On the day of Tyler's graduation party, Brian and Liz arrived at his house early, simply because Brian was anxious to see his parents and sister. Liz didn't complain too loudly since she'd be able to at least see Tyler, even if speaking more than a few words to him would be impossible.
She had plans to simply park herself at a table with the children and supervise them while Brian was monopolized by his family. Liz would ignore the teenagers, hoping that Tyler would also ignore her, thus keeping his mom and anyone elses in the dark about their relationship.
There would be no forlorn glances between them if she could keep him at bay.
It didn't quite end up that way, despite her best intentions.
Unfortunately, when they arrived and she sat down with the girls, Austin spotted her from his vantage point near the pool filled with bikini clad girls and sauntered over to the table. He wasn't a teenager, but still part of Tyler's group of friends and obviously invited to his party.
Liz did expect to see him here, and her eyes widened when he sat down with them. There was no way she could explain his presence to anyone, and she glared at him, despite the wide grin on his face.
After the night that he'd arrived home from vacation early and had joined Liz and Tyler in bed, the three of them spent several additional hours together before Liz had to go back home. During the last two weeks she'd spent a few evenings back at his house. Not much actual running had occurred during those weeks. Her exercise had come in a different fashion.
Tyler had been there for every night except one, and Liz found that surprisingly, she didn't mind his absence at all. Which made her feel a bit awkward with Austin sitting here with her now. His eyes on hers. Remembering his thick cock in her mouth, and various other places, made her blush and dip her head to avoid his eyes.
"Hi Liz." He said, "Shall we talk about the best fertilizer for grass, or something else innocuous?"
"Girls," Liz motioned at her two, "Why don't you go get some food from the buffet? I'm sure you're hungry."
Both nodded and bolted from the table, eager to find lunch and some treats, leaving the adults to have a boring conversation.
"I'm hard, sitting here at the table with you." Austin commented, almost offhandedly, but with a devilish look in his eyes. "I'd love to swim naked in the pool with you, and fuck you up against the side, with the warm water all around us. If only we were here alone."
"Jesus Austin. Knock it off. My husband's entire family is here. All I need is for one of them to wander over and hear you." Liz scolded him impatiently. "Why don't you go back and flirt with someone your own age today?"
"I already have. They're boring, vapid creatures. Far too concerned with their hair and cellulite." He waved a hand in the direction of the younger women. "I like my sex partners well-seasoned. Much tastier. And you taste so fucking sweet."
Despite their surroundings, Liz squirmed in her seat, aware of the heat in her face and elsewhere. "Seriously, you have to stop. This is not the place."
"Oh, I think it might be." Austin shifted in his chair. "I happen to know that there's a bedroom downstairs with a lock on the door. We can be in and out in five minutes. I know how fast you cum. Up against the door, it won't take long."
Imagining herself, visiting with Brian's relatives, Austin's cum leaking out of her the whole while she chatted about inanities, made Liz absolutely soaking wet.
"Where's Tyler?" She asked, not wanting him to come looking for her while she was having a rendezvous with Austin.
"He's occupied, over there," gesturing towards the pool. "Some chick is hot for him and she's putting all the moves on him. He'll be busy for a while."
"Five minutes." Liz stood, her knees weak at the thought of what she was about to do, here in her in-law's house.
"Five minutes." Austin agreed, "Go down the stairs and turn right. I'll be seconds behind you."
With a quick glance at the girls, who had found some other children their own ages and were occupied with a board game, Liz darted into the house and quickly skipped down the stairs. She failed to notice Julie's husband Sam standing in the kitchen, observing not only her, but the almost immediate presence of Austin, following her into the basement.
A grin spread across Sam's face, and his eyes lit with a fire he hadn't felt in a long time. "Well, well. What have we here? The prim and proper Mrs. Liz having an assignation?" He thought to himself. "We'll have to see about that!" Positioning himself in a way that he appeared simply busy with kitchen tasks, Sam waited for them to return.
Downstairs, Liz found herself with her back against the door, lacy panties on the floor, sundress pushed up against her bra, and Austin's cock buried inside her cunt. Her legs around his waist, arms around each other as he fucked her, rapid thrusts, stifling any sounds either wanted to make with their mouths against each other.
"Five minutes." Austin reminded her as he came inside of her with a final thrust, her head banging gently against the hard wood behind her.
"Five minutes." She agreed, watching him step back and put his clothes back together. "You go upstairs, and I'll follow you this time. I need to clean up a bit."
"Thanks love." He kissed her and ducked out the door. "See you on the other side."
Liz laughed softly as she dashed into the bathroom, taking a moment to clean herself. She was still chuckling when she headed up the stairs to the kitchen.
"Hey Liz." She heard Sam call to her as she walked down the hallway towards the outside door.
"Sam?" She stopped and turned into the kitchen to see Sam chopping away at a tomato. "Hi there." Liz greeted him. Her husband's brother-in-law was an enigma. He had been married to Brian's sister for as long as Liz had known Brian, 'childhood sweethearts' she'd heard his mother say. Always working, usually missing as many holiday events as Liz tried to, she hadn't had much of chance to get to know him. Pleasant and hardworking is all she really knew about him.
Cute, in a dad kind of way, with sandy colored hair and blue eyes, she supposed he was attractive to many women. Today, he wore madras shorts with a light blue polo, bare feet on the tile floor as he sliced a few more tomatoes.
"What brought you downstairs?" He asked mildly and Liz paused, smile tight on her face.
"Oh, just exploring the house. I forgot how big it is." She replied, her tone as mild as his.
"It is rather." He smiled at her, teeth white in his tanned face. His eyes holding hers. "Big, that is."
Liz's body froze, instantly realizing that he wasn't talking at all about the house. Shocked at the blatant sexual innuendo he had just thrown her way. Obviously, he had observed her and Austin both going downstairs and had figured out exactly what they were doing. Or was bluffing, hoping she would just confess.
"I'm going to head out to the patio. I haven't had a chance to say hi to Julie yet." She said, adding, "Shall I take the tomatoes out with me?"
"Not just yet. Join me for a moment, will you?" He held out a hand and motioned towards the family room, adjacent to the kitchen.
