooh, this makes me so fucking hot, Johnny!" she moaned. "My cunt is so hot, I could fuck an army!"
She pushed away from the wall, her hand curled between her thighs. She eyed her son's cock hungrily. "Johnny, fuck me now! Fuck mother here and now!"
Johnny moved up behind her, just tall enough to fit his cock to her cunt without bending his knees. When she felt his cock at her pussy, Lisa began to moan with eagerness, grinding back against him as he pushed his cock into her cunt.
"Ooooo, baby! Fuck that hot ass!" she whimpered, twisting her ass for him.
Johnny rammed in and out, watching her ass writhe. "You're wet, Mom."
"So wet, I'd drown you if you sucked my cunt now!"
"I'm not gonna suck your cunt – I'm gonna fuck it!"
"Yes, baby! Fuck mother's hot cunt!"
Lisa thrust her ass hard against him. Being so open sent chills of erotic ecstasy through her. She stared out the window, feeling the increasingly wilder lunges of her son's cock. Her cunt burned and gripped him, her ass twisting. Her tits swayed and she panted from the force of his fuck-lunges. She began wishing someone would come in and see them. She felt so excited that she was sure she would come immediately if anyone stepped through the door.
She began to see images in her spinning mind, images of other people fucking, sucking, spread on the floor of the post office, all eyes staring at her as she took her son's cock hungrily into her cunt.
"Fuck it, fuck it!" she sobbed. "My son is fucking me! My son is fucking my hot cunt! I'm fucking my son and his cock is so hard and my cunt loves it in there so deep!"
Johnny smiled. "Hey, look! I'm fucking my mom! I can make my mom's cunt hotter than anyone! Watch me fuck my mom! Look at her shake her hot ass, look at her hairy cunt, her pretty tits!"
"Look, everyone! My son is fucking me!" Lisa sobbed. "See his hard cock fuck my cunt! Watch us fuck!"
"I'm gonna come in my moms cunt!" Johnny shouted. "I'm gonna come in my mom's hot, juicy cunt, then she's gonna suck my cock!"
"Ooooh, look at us!" Lisa cried. "My son is going to come in my cunt! I'm going to suck his cock off, make him come in my mouth, then fuck him with my ass! Look at us… watch!"
"Mom, I can't hold back!" Johnny wailed.
"Ahhh, squirt it in my pussy!" Lisa sobbed. "Come in mother's hot cunt! Watch my son's cock squirt in my hot, wet writ, everyone!"
She shook her ass frantically, her pussy clutching his cock tightly, her clit swollen. She began to strain. Her face was flushed with an impending orgasm.
"Johnny!" she cried out in a strangled sound.
"Now, Mom!"
He rammed hard and deep, clawing at her shaking hips.
As she felt his body discharging, Lisa cried out loudly, her cunt contracting with a burning, sweet orgasm.
"Ooooh… ohhhhh!"
"Ahhhh, Mom!"
All her muscles seemed to become liquid. She slumped over the table as her son pulled his cock out of her cunt. She breathed deeply, listening to Johnny gasping for air behind her.
"A car's coming, Mom!"
"Who cares," she moaned, not moving.
The car came and passed without slowing.
"Do you think they saw us?" Lisa asked softly.
"I don't know, and I don't care, Mom."
"Mmmm, you and me both," she purred. "Johnny, that was, great, wasn't it?"
