One evening as Rick came in from work, Jill informed him that they had received an invitation in the mail that day.
"Great! Whose boring wedding do we have to attend now?" Rick asked
Jill told him that it wasn't a wedding invitation, but an invitation to his very own little brother's high school graduation party.
"Jeez, I guess I'd totally forgotten that Billy graduated this year. If I know mom, she's going to throw him a huge bash." Rick said
Jill said, "She figures that by the time of the party the first week of June, it will be warm enough to make it a pool party."
Rick's mother had done an exceptional job of raising Rick and Billy. The boy's father had left her penniless when he abandoned them for dreams of riches in Las Vegas. After some lean years Phyllis has gotten her real estate license and made a killing in the home market. Rick knew his mom's looks hadn't hurt her career either. She was a statuesque blonde with a figure that drew stares from men wherever she went. As her hair began to turn a bit gray, Phyllis had it colored platinum blonde. This along with her D cup tits and legs that seemed to go on forever made her drop dead gorgeous. Rick was never more proud of his mom when she purchased her elegant new home with the well manicured grounds and in ground pool. He would smile to himself as his and Billy's friends openly ogled their mom while she sunbathed in the skimpiest of bikinis.
"Your mom is so sweet." Jill interrupted Rick's thoughts "She included my mom in our invitation too."
The graduation ceremony was on a Saturday afternoon. Rick escorted Phyllis, Jill and his mother in law Karen. They were all dressed to kill. Rick knew Jill was wearing a garter belt and hose under her dress. He would have bet money that Karen was dressed the same way. He thought he detected the tell tale garter stretched across his mom's ass as he held the car door open for her. Phyllis looked stunning in a business suit that consisted of a jacket and shirt that stopped just above her knee. It was a subtle shade of gold. Under her jacket, which she kept buttoned, she wore a flesh toned lace camisole. If it were completely open her big tits and nipples would be plainly visible. Rick couldn't help himself from stealing glimpses of his mom's sexy legs as she sat in the front seat as he drove.
The ceremony took far too long in Rick's opinion. Once it was over he gave his little brother a congratulatory hug and told the group it was party time.
"Mom, can I bring my girlfriend Patty to the party?" asked Billy
"What a silly question!" Phyllis scolded Billy "She and all of your friends are invited!"
When they arrived at Phyllis' home, Rick was amazed at the preparations she had made. A huge buffet was laid out on the patio by the pool. Every kind of drink imaginable was available too. As the booze began to flow, the music began to play. Rick chuckled as he watched all of Billy's horny friends line up to dance with his mom. Some were painfully bashful, while others took the opportunity to pull her close and feel her big tits against their chest. Rick went over and asked Billy's girlfriend Patty for a dance. She was a cute little redhead with a sweet little round ass. As for tits, she had what Jill often described as "perkies". Rick could feel her hard nipples poking out as they danced close. Rick let his hand drift down to rest on her ass as they moved with the music. Figuring she would quickly abandon the dance floor, Rick was pleasantly surprised when she ground her pelvis into his. When the song was over, she kissed Rick and slipped him a taste of her tongue.
Karen was the next one Rick approached to dance. Just as he had suspected, Karen was wearing the sexy under things that Rick loved. He let his hand rub freely over her ass as they danced. When he was sure no one was watching, he reached inside the slit in Karen's skirt. He made his way through her thick bush and gave her clit several strokes. Karen buried her tongue in his mouth to stifle her moan. The rest of the dance was spent dry humping his mother in law on the dance floor. When Rick finally got around to dancing with his wife, she wanted to tell him of her and her mom's plans.
"Mom and I have an idea about Billy's graduation present. We have both had a dance with him, and both felt his hard on through his pants. Mom and I want to fuck your little brother silly before the night is through!" Jill said to Rick
"On one condition." Rick replied "I get to watch!"
"Hell sweetie, you can join the fun if you want." Jill giggled
