I moved back in with grandma shortly after our first night together. I moved into the guest room, but I spent most nights in grandma's big king-sized bed, making love and cuddling with my sexy grandmother.
I also started to do freelance technical work. I worked from home and set my own hours.
Grandma meanwhile was going all out to enjoy our new relationship. The more we experimented sexually, the hornier she seemed to get. Some nights I'd have to work late to finish a project and grandma and I would play a game: she'd do her best to tempt me into her bed, while I did my best to resist. One night, while I was busy coding html, grandma put new batteries in her vibrator and went to town. As I sat in front of the computer, tapping away, I could hear her moaning my name as she plunged the vibrator in and out of her pussy.
"Billy," Grandma called from her bedroom. "Pleeeeese Billy, come in her and take care of your grandmother. I neeeeeed you"
Needless to say, I didn't resist for very long and before I knew it we'd be tangled in a sweaty knot in granny's sheets.
Grandma had always been a sexy dresser. But now, she went out of her way to dress like she was halfway to the sack: short skirts, push-up bras, high heels, thongs, garters, corsets, boots, you name it. She threw out her old cotton sheets and bought a whole collection of silk and satin sheets. Plus, she bought a new floor-length mirror on wheels.
Despite our energetic play between the sheets, grandma's real turn-on was flouting our taboo relationship. She never passed up an opportunity to let others glimpse our special love.
For instance, a couple of times a week grandma would suggest we pick up a quick meal at the local fast-food restaurant. This really just gave her an opportunity to show off our love in public. Grandma would sit next to me dressed in a low-cut blouse and short skirt as I wheeled the car to the drive-through pick-up window. Once I'd pulled up, grandma would lean across me and smile at the (usually) girl in the window. If it was a new girl, grandma would announce: "Hey, honey, this is my grandson. Ain't he a cutie?" Typically, the girl would smile uncertainly. Grandma would proceed to snuggle up against my chest, pushing her tits up into my face. Then, as she gazed at the girl in the window, she'd slowly run her hand over my crotch. "He's so handsome," granny would say to the girl, who was by now flushed and confused. "He really makes his grandma happy." With that, she'd give me a big, wet sloppy kiss with lots of tongue. I'd grab the change and food from the girl, who would be in a state of shock, and we'd drive off, with grandma giggling and stroking my cock.
About the fourth or fifth time we'd performed this act, we were greeted at the drive-up window by the manager, a chubby guy who sweated and licked his lips as he greeted us. Grandma went into her routine and the guy's eyes practically bugged out of his head. As I went to put the car in gear, grandma pulled my hand off the stick shift.
"Hey buddy," she said to the manager, as she leaned across me. "You like what you see?"
The manager gulped and smiled weakly.
With that, grandma took a quick peek behind us to make sure we were the only car in line and crammed her full, sweet tits into my face. Never one to miss a quick meal, I started kissing and nibbling her fat, full breasts. I could feel grandma's nipples growing hard beneath her blouse as I ran my mouth over her tits.
"Hmmmm," grandma moaned as she rubbed her tits back and forth across my face. "My grandson REALLY knows how to make his grandma hot."
I glanced over at the manager whose face was now bright red and covered in sweat. My cock started to harden as grandma began squeezing and massaging it. I reached up and expertly popped granny's tits out of her blouse. As I stared at her luscious breasts, my gaze fastened on her two puffy, thick nipples jutting forward right into my face. I fastened my mouth around one and sucked, licked, and nibbled it while I reached to squeeze both mammoth tits in my hands. I could feel my hips churning, almost involuntarily, against grandma's hands, and then I felt her pull my zipper down.
"Oh shit," I mumbled around her tits. "Grandma, we can't fuck here."
Grandma moaned, and I pushed her tits away from me as she now fastened her smooth, cool hands around my cock. I looked up to the manager, who was breathing hard and, evidently, playing with himself beneath the sill of the drive-through window.
"Sorry pal," I said to him as I shifted the car into gear. "Maybe later. We'll be back for the food."
The car lurched into motion as grandma bent down and fastened her lips around my cock, and we almost got home before I had to turn off onto a deserted street and let granny taste my cum.
Then there was the UPS guy. I guess he and granny had been flirting for quite a while before she and I started fucking. But because I was constantly getting disks and project specs overnighted to me, she had seen a lot more of him since I'd moved back in. He name was Joe, and he was a tall good-looking, athleticly-built black guy, probably around 30 or so.
One day, as I worked in the back bedroom of granny's apartment, I heard the doorbell ring and then Joe and grandma making conversation. I heard her giggle and then grandma called out.
"Hey, Billy," she said. "Come on out here, I want to show Joe something."
I smiled to myself and headed out to the living room dressed in my usual work attire, a pair of shorts and a tank top. Grandma was dressed in a sheer housecoat that revealed her red panties-bra outfit beneath. She was sitting on the couch and Joe was sitting in a chair across from her. Grandma patted the couch next to her.
"Well, Joe," granny said, looping her arm in mine and patting my forearm with her other hand. "You know Billy and I are very close for a grandmother and grandson."
Joe nodded and smiled, uncertain of what to expect next.
"Joe," Grandma asked with a wicked grin. "Have you ever seen a grandmother kiss her grandson like this?"
With that, she leaned over and plunged her tongue into my mouth. I reciprocated, and soon we were hungrily devouring each other's mouths. I pulled granny close to me as she wrapped her hands around tightly around my neck. As we tongue-fucked, I followed granny's gaze back, across the room to Joe, whose jaw had now dropped almost to the floor.
"What the fuck," Joe muttered, once he'd cranked his jaw back into place.
"Hmmmmm," grandma murmured, twisting around to face him. "Do you think we should, Joe?"
Again, Joe's jaw dropped. Grandma and I returned to our kissing. I was getting really turned-on at the sight of Joe sitting across from us, taken by complete surprise. My cock was quickly telescoping to its full, hard length. Grandma reached down through the waistband of my shorts and pulled it out. She groaned in pleasure and turned to see Joe's reaction as she started stroking my dick. Joe was breathing hard and licking his lips. His hand had drifted to his thigh, and I could see he was itching to start playing with himself.
As grandma stroked my dick, I pulled open her house coat and started playing with her tits. She moaned and slid her legs over mine so that she sat on my lap with her legs on the outside of mine. I reached down to take a cheek in each hand, squeezing and pinching her luxurious ass. I peeked under granny's shoulder to see that Joe had begun stroking himself through his shorts. I could see his big cock swelling up tight against the leg of his shorts.
Grandma meanwhile reached around her back with one arm and started playing with my dick and my balls. I wondered how far she was going to take this as I started to rotate my hips in pleasure and desire.
"Well, Joe," Grandma gasped as she turned to watch the UPS man over her shoulder. "What do you think? Uh. Don't you think we make a pretty sexy couple, my grandson and me?"
Joe just nodded and kept on stroking his cock.
Impatient and feeling my cock grow hard, I started pulling grandma's panties off her hips as she raised ass off my crotch to help. Suddenly, Joe's walkie-talkie squawked into life.
"433. 433," a loud staticky voice shouted. "Where the fuck are you Joe?"
Joe swore to himself and tried to ignore his dispatcher.
"Hey, numb nuts," the voice exploded from the walkie-talkie. "Get your ass in here . . this shipment for 244 Clason has been waiting for an hour."
Joe fumbled with the walkie-talkie and raised it to his mouth.
"Yeah," he muttered hoarsely. "Okay, okay. This is 433. I'm on my fucking way."
