Rick pulled into the driveway of his family's home at 1:30 am. He had decided to make the trek from State University and surprise his family on Christmas morning. He was tired and road-weary from the drive. He couldn't wait to climb into his bed and get a few hours of sleep before the festivities of Christmas morning.

As he entered the mudroom adjacent to the kitchen, he noticed a faint light emanating from the open refrigerator. He heard someone rummaging in search of a late-night snack.

Rick spied a dark-haired, Rubenesque woman in her fifties wearing a very sheer nightgown and revealed that she was pantiless. Every dimple of her ample ass was visible under the nightie that ended at the top of her thick thighs.

"Mom?" Rick asked softly.

The woman suddenly turned around, and her look of surprise quickly changed to a wide smile and gleeful eyes.

The see-through fabric of the gown revealed pale shoulders splattered with freckles that cascaded downward into her cleavage. A faint tan line separated her chest from her large alabaster breasts, which showed signs of gravity and aging. Her tummy was slightly round and flowed into the flabby midriff of her torso, which created a crease separating it from her pubic area. She might as well have been standing nude in front of Rick.

"Aunt Lillian!" Rick said in a low tone!

"Oh my God, Rick!" Lillian responded as she made her way towards him and gave him a big hug.

Rick was still processing seeing her aunt's voluptuous body practically naked, and he was surprised to feel the sensation of arousal in his groin as she pressed her body against him.

Lillian stepped back and clutched each of Rick's biceps.

"My," she said. "Look at you! You're so grown up! I didn't think you were coming for Christmas?"

"I wasn't at first, but nothing is going on while school is on break. So, I decided to come home and surprise Mom," he explained. "What about you? Mom said nothing of your visiting."

"Yes, well. I have been pretty lonely after Jack left me at the beginning of summer. I wanted the company of family for Christmas," Lillian explained.

Rick looked her in the eyes and said, "Aunt Lillian, I would love to catch up, but right now, I just want to hit my bed and get some sleep."

"Oh, um," Lillian hesitated. "I am staying in your room, and your aunt and uncle on your dad's side have the guest room," Lillian said apologetically.

Rick sighed, "I guess I am taking the couch. I will need some stuff from my room."

"Sounds good," Lillian said. She gave Rick a peck on the cheek and made her way to the staircase.

Rick climbed the stairs directly behind Lillian. Her practically nude ass sashayed in his face as they ascended. He became enamored with its roundness and width. He wouldn't consider her ass fat, actually; it was perfect for her age. He fantasized about how it would be to have his cock embedded in the hole between her two bountiful cheeks.

An erection started to stir as the image in his fantasy played out. Then he quickly put it out of his mind.

The bedroom was lit by a single lamp, which cast a soft glow over the room, creating a conducive atmosphere for relaxation.

Rick spotted a pair of panties lying on the floor next to the bed, which Lilian moved to retrieve. In doing so, she had her back to Rick, spread her legs for balance, and bent over to pick them up. When she did, her cheeks and thighs parted, exposing her vulva and vagina. In the same instance that Rick was exposed to his aunt's pussy, he noticed a sex toy in the shape of a penis on the nightstand next to the bed.

"Aunt Lillian!!" he exclaimed. "What the..."

She cut him off with a "Shush. Try to keep it down. You don't want anyone to overhear you."

Lillian noticed how he was looking at her in her see-through nightie and how he couldn't look away. She also observed the bulge in his pants as it became bigger and harder. She was getting moist thinking about it.

"Rick," she said softly as she approached him. "I am just a lonely mature woman who still has some fire left in her, but no one to help extinguish the flame. I know I don't have the hard body of a supermodel, but that hasn't stopped you from looking, and I think you're enjoying what you see."

She gave him a peck on the cheek, and he felt her hand latch onto the hard-on that had formed in his pants.

She moved her next kiss to his lips, and he accepted it as she stroked his encased cock.

Rick was surprised by his own response to Lillian's aggressive advances and was increasingly aroused by her overt flirtations and the eroticism of viewing her semi-nude, mature body. He was horny.

Lillian worked feverishly to unbuckle his belt and unzip his pants as their making out progressed. When she got the button undone, she whipped his pants down to his ankles and fell to her knees.

"Oh my God, your cock is beautiful," she said before devouring it.

Rick let out a gasp. He was no rookie to receiving a blow job, but Lilian's skills were extremely pleasurable.

He watched her take all of his six inches deep into her mouth.

She withdrew for a second to say, "You are so hot, and it has been forever since I sucked a nice cock!"

Lillian continued to stroke him as she moved to his balls. The musky scent of his scrotum turned her on even more, and she started to masturbate as she serviced him.

Watching his aunt go at it was amazingly erotic, and he felt the tingling of an orgasm welling up in his groin.

"I'm going to cum if you don't slow down," he said to her.

Lilian backed off and took a breath.

"Take off your clothes and go lie on the bed," she directed.

Rick did as he was told, and she disrobed as she walked over.

Completely nude, Lillian climbed onto the bed and straddled Rick. She spread her legs and leaned back, exposing her vagina. Rick was surprised to see that her pubic hair was trimmed to a small strip above her slit.

"Do you want to fuck my pussy, Rick?" she asked.

Lillian didn't wait for an answer as she grabbed his cock and guided it towards her hole, and lowered herself onto his boner until their crotches met.

"You are so deep inside my cunt," she whispered.

Lillian started to ride. Juices from her pussy dripped down Rick's shaft each time she raised herself, only to lower until he was as deep as he could go.

She felt her own orgasm welling up, but she didn't want to cum while on top.

Lillian climbed off and lay on her back on the other side of the bed. She spread her legs and rubbed herself.

"I want you to get between my legs and fuck me, Rick," she uttered. "I want you to fuck me hard!"

Rick positioned himself between her legs and slid his cock in her wet pussy. He ground deep inside of her and enjoyed the feeling of gyrating against her crotch. He started to hump her, and increased the speed and force with which he was fucking her. He propped her legs up from behind her knees and was banging her hard. He could feel his orgasm welling up, and he knew he would be shooting a big load.

Lillian was biting her lip, trying not to scream. She moved a hand down between her legs and used two fingers to touch her hard clit. The walls inside her vagina constricted with the onset of her orgasm. She shook, and her whole body writhed with pleasure.

Rick reacted to her orgasm with his own. His cock throbbed inside of her as it squirted his spunk inside her cunt.

They stayed entangled as their orgasms subsided and slowly caught their breath.

"Wow, that was awesome," Lillian said in the afterglow of their sex. "You'd better get down to the couch before we fall asleep."

Rick slept unnoticed on the Family room couch, and he awoke to the sound of voices and the smell of bacon coming from the kitchen. He surprised his family when he joined them at the breakfast table. Lillian joined late.

His parents and aunt, and uncle were planning a trip to the farmers' market for a Christmas craft show and invited him along.

Rick declined the invite, looking at Lillian across the table.

"I am afraid I am going to pass too," Lillian said with a gleam in her eye focused on Rick.

Catching the hint, Rick thought, "This is going to be the best Christmas visit ever!"
