I leaned over onto her and reached around her for those tits, grasping one in each hand, lifting them, feeling their heft, and they were heavy, real heavy. I could feel the texture of her areolas as I juggled them on my fingertips. After giving each nipple a gentle squeeze and roll between my thumb and fingers I let her tits gently roll off my hands, smooth, soft skin sliding by my fingertips. Raising myself back up, I put my hands on her hips and went back to the long, slow strokes that had been shortened by my leaning over on her. Out to just the head of my penis in her then a long smooth stroke back to the hilt, over and over I drove into her. She was beginning to groan softly so I picked up the pace, still sliding almost almost all the way out but not pausing, hammering back into her hard and fast on each stroke.
"Damn, I wished there was some way to watch her tits," I thought. "I bet they're swinging like mad." I could feel her beginning to shake under me, butt cheeks alternately flexing and relaxing as I hammered her from behind like a pile driver seeking bedrock.
"I want you to cum in me, Bobby. Sow that seed as deep in me as you can. I want to feel your cum hit me, hit me deep inside," she was saying as I was approaching my orgasm. All at once, I couldn't maintain my smooth steady stroke, becoming irregular as I felt my testicles tighten up. One last stroke and I buried myself to the hilt, involuntarily pushing into her with each pulse of my penis setting loose its load deep within her. I stood there for several moments, feeling her pussy squeeze and release on my penis. It felt like heaven. Pulling back, my penis dropped out of her to swing down, slinging a big drop of cum onto the floor.
"Very good," I heard from the direction of the door. "Liz, you always were the sluttiest one of us three." Looking toward the door I saw Vickie and Gram standing there looking at us.
"Yep, I guess I was. And it was worth it. Maybe you should try it. You'd find it a damn sight more satisfying than that vibrator of yours," Aunt Liz shot back as she bent down and picked up her housedress. Without donning it she walked past Vickie and Gram and out the door toward the house.
"Maybe I should," Gram said, "But not right now after you've used him up," as she turned to follow Aunt Liz toward the house.
Vickie stood there looking at me as I approached her. "Aunt Liz is a lot hotter than I figured," she said.
"Oh yeah," I replied. "Did you get load of those tits on her?"
"Yeah, I saw. I guess mine won't be good enough for you now," she replied.
"Yeah, right," I told her as we headed for the house, my arm around her shoulders. Back in the house we found Gram and Aunt Liz sitting in the living room, Liz still naked, sitting on her housedress on the couch.
As we came into the room I heard Aunt Liz saying, "...Becky and Julie over here." Becky and Julie were Gram and her sisters' best friends. They'd all hung together since elementary school and were very close.
"What's that?" Vickie asked.
"I was telling Martha here that we needed to invite Becky and Julie over here to see you kids. They haven't seen you since Christmas," Aunt Liz said. Now with us staying with Gram for several weeks and as often as the five women got together there was little doubt they'd be seeing us. So it wasn't exactly something that needed to be done, I thought as I sat down on the opposite end of the couch from Aunt Liz.
"When?" asked Vickie.
"How about tomorrow afternoon?" Gram asked.
"Great," Vickie answered as she sat down on the couch up against me between me and Aunt Liz. She immediately put her hand on my leg, palm on my thigh, fingertips grazing my penis lying between my legs. As we all sat there, Liz, Vickie, and me naked, Gram carried on like it was perfectly normal for her to be sitting there dressed with three naked people sitting opposite her. The conversation just went on like normal though I was beginning to engorge a bit as Vickie continued to lightly stroke my penis with her fingertips. As my penis climbed off of the couch cushion to stand out in between and parallel to my thighs it wasn't lost on Gram.
"Good Lord, Bobby," she exclaimed, "Doesn't that penis of yours ever get tired? Liz, it's starting to come up again, for goodness sakes. I would have thought you might have put it down for awhile after your trip to the barn."
"Martha, maybe you need to make a trip to the barn with the boy," Aunt Liz told her, "Maybe you can tire it out for the night."
"I think you might be right, Liz," Gram replied. With that she stood up and said, "Come on, boy. Let's go take care of that thing." She headed for the back door with me following after her, but rather than going out to the barn she went only as far as the back porch, motioning me toward the day bed out there. "Over there, Bobby. It's way more comfortable than the barn, I think." I sat down on the side of the day bed and watched as Gram began removing her clothes. She unbuttoned and pulled off her long sleeve blouse, exposing a massive, snow white bra. After folding the blouse fairly neatly and placing it on the rocking chair, she unbuttoned and unzipped her jeans and pushed them down her legs. She was wearing white granny panties that she pulled down and off after laying her jeans neatly on the chair. As she straightened back up I saw that she had a belly like a little pouch that hung down a little but then she reached around behind herself and undid that bra, that massive bra and as she let it fall down her arms her huge, pendulous breasts dropped free. I stood up as those tits swung free. They were massive, absolutely huge with areolas that must have been at least four inches across. They hung down onto her belly with the nipples seeming to be staring down at her feet. "Now, if looking at this body doesn't scare away that erection, maybe you can put it to good use making an old lady feel good, young man," Gram told me. Rather than being scared away, looking at those ponderosa sized tits was making it harder. Gram noticed it moving upward and reached out to grasp it as she turned her back toward the day bed, sat down on it, then turned and reclined onto her back. Pulling gently on my penis, she said, "Come on, Bobby. I'm real sure you know what to do," as she was fingering herself below the full bush of graying hair. She didn't release her grasp on my penis as I crawled onto the day bed and between her splayed apart thighs. Pulling, guiding, she had me sliding into her as I lowered myself on my knees and hands. "Go on, Bobby. Show Gram what you can do for her," she coaxed as I began to thrust in and out slowly. "Yeah, that's it, boy," she said softly as I began to build up to a bit quicker pace and more forceful thrusting. It seemed like I had a full head of steam, like the more I fucked, the more I could fuck or something like that. Like Aunt Liz, Gram was able to take my entire erection to the hilt.
Gram's tits were hanging off the sides of her chest and as I began to hammer her harder, they swung back and forth, back and forth in time with the impacts of each of my strokes. My old Gram was turning me on, watching her jiggle a bit with each thrusting blow. I continued to hammer her, swinging my ass like a pendulum to keep up the rhythm of the strokes and conserve energy. Each impact sent her tits swaying and she was beginning to blink her eyelids slowly as she stared directly at my eyes. My strokes continued unabated, the swing of my ass providing the timing and force of each thrust, Gram's eyes never leaving mine until she began to tremble and shake under me, arched her back, and closed her eyes. Gently and slowly I continued to stroke the full length of my erection as she finished her orgasm. When she opened her eyes she smiled at me before saying, "Stop now, Bobby. I want to do what your grandfather really liked." I stopped and slowly pulled out of her before she rolled out from under me and said, "Here, lie down her."
I laid down on my back on the day bed and Gram crawled onto the bed between my legs, bent over, and began to suck on my penis while stroking it with one hand and fondling my testicles with the other. As I felt her gently juggling my testicles in her fingertips and sucked and stroked, I was quickly rising toward my own orgasm. Within a few minutes I felt myself cumming, my penis pulsing in her hand and mouth, and heard her swallowing as she took whatever load I had to deliver. She continued to suck gently on my penis after I finished cumming, then gently laid it down on my abdomen and sat back up. "There, how was that? It seems I haven't forgotton how to do that," she told me. She got up off the day bed, patted my leg and said, "Come on, Bobby. Let's go back inside." I swung my legs off the day bed and sat up but had to sit there for a moment because I felt a little dizzy. Gram had picked up her clothes and walked inside.
