“She’s definitely a free spirit, son,” his father said. “I appreciate you letting your old man get a look or two.”
Dex chuckled. “Well, knowing my girlfriend, she’s probably forced you to do a little more than look. It’s okay though,” Dexter said, patting him on the shoulder, “I know my girl.”
Don laughed easily, and Dexter smiled, enjoying the sight of his dad being happier than he’d seen him in a long, long time.
“Gonna go join her?” Don asked.
“Maybe,” Dex said. He saw the notification light blinking on his phone and checked. There was a voicemail.
“Hey Dexter,” a voice said. “It’s Chase. Give me a call back as soon as you can. I’ve got a favor to ask.”
Dex sighed and clicked over to his directory, returning his boss’s call.
“Hey Dexter,” Chase said after picking up the call. “I need to see if you can run over to a bank president’s house and look at why his laptop isn’t booting.”
Dexter said that he would be happy to and got all the pertinent information. “Alright, I’ll update you when I get finished.”
He sighed after hanging up and went downstairs. Heading outside, he went out to where Jessie was laying out and knelt beside her.
“Hi,” she said, smiling and reaching for him. He leaned over and kissed her. “There’s some bank president that has a laptop that isn’t booting and is requesting help. I told Chase, my boss, that I’d go take a look. It’s probably not anything serious.”
She nodded. “Okay baby,” she said. “I’ll just keep doing what I’m doing.”
He kissed her a final time and grabbed his work stuff after changing into something a little nicer. He was surprised when he finished though that it took him longer to drive over to the house than it did to fix the laptop. The bank president, as with a lot of bank presidents, wasn’t really all that tech savvy when it came to computers. Dex fixed the issue and after receiving several heartfelt “Thank yous” and a hearty handshake, he drove back home.
It had only been about thirty minutes total that he was gone, but still, he wondered what kind of mischief his girlfriend had been able to get up to while he was absent, realizing that he was a little hopeful that she had. Dismissing the curious thoughts as he pulled up to the curb, he hoped that Jessie and his dad wouldn’t hear him. Leaving his stuff in the truck for the time being, he quietly walked up to the door and peered through the front window. Seeing the hazy form of his dad through the translucent glass, he saw that he was heading out back and smiled. Opening the door just as his dad was closing the back one, Dex stopped and made sure that he wasn’t aware before he entered and went immediately upstairs.
He went to his dad’s room and walked over to the window overlooking the pool. Jessie and Don were close enough to hear as well, so he quietly cracked the window open.
He could see that his dad was standing near Jessie, who was still very nude.
“You’re gonna need some of this if you stay out any longer,” Don said, holding out a bottle of sunblock.”
“Oh!” Jessie said. “I totally forgot about that!”
Don chuckled and held it out for her. She smiled and turned over to her stomach. “Would get my back first?”
Dex could tell his dad was torn but wasn’t surprised by his girlfriend’s actions. He pressed himself into the curtain, hiding his form should they happen to look in his direction.
“Sure,” Don said, still obviously hesitant. He stepped over and popped open the sunscreen. Pouring some into his hand, he rubbed them together to try and warm it up before laying his hands down on Jessie’s shoulders.
Dexter couldn’t help but admire how gorgeous and sexy she looked. She moaned as Don’s hands made contact with her shoulders and started rubbing the sunscreen in. He could see the curve of her breast as it pushed into the lounger, and her skin was relatively pale in contrast to the brown wood of the deck.
Don’s hands rubbed and massaged Jessie’s skin as Dex watched. His girlfriend’s animated whimpers and moans were exciting, and he smiled as his dad continued to rub her down. He worked from her shoulders down to the small of her back, and then around and upward, barely moving up toward the sides of her breasts. He made another pass over the skin he’d just covered, and then moved down past her naked butt to her legs. Squirting some more lotion into his hand, he rubbed her pale skin for a few minutes until it was nice and spread out over her body.
“There you go,” he said, offering her the tube.
Dex saw her roll back over and smirk. “You didn’t get my butt yet,” she said, turning back over.
“You can reach your own rear,” Don commented. Dexter was proud of his dad in that moment. Other guys probably wouldn’t have been so noble given the lengths he knew his girlfriend would go to tease and flirt with someone.
“Well where’s the fun in that?” she asked. “Are you saying you’re not going to do this after I cleaned your house for you?”
