"C'mon. Help me get him to bed," Margie said.
Supporting him between us, Margie and I led Bob down the hall to the bedroom and laid him on the bed. I went back to my barstool while Margie undressed Bob and put a blanket over him.
A few minutes later Margie emerged from the bedroom and closed the door behind her. I noticed that she had changed into a short, sheer kimono that barely reached to mid-thigh. She walked to the couch, sat down, and I joined her. Sensing my uneasiness, Margie said, "What's the matter? Nervous?"
"Kinda. Your hubby is asleep right down the hall. And, I've never been with an older woman before, especially a lady with grandkids."
"Forget about Bob. He won't wake up till daylight. I've never been with a younger guy before either. But I think I'm gonna like it. Bet you will too. Now, let's you and me have some fun."
We embraced. As we kissed I slid my hands under the kimono and cupped Margie's bare ass. As I fondled and played with her cheeks, Margie slipped her tongue inside my mouth. I sucked on her tongue as she worked my shirt over my head. I tossed the shirt aside and we sent back to kissing and fondling each other. I flicked my tongue inside her ear and rubbed the soft flesh on the inside of Margie's thigh. She parted her legs and I moved my hand higher, stroking her pussy. She let her hand drift to my crotch and began to rub. As she rubbed my cock through the fabric, she felt me grow hard. She slid her hand inside my shorts and grasped my cock. I stood up and shucked the shorts. Margie stood and I undid the tie on her kimono. She shook her shoulders and the kimono fell to the floor.
Wow, Margie didn't look so matronly now, I thought. In spite of her age, she looks damned sexy with her clothes off. Medium sized, pancake titties, kinda on the saggy side, with long, dark nipples and huge, mahogany colored areoles; a well defined but thick and chunky waistline; a slightly paunchy, round, soft tummy, perched above a dark, thick, well manicured bush; wide hips; a massive, soft, round, pillow ass; and thick, heavy thighs and legs. My girl friend is a slender, willowy type, with a runner's body so the contrast between them added to the allure.
We were both raring to go and knew we had to relieve the sexual tension that had built up between us. Margie grasped my hand and led me down the hallway. We slipped into the spare bedroom, and I stretched out on the bed while she closed the door and opened the drapes. Margie slid onto the bed next to me. She lay back and I licked, sucked, and chewed on her nipples. As they grew taut, I stroked her pussy. I felt her getting wet and ran my tongue down her chest, across her tummy, and placed my head between her legs. She spread her knees and I pushed my face into her bush, parting her labia with my tongue. Her pussy started to open up like a spring blossom. As it did, I plunged my tongue inside and began to work it back and forth, in and out. She gave off the aroma of a woman in lust. Margie thrust her pelvis into my face and I picked up the tempo, licking and sucking on her clit. In less than a minute, she arched her back, gasped, and shivered in orgasm.
She recovered quickly and pushed me onto my back. She knelt beside me, grasping my cock. She licked it a time or two, then slipped the tip inside her mouth. Bobbing her head up and down, she worked at it, devouring it, till she had the whole thing in her mouth. Then she cupped my balls in her hand and gently massaged them while she sucked forcefully on my dick, all the while deep throating me. I lay back and moaned. When I felt like I was going to explode, I pushed her off and said, "Let's fuck, baby."
Margie giggled and said, "It's about time. I thought you'd never ask." She sat up and took off her earrings and glasses and tossed them on the nightstand. She snapped on the bedside lamp, tossed one leg across my torso, straddled me, and sat on my stomach.
"Want me to wear a condom?" I asked.
She rocked back and forth, rubbing her wet cunt on my midsection. "Actually, I hate the damned things. No need to wear one, sweetie, unless you want to. I went through the change 10 years ago, so we don't have to worry about me getting knocked up. I haven't been with anyone other than Bob since we got married, so I'm clean as a whistle."
"I don't like condoms either. I prefer bareback," I said.
"Well then. That settles that," Margie said with finality. Reaching around behind herself, she grabbed my cock, rose up on one knee, balanced herself on the opposite foot, and positioned herself above me. She sat poised like that for a second, stroked my cock a time or two to get it a little harder, then licked her lips, flashed a lewd grin, and lowered herself slowly onto my shaft. She grasped my cock by the base and clutched at it as she worked the head inside her pussy. I was surprised at how tight she was. Even though I am only average in size, and we were both well lubricated from the oral sex and the foreplay, I thought she was never going to get it all the way in. Taking her time, she maintained her grip and pumped up and down with short, slow, rhythmic moves, working a little more cock in with each stroke. When she was almost there, she let go my cock and gravity did the rest. She gasped as she slid down the last inch or two. When I was all the way inside her, Margie flexed her pussy so that it grasped me like a fist. She thrust her pelvis forward and wiggled her ass from side to side until she got my cock positioned inside her just where she wanted it. "Mmmmm. God, this feels good." Margie purred. I agreed that indeed it did.
I put my hands on the small of her back and pushed until Margie leaned forward far enough that I could get a tittie in my mouth. She started sliding up and down my cock, fucking me slowly at first, then gradually increasing the tempo. I sucked first one nipple, then the other. Margie's nipples grew hard and swollen and she started panting. She fucked me harder, pumping up and down, heisting her ass high in the air, on the upstroke, and thrusting her pelvis forward on the down stroke. She pumped up and down harder and harder. Her panting turned to loud, guttural, huffing grunts. We were both getting hotter by the second. I grabbed her by the hips and thrust my cock into her as she humped up and down. Margie moaned and cried. She put her hands next to my knees and leaned back till her ass was pressing against her heels. Driving her hips forward so my dick was deep inside her, Marge squeezed her pussy tight and made circular motions with her ass, first in one direction then the other. She sat up, then leaned forward, and we locked mouths in a french kiss. She resumed her slow, deliberate, forceful humping. I grabbed an ass cheek in each hand and held on tight while she rode me.
Margie began to pant, moan, and whimper. Unnhhhhhh! Aaaaaaah! Ohhhhhhh! Yeeesssssssss!!! MMMMM! Ooooooooooh!" We were both on the edge of cumming, when we were interrupted by Bob's yelling, followed by the sound of him bouncing off the walls as he stumbled down the hallway and fell. "Margie! Where the hell are you?" he demanded, slurring his words.
Well, the jig is up I thought, trying to conjure up an escape plan. "Aw shit! Goddamn it!" Margie exclaimed, sitting bolt upright. With speed and agility that surprised me, Margie dismounted, grabbed a robe of the dresser, threw it over her shoulders, and slipped out the door. She looked, back at me and whispered, "Stay put, baby. I'll be right back." I heard her pleading with Bob to go back to bed. Eventually, I heard Bob's bedroom door shut, and in a minute or two Margie was back. She closed the door behind her, tossed the robe on the floor, and hopped back into bed with me.
