"It's a special day as we celebrate Tamara's tenth year with the firm!" the invite read. Mike scanned through the email as he strolled to his car that Saturday morning. He had read through the cryptically worded message dozens of times over the past couple weeks but couldn't completely understand what the line "...bring an open mind and a full sack..." was hinting at.
"You'll have a special job for me," his step-mother had explained earlier in the week. "Just show up with that can-do attitude and everything will fall into place, you'll see," was all she would cryptically explain, though.
Almost two months had passed since the night of the auction and things had really opened up for Mike since then. He had assisted Hillary, his parents, and Stacy in closing several deals over the summer. He and Hillary didn't really have to sneak around the house anymore, now that their parents knew they were fooling around, but they still did just to keep up the excitement. To top it all off, the family now had a clothing optional policy at their indoor pool, so Mike occasionally got to see his step-mom's solid gold tits just by getting downstairs in time for a morning swim.
Mike had no idea what was going on for this anniversary party, though. It was hard to believe it was fifteen years since his own mother passed away and another eight since Tamara married his father. He had to run errands that morning to make sure all of his clients were in good shape before he returned to school for the fall semester. By the time he returned home, several luxury cars were parked to the side of their curved driveway and a limo was dropping off a couple in what looked like expensive beach cover-ups at their front door. That could only mean something was going down in the family pool. Mike hurried through the empty kitchen, sensing the excitement in the air. Caterers were scurrying through the kitchen in black tuxedos and small black masks.
Upstairs, things were calm other than the occasional laughs coming from Stacy's room. She and Hillary were certainly up to something in there but Mike had no idea what was going on. He showered and quickly changed into a t-shirt and a tight pair of swim trunks.
When Mike reached the pool area, the music was bumping and the party was already swinging. In a deck chair on the other side of the pool, Maria from the reception desk was sitting naked in the lap of Ted, the firm's accounting department director. Her round tan tits were falling into his hairy toned chest. Up against the edge of his side of the pool, Mike watched Dana, one of the senior partners, teasing the hard cocks of two men whose backs were to Mike. Her tea drop breasts sagged just a little but he enjoyed watching at the naked middle aged woman enjoy her work.
Mike dropped his towel to a deck chair and continued to explore the space. He turned a corner and entered the theater room just off the pool area. Inside the room sat several of the firm's real agents on the leather theater benches with their cocks in their hands, jerking themselves off while they watched something projected on the screen in front of them. Mike walked down the aisle between the men and their tall hard dicks and turned back to look at the screen.
In front of him was a video playing of his father and step-mother fucking. They looked to be several years younger in this video. Tamara was leaner and her breasts weren't as full and his father was several pounds lighter, as well, with fuller hair. Someone else was filming his father's meaty cock pumping in-and-out of Tamara's tight opening. Her breasts bounced as he thrust into her on a bed that Mike recognized from an earlier arrangement of their bedroom decor . Mike could hear the mens' hands slapping against their bare skin while they wanked to these images of his naked step-mom getting pounded by his dad.
When Mike returned to the pool area, a few cat calls shot up as Stacy and Hillary entered the pool deck. Stacy was wearing the same high waisted throwback cheetah print bikini she wore to the beach when they had teamed up with the Diazes. The gold top held back her round dark brown cleavage. Hillary wore a blue and white striped one piece that fit tightly to her boney hips and hand a plunging neckline that covered her pert breasts with only thin strips of fabric. They held hands as they crossed the pool deck to Mike.
"Nobody told you, yet? We're the warm-up," Hillary flirtily informed him before pushing him down into a deck chair.
She turned to Stacy, reached around to softy take a handful of hair, and then kissed Stacy passionately on the lips. Naked couples all around the pool froze to watch the two young agents' sapphic display. Ted, the firm's effeminate design expert who'd been known to flirt innocently with Mike on more than one occasion, stood up from a nearby chair and untied Stacy's bikini top. She pulled away from Hillary for a moment to allow him to pull it away from her delicious breasts and Hillary replaced the top's support with her own hands.
The pair went back to exchanging long delicate kisses and Hillary fondled Stacy's nipples. Hillary turned around and grinded her ass into Stacy's crotch in rhythm to the bass of the pounding music. When Hillary stood up, Stacy pulled open the tie at the back of her neck, letting the fabric covering her breasts fall to her waist. Hillary's fair skinned breasts jiggled as she sook her ass. Slowly, Stacy pulled on the material around Hillary's waist. It unfolded down past her hips and then Stacy slid the fabric all the way to the floor letting everyone with Mike's view a look at the top of her friend's bare pussy lips.
"OK, you've all waited long enough, let's go," Stacy announced. Mike could hear the pool loungers and players exiting the pool and leaving their chairs. Hillary took Mike's hand as they passed and headed toward the theater with him in tow.
When Mike and HIllary reached the theater, the men inside had rearranged the furniture. The leather benches were now up against three walls of the room. Against the wall under the screen was an inclined cushy leather inclined bench with fixed stirrups on either side of the bottom.
Hillary worked the room, saying hello to several of the older men sitting on the benches and flirting with the clients and their wives who were filing in with drinks in one hand and their husband's cocks in the other.
"OK, who wants to help my mom celebrate ten years with the firm?" She asked, circling the middle of the room. A cheer rang up. "Awesome. If you want to kick this off, then I'm going to need see some big hard dicks!" With that, Hillary pulled Mike's trunks to his ankles, eliciting another round of cheers. She winked at Mike from her knees and then slipped her mouth over the tip of his penis, sucking at the top while she played with his balls with the tips of her fingers..
