Part 1 of this story was posted under "Mature". Part 2 picks up with Ron and his mom on the way home from a New Year's Eve party where Ron had fucked his mom's best friend, Pam.
~~~~~~~~~~~~~~~~
"Where did you get off to there at midnight?" his mom asked on their way home. "I couldn't find either you or Pam." Ron offered some excuse that he had been talking with some other people in another room and hoped she didn't push the issue. Fortunately for him she didn't.
Ron returned to school a few days later and shifted back into his normal routine. He thought about his encounter with Pam often, but he had no contact with her over the next two months. His spring break was approaching rapidly and Ron, having turned 21 shortly after Christmas, had been looking forward to a trip somewhere exotic with some of his friends. Things didn't work out and those plans fell through so Ron decided to just head home for spring break. Ultimately he wasn't too disappointed as he hoped to maybe have the opportunity to fuck Pam again.
He arrived home a couple of days early as his finals ended before the end of the week, so it was Wednesday night when he pulled up to his house. He settled in quickly and spent the night talking with his mom and catching up.
The next day his mom told him that she had been planning a surprise party for Pam and that she hoped he would attend. He gladly agreed, although for far different reasons than his mother suspected. The plan was that Nancy had assembled a big group of friends who were going to gather at Pam's house. Sandy would keep Pam out until the designated time and they would all surprise her upon her return. The occasion was Pam's 50th birthday.
The party kicked off just as planned and Pam seemed completely surprised when she arrived. Ron had been carefully waiting for an opportunity to talk with her but hadn't yet been successful. In the meantime he busied himself drinking and talking until he felt someone grasp his upper arm. He turned hoping to see Pam but instead found Sandy.
"Follow me," she said quietly as she led him upstairs and into what appeared to be her bedroom.
Ron didn't know what was going on but he was excited to find himself alone with her in her bedroom. As usual, she looked hot that night and wore a low cut top that perfectly showed off her cleavage.
"What's up?" Ron asked trying his best to sound cool.
"I know what happened on New Year's Eve," she bluntly stated. Ron replied with a puzzled look so she continued. "I went looking for mom and thought she might have gone up to her room to refresh her makeup. I opened the door to her room and saw you fucking her brains out."
Ron's jaw simply dropped open in shock and he truly didn't know what to say. He stared blankly for a moment and started to stutter some sort of excuse or apology, he wasn't sure which, when Sandy interrupted him.
"You don't have to give me an excuse," she said as she moved closer to him, "I know mom is hot for her age and that she has been needing a man. Frankly, I got pretty hot watching you fuck her." She paused slightly and Ron jumped in surprise when he felt the touch of her hand on his crotch. "I thought maybe you'd share some of that with me."
Without waiting for his answer she initiated a deep kiss with him and let her tongue wander all over inside his mouth. Ron immediately returned her kiss and wrapped his arms around her back. His cock immediately started to grow hard as their bodies rubbed together while they continued their wild kiss.
Sandy parted the kiss and sat on the edge of her bed in front of him. "Did she suck your cock?" she asked softly. She easily unhooked his belt and opened up his pants. She smoothly pushed his pants and boxers down his legs. His cock sprang out and pointed directly at her face. Sandy wrapped her lips softly around its tip and spent a few moments just letting her lips glide easily around his sensitive tip. Ron groaned in excitement and then groaned again when she opened her mouth wider and took nearly his entire length inside her mouth.
He watched her closely as she sucked and licked at his cock with wild intensity. She eventually released him from her mouth and let her fingers softly slide up and down his shaft lubricated by her own saliva.
"Tasty," she said playfully, "but I want to feel you fuck me like you fucked her." She reclined back on the bed and Ron quickly pulled his shirt up and over his head and stepped out of his pants. He stood naked before her and watched lustily as she pulled off her top and then unhooked her bra. The tits that he had so often stared at and fantasized about where now exposed to his hungry gaze.
He knelt on the bed next to her as she began to remove her own pants. He took hold of them at her hips and began to slide them down her legs. She shifted to help him and soon he had them off and tossed onto the floor. He paused to look down at her naked body for a moment until she took his shoulder and pulled him down over her.
