Sylvia's first big white cock, and my first t

I'm 39, swm, in great shape, real cute and have a nice thick shaved 8" cock. I've had an older woman fetish since I was in my teens, and have met and fucked a bunch of women online since I joined AFF in 02. 60+, bbw's...I've had some amazing sex. Big older women have the hottest, tightest pussies...and they love oral, cum super easy and hard, and they can almost always take a big cock hard and deep. For some reason though, I've never been with a black granny, it just never worked out. Last week though, I met a woman, Sylvia, on AFF. She's 67, 5'9", with big heavy tits and a wide ass and I couldn't believe my luck. She lives just a few towns over, and after we texted and exchanged some pics (she has fucking incredible tits...big dark nipples, and a fat little pussy with a grey bush), she called me. We talked for a good while, the whole time my cock about to explode at the thought of her naked. She was a little hesitant, but finally agreed to come over to my condo last Saturday afternoon. I met her at the curb and almost came when we hugged and she brushed her hand against the huge bulge of my cock through my shorts. I led her up to my place and we sat on the couch, sipping iced tea and shooting the shit. Unable to stand waiting any more, I leaned in and kissed her. She moaned and sucked my tounge into her mouth, her hand sliding up my thigh, squeezing my cock through my shorts as I reached under her blouse and cupped one of her huge tits. We got each other all worked up and she suddenly pushed me away, got up and shut the blinds. She pulled me to my feet and kissed me again, then stepped back and we watched each other undress. She gasped as she straightend from stepping out of her full white panties, my cock jutting out, rock hard and swollen. We came together and she grabbed my shaft and squeezed it as I lifted her tit to my mouth and slid my fingers up her thick thigh to her fat pussy. She groaned and stroked me hard as I felt her pussy get soaked, shocked at how tight she was as my finger slid inside her. I kissed my way down her tummy and dropped to my knees, leaning forward as she squatted and rolled onto her back. I held her under her thick thighs and explored her pussy with my mouth, finally landing to suck her hard, little clit, fucking her with my finger till she ground her hips into my face and squealed, cumming hard, sweating now. I crawled up on top of her and she gently pushed me so I rolled off, both of us laughing. She told me to stand up, and she got up to her knees in front of me. She grabbed my cock, and it sprang to life, throbbing as she stroked it and told me that she'd never seen one so big. She looked up at me and took the head into her mouth, sucking me as she slid her lips down my shaft till she gagged halfway down. She pulled back and rubbed her spit all over my dick with her small black hands, then giggled as I groaned when she rubbed it all over her face. I dropped to my knees as well and she dropped to all fours and spun away from me, thrusting her wide ass back at me. I grabbed her hip and slid the head of my fat white cock up and down her grey bush till it was slick. She begged me to let her feel it and I slid the tip inside her, pulling back and pushing in again till all 8" was buried inside her tight, hot wet pussy...
