Jake was just an average guy. He and his wife had a good relationship, both out in public and in the bedroom. Tracy, his wife, was only interested in "normal" sex, and she had never allowed him to cum in her mouth. Jake was sort of bored.
Approaching the Christmas season, Jake's mother-in-law, Pam, came to visit. Each night after dinner, his mother-in-law would join he and Tracy to watch television. Pam always showed up in the living room at night wearing a bath robe, and barefoot. The robe was thick, soft and comfortable, and gave no hint of what was beneath the fluffy dark blue terry cloth.
One night, while Tracy was out with friends, Jake was watching television, totally involved in the show. He heard Pam come in, but didn't even bother to glance at her. What was there to see? She sat at the other end of the sofa.
Well, when a commercial finally came on, Pam asked
"Do you want me to bring you anything for dessert?"
Jake glanced over to answer, and saw that her robe was loosely fitting around her. He could see inside the top of her robe, which was falling open due to the way she was sitting. His pulse quickened.
"Um, yeah, uh, can I have some cake and a cup of coffee?" he said, while looking at the side of her right breast, pale white, lying flat against her chest.
"Sure thing! Do you want ice cream with that?" she asked.
Jake couldn't move his eyes. What he could see of her breast was making him hard. "Yeah, sure. Ice cream would be great!"
As Pam got up from the sofa, Jake got a quick glimpse of her breast, hanging forward against the robe. The mature sag of her C cups was evident. She wasn't wearing anything under her robe! At least above her waist!
After Pam left the room to prepare his dessert, Jake reached into his pajama bottoms and adjusted his now-swollen penis. He was hard, thinking about her.
Lost in thought, he suddenly realized Pam was returning with his dessert. He quickly removed his hand from inside his bottoms. Had he been caught??
Jake's heart was racing while Pam walked over to his end of the sofa. Jake could barely make out the motion of her breasts under her robe. He knew that he had to see more. She leaned forward to place the food on the small table near the sofa, and Jake was disappointed. He saw nothing. Her robe was now tightly closed.

Jake spent the next two days eyeing his mother-in-law in a new way. He realized that, despite being in her 60s, she had very nice tits. One day, she had on a thin red cotton sweater. It was clear that she also wore a bra. She'd stepped outside to the mailbox, and when she returned from the cold air, he saw that her nipples were hard. Even with her bra, her nipples clearly showed, sticking out, low on her breasts, pointing away and down. Boy were they hard!
This only made it worse for Jake. If he was lucky, he thought, he'd be able to glimpse Pam's tits again.
That evening, with Tracy again out of the house, Pam came into the living room to watch TV. Instead of sitting on the sofa, she sat cross-legged on a chair to the side of the sofa. Jake stole furtive glances at her mature milky thighs, trying to see if she was wearing any panties. He couldn't tell. That didn't stop his penis from responding!
After a few minutes, Pam once again offered dessert. As she got up to leave, Jake got a very brief view up her robe. Though he couldn't see clearly, he was pretty sure that he saw some pubic hair as she spread her legs and leaned forward to stand.
Jake's penis was throbbing, tantalized by Pam's mature beauty.

When Pam returned with his food, she wasn't wearing her robe.
Jake's heart started racing immediately! He felt flushed. His cock continued growing.
Pam had on some loose shorts, and a fitted white cotton tee-shirt. Her hard-nippled breasts, held tightly under the too-small and almost-transparent white cotton, bounced as she walked over to his seat.
"Oh my God!" he thought.
Jake couldn't make our her areola, but could see that her mature breasts were hanging down, and not too full. Pam's shorts were riding up high into her crotch, and the shape of her pussy was visible.
As Pam bent forward to place the food on the table, she glanced at Jake's crotch and asked "Honey, did you spill something?"
Jake glanced down, and saw he had a growing wet spot on his bulging pajama bottoms. "Um, no...", and he tried to move in his seat.
Jake could not stop looking at Pam's tits. They weren't particularly large, but they had just the right profile, just the right amount of motion as she walked, and some very hard nipples!
"Hey, why are you looking at my crotch, anyway?" he said.
Now it was Pam's turn to be embarrassed. She got a little flustered, and said
"Well, I couldn't help but notice when I put the food down".
She turned to walk away, and her shorts showcased her lovely mature bottom. The cotton of her tee-shirt was tight across her back. Jake's pulse was racing, looking at her, braless. She looked very sexy!
"I hope you don't mind that I'm not wearing my robe, but Tracy keeps this house pretty warm."
Jake thought his penis would explode at any moment. "That's fine Pam, as long as you're comfortable!"

After Pam sat down on the sofa, Jake realized he had no idea what was on the television. He was slyly glancing to his right side, eyeing Pam's tits. They were perfect! And those nipples! Laying apart on her chest, he clearly saw the outline of her breasts. Jake's penis was aching.
Jake decided to reach for a blanket and cover his crotch.
"Aren't you hot?" asked Pam.
"Not as hot as you are..." he responded, dropping a hint while spreading the blanket out. He reached under the blanket, and hoping Pam wouldn't notice, gently eased his erect cock out of his pajama bottoms. He just squeezed his hard cock, now covered in pre-cum, while glancing sideways at Pam's tits. Then, slowly rubbing a wet finger right under the head of his aching penis, Jake spasmed uncontrollably, and he felt hot cum spurting onto the blanket, and all over his hand. Still staring at Pam's tits, Jake's pulse was racing!
Just then, Pam looked over and said "Jake, would you mind scratching my back?" Jake felt like he was blushing, his heart still pounding.
She slid over on the couch, and sat next to him, but facing away. Jake quickly tried to wipe off his left hand, and with his right hand, started to scratch her back.
"Where does it itch?"
Pam responded "Up high, in the middle of my back"
Jake was scratching, and suddenly Pam said "You know, let me lift up this shirt. I don't want to embarrass you, but I'm facing away, and if my back is bare, it'll feel much better!"