Don sighed. “You know, I could say that I changed your oil and checked your car for you and now we’re even.”
“And I could remind you that you’re being asked to put your hands on a nude woman’s body,” she pointed out. “Don’t pretend you don’t want to.”
Don hesitated, but Dex could see an obvious smirk appear on his face. He popped the lid of the tube open again and poured some more into his hand. Rubbing them together to spread the lotion out and warm it up a little, he raised an eyebrow at her.
She giggled and laid flat again once she’d seen that she’d won. She lifted briefly to adjust her breasts underneath her, but then laid down flat again.
“Okay,” she said. “Go ahead and get your pervy butt-rubbing over.”
Don sighed and shook his head, then smirked and brought his hand down on her bare ass. A loud smack and a shocked giggle later, he was massaging Dexter’s girlfriend right on her plump butt. Dex smiled. As flirting went, he figured that this was pretty innocent. Besides, she’d already admitted that he’d had to jerk off in front of her. Still, he didn’t know if she was a hundred percent serious about that, but it hadn’t bothered him as much as he figured it should have, looking back.
Don rubbed his hands slowly over Jessie’s adorable butt, finishing it off with another spank, this one much gentler.
“There you go,” he said. Jessie smiled and turned over, laying on her back.
“There you go,” she said, smiling and looking up. “You’ve got another side to do.”
Dex chuckled quietly. He’d figured that she’d push it a little more.
Don sighed audibly but Dex could tell that he obviously wanted to. An invisible war of willpower was being fought within him.
“I suppose it’s useless to argue,” Don said at length. “Are you sure?”
Jessie looked at him incredulously. “Of course I’m sure, Don. Get to rubbing.” She laid back then and closed her eyes, a sly smile on her face as she tried to appear nonchalant about the whole thing; like it was normal for a father to rub down his son’s naked girlfriend.
Dex watched as Don poured some more into his hand and prepped it, then started on her shoulders and worked down, moving around her breasts. Surprisingly, his dad moved around her breasts and down, and then back up and across them, rubbing haphazardly.
Jessie giggled and moved her hands up, clamping them down on Don’s and pressing them to both of her breasts. “They’re just boobs,” she said. “Dex already knows that I made you jerk off in front of me and that I clean naked around the house. You really think he’s going to be upset that you grabbed my boobs?”
Don didn’t say anything, a smirk on his face. Jessie laid her hands back down at her sides as Don’s hands moved over her body. He worked the lotion into her breasts, even surprising Dexter with a little nipple play. Moving downward, he slowly worked more and more lotion into Jessie’s pale skin.
Dexter realized then that he was watching another man rubbing his hands over his own girlfriend. Not only was he watching it, judging by the intensity of his current erection, he was thoroughly enjoying it.
Don played with Jessie’s breasts a little more until the skin was glistening with sunscreen residue or sweat. Getting more lotion from the tube, he began to coat her legs and thighs.
Jessie seemed to really be enjoying his ministrations. Small moans and whimpers that Dex easily recognized as pleasure could be heard from his vantage from the second floor window.
“There you go, spitfire,” Don said. He stood up from the chair where he’d been sitting and smiled.
Jessie looked up and then sat up, smiling playfully. “Are you going to go swimming?” she asked.
Don looked like he was considering it for a moment, but then shrugged. “I think I’m good.”
“Oh come on, Don,” she said. “Let me let the sunscreen dry and we can get in together.”
Don chuckled. “I don’t think you want me stripping right now.”
Jessie smiled wider. “Oh really?” she asked. “Do you have a big ole’ boner just for me?”
He laughed easily and shrugged. “I’ve been rubbing a nude knockout down for a half-hour,” he pointed out. “Of course I do.”
“Aww,” she said with a playful pout. “Well, take that gorgeous cock out and let me see!”
Don smirked and shook his head. “I don’t think Dex would like that.”
“Dex gets to fuck my roommate whenever he wants. He gets head from me like… all the time.” She looked up at Don seductively. “Please,” she said. “I promise I won’t touch it.”
Don looked down and stared quietly for a minute, no doubt having another quiet willpower struggle. Sighing, he stripped off his t-shirt as she giggled and clapped excitedly. Dex watched as he dropped his shorts after kicking off his flipflops and chuckled as he saw that his dad did indeed have an erection.
