"Mom?" Nick heard the TV in the basement. He descended the stairs and found his dad watching the game. Nick kept his lower half behind the door frame so the tent in his pants would be out of view. "Hi Dad. Where's Mom?"
"I think she's upstairs taking a shower." Fred glanced at his son. "She was bummed you missed dinner. Your mother works hard around here, the least you can do is show up."
"Um... sorry..."
"You were with that girl, Maggie, right?" Fred nodded and turned his attention back to the game. "I remember being your age. My old man yelled at me more than once for turning up late." He turned the volume up on the TV. "I think your mom left dinner for you on the counter."
"Thanks. I'll just go to my room," Nick mumbled and left. Once upstairs, he went straight to his parents' room. He let himself in, crossed over to their bathroom and listened. He could hear the shower going. Would she be happy if he surprised her? It seemed less than likely with his dad home, but his hormones got the better of him, and he tried the handle. It was locked. "Mom?" Nick knocked. "Can I come in?"
"No... Nicky." Kate sounded a little short of breath.
Nick thought about the right way to phrase things. "My girlfriend dropped me off. We made out, but she left me with the biggest... erection." He tried to say the words loud enough for her to hear through a door with a running shower. He was glad his dad was all the way down in the basement. "I thought I could just play video games and forget about it. But I'm too worked up. And video games can't compete with you." There was a long pause. Nick waited. "Mom?"
The door opened a crack. "What's your father doing right now?"
"He's watching the game. Start of the third quarter." Nick could see part of her large, hanging breast. Lower, he caught a glimpse of her shapely leg through the crack in the door. She was naked and dripping on the floor.
"Oh, gosh." Kate peered at the tent in her son's pants. "I'm going to regret this. Come in." She opened the door wider and quickly closed it behind him. She made sure it was locked. "Your girlfriend left you high and dry?"
"Yeah, Mom." Nick quickly undressed. He stared at her teardrop boobs. "And I missed dinner."
Kate thought she knew what he really meant "I don't suppose your girlfriend fed you. Are you hungry?" She pushed out her chest to offer him a nipple and took hold of his penis with her hand. "Oh... my... gosshhhhhh." She sighed when his lips locked on her breast. "I'll take good care of you, Nicky. Even... when... your girlfriend... can't." She thought about turning the shower off. Normally, she wouldn't waste the water, but she figured it would help hide what they were doing in case her husband wandered upstairs. Her husband! This wasn't worth the risk. Why couldn't she just wait until Fred went to sleep? "I have to take care of this... now, don't I?" Her hand worked hard on his penis as he drank. "You're so pent up... it can't wait, right?"
"Mmmpppphhhhhhh." Nick nodded into her breast. He thrust his hips, sliding his dick in her hand. His cock pressed against her belly repeatedly.
"Let's be quick... quick..." She could feel his precum smearing on her skin. He smacked his thing into her again and again. She knew she should simply put him in her mouth and finish the job. Instead, she pushed him off her breast and turned around. "You have to promise... you won't put it in. Only my thighs, got it?" She put his penis between her legs and pressed them together. "Promise... me... you won't put it... anywhere... else." He had gotten her so worked up, she wasn't thinking straight.
"I... promise." Nick stared at the delicate curve of her back where it turned into the rolling expanse of her ass. He stood stock still.
"Move your hips like you were doing before." Kate put her hands up on the wall and waited. "Go on, sweetie. Talk to me about... how you'll cover me. It's okay, I'll rinse off in the shower. I want you to spray my back. I want to feel... ugh... the heat... of it." A shiver ran down her spine when he started pumping his thing between her thighs, rubbing against the bottom of her lips. "Talk to me... sweetie. Tell... me."
"My girlfriend... didn't empty them, Mom." Nick was growing to love her fantasies. "So... I'm going to... have to cover you in cum. It'll... be dripping off you. I'll mark you with it. Dad will wonder why you smell -"
"Don't talk about your... uh... uh... father," she hissed. "Not while he's... downstairs."
He could tell from her tone that he'd almost ruined the moment. "Sorry... Mom. It's just that my girlfriend... drove me crazy... and left me high and dry."
"Yeeessssssssss." He hips bucked. Kate shut her eyes tight and orgasmed. Her mind left her for a few moments. When it returned, she could tell that she'd squirted all over him. He was incredibly slick.
"Can I pretend... that I'm inside you?" Nick took hold of her hips. His only point of comparison was his sister. His mom's hips were wider and offered more to hold onto.
"No..." Kate shook her head and looked over her shoulder. The intensity in his face startled her. "Well... okay. But only pretend."
"Your pussy is so... tight... Mom." Their skin slapped together loudly. "When my girlfriend... won't finish me... only your pussy... will do."
"Don't use... ugh... ugh... the p-word... Nicky." She was going to climax again just from him rubbing on her lips. How was that even possible?
"Best... pussy... Mom." Nick had pushed her successfully on accepting the word "cum." He might get away with saying "pussy." Deep inside, he yearned to stop playing pretend and stick his dick inside her. But he remembered how badly that had gone in the loops. "Gonna... cum... Mom."
"Cum on me... oh... gosh... yesssssss." She felt his penis leave the protection of her thighs, and she knew he was finishing himself with his hands. She was so close herself. She wiggled her butt and reached between her legs. Rubbing her clit, she exploded a second after she felt the first hot splash hit her back. "Eeeeeeiiiiiiiiiiii." Her stifled scream sounded very loud in the small, steamy bathroom.
"Aaaaaahhhhhhhhhhhh." Nick unloaded on his mother's backside. When he was finished, she was covered from her hair down to her butt. There was even cum on the wall. He slapped his dick on her wiggling ass as he finished, listening to her mewl. "Wow... Mom. That was... amazing."
"Yeah... honey... it was." Kate leaned against the wall and panted. Sweat dripped down her boobs. What had they just done? "Okay... okay... I'll clean up in here." The feeling of his heavy penis resting on her butt cheek sent a shiver down her spine. "You have to go..." She tried to clear her head. The door handle rattled as Nick unlocked it. "Get dressed first!" She turned and helped him pick up his clothes. "If your father catches us..."
"Yeah... sorry..." Nick was normally all smiles after hanging out with his mom. But this time they both wore serious expressions. He dressed quickly.
"This was my fault, Nicky." Kate took a towel and mopped up the puddle on the tile underneath where she had been standing. "I got carried away. I shouldn't have invited you in."
Nick poked his head out of the door. The coast was clear. He looked back at her as she cleaned the floor. "I'm sorry, Mom. You're just... too perfect. It was my fault, too."
The barest hint of a smile flickered on her face. "Just go! We'll talk later." She watched him disappear out the door. She listened for her husband's angry voice, but of course he was still engrossed in the game. There was only silence. They had dodged a bullet. She sighed, locked the door, and went about cleaning in earnest.

Kate wore her new lingerie for Fred that night. She wasn't sure if it was guilt, or if Nick had simply wound her up so tight that she craved dirty sex. Whatever the cause, she needed intimate time with her husband. As Fred pulled on his pajamas, Kate sashayed into the room, making sure to sway her hips and jiggle her heavy boobs.
