Betty was one of my work colleagues. She was about 5’ 4” and was overweight just the way I like my women. Her breasts were huge and needed those huge bras to hold them, and no matter what she wore, you couldn’t help but notice them. Her back curved into the top of her massive ass that must have been twice my width, and her legs were not out of shape, just much larger, thicker, and she always wore stockings, or at least I hoped so.

It was my second week there, and I was still getting to know everyone. I must have only said three words to Betty since I started. Ann was one of the other girls who worked there, and she was one of the fabulous girls you see about town. She presumed I’d be all over her, and when it was clear I wasn’t, she flirted with me to try and win my attention, even though I knew once I made an approach, she’d reject me or make me beg, which I never do.

Betty was bent over trying to pull some jammed paper from the copy machine, and I was staring at her ass in her stretched skirt, trying to see if I could spot the straps from her stockings. I knew if I could, I’d be horny for the day, and she wouldn’t have a clue.

In a trance, I was too slow to avoid being couth when she quickly turned her head and saw me staring at her ass.

“OK, so I have a fat ass, big fucking deal. We can’t all be skinny bitches,” and she shot a look over at Ann, who hadn’t noticed while she said it.

“I was ... uh, I mean, I was uh...” I stumbled, my mind a blank. “It’s amazing,” I said like an idiot.

“Well, I’d prefer if you didn’t make fun of me if that’s alright with you,” she hissed at me and walked off.

Holy shit, what an asshole I was. I was dumbstruck and could only now find the words I should have said, but fuck it, it was too late.

A week later, here I was again staring at the amazing ass as it was once again bent over. This time, it was her own desk as she leaned over still on the phone and tried to grab a pen. The fabric was pulled tight, of course, but this time I could clearly see the thick strap of her suspender belt running across her left ass cheek. That was it for me for the whole afternoon. I couldn’t get that image out of my mind, and my cock was half hard the day through.

Later, the boss told Betty she had to finish his report by the next morning, and it was now 17:30. She complained but said she’d stay late. When everyone had gone, I busied myself until there was just Betty and me. I knew she was 42 and unmarried, but that was it. I hadn’t seen any boyfriend around the office or picked her up. She stood up and walked over to the filing cabinet, and low and behold, she bent over to open the bottom draw. My cock sprang up at the sight.

Now I could see her ass and the two straps. They looked like they were dug into her skin. I moved over to her quietly and stood just behind her. She sensed me there and looked back and up. “Yes?”

I didn’t say anything but placed my hands on her ass and moved my hips against hers. She reacted fast, pushing my hands away and standing up. She smacked me hard on the face. “How dare you feel me up, you bastard!” she screamed.

“Wait! Listen, I can explain,” I said. “It’s just that you’re so sexy, and when I saw...” I stopped and stared at her. She looked pissed off, with her hands on her hips and her tits pushed out. It wasn’t helping me.

“I asked you to stop making fun of me. I’ll have to report you for this,” she was still pissed.

“I’m not making fun of you. I really think you’re sexy,” I said, hoping to calm her down a little.

She eyed me up and down, and when she saw my pants and the shape of my cock pushing against the fabric, she looked up at me and gave me a half smile. “Oh really? We’ll see about that. Follow me.” She marched away towards the boss’s empty office. I followed her in and waited to see what she had in mind.

“OK, so by watching me bend over, you get a hard-on?” she asked, looking down at my cock, which was now receding.

“Well, you have such a nice big ass, it does. Sorry.”

She just smiled.

“And, well, when I saw you were wearing stockings, I was out of my mind all day,” I continued.

Grabbing each side of her skirt, she yanked it up over her hips. She was wearing black stockings with what looked like a black pair of panties, but her belly was swelling over them, hiding the view. “There you have me in the flesh. Still horny?” she smirked as if I’d find the sight disgusting.

I smiled and opened my pants, pulling my shorts down and letting my hard cock spring into view. She stared at it open-mouthed. “Well, yes! You look even hornier now, I guess.”

“Would you turn around for me?” I asked.

She turned around and showed me her massive ass. Her panties were lodged in between the cheeks of her ass, and the straps were pulled across just like I had imagined.

“Would you bend over for me?” I asked, not expecting her to do it, but she did, bending right over until she could almost touch the floor. I was behind her for a second, my hands running greedily over her smooth, ample ass and my cock butting against her.

Pulling her panties swiftly out of the way, I guided my cock between her ass cheeks. She jerked forward, trying to get away from me, and fell across the top of the boss’s desk. I sprang on her, pulling her panties away again and jabbing my cock at the crack between her legs.

“NO! DON’T! I can’t do this!” she said, turning her head to look back at me. But I had located the entrance and couldn’t stop myself. I pushed forward and felt myself enter her tight pussy.

She screamed as the rest of my cock slid home. “No! Please stop, you can’t! NO, PLEASE!” she pleaded. But I was still trying to get a grip on her ass and wasn’t listening.

When I pulled my shaft out to begin fucking her in earnest, I saw it was wedged tightly up her asshole and not her pussy. This was why she was trashing about. There was nothing for it, so I rammed my cock back in and started fucking her back-hole with long, smooth strokes.

She lay there limp as I built up a good rhythm. I managed to move one of her legs up onto the desk, stretching her ass-cheeks wide and opening the way for me to fuck her properly.

“Oh Betty, your ass is so tight. I’ve wanted to do this since the first time I saw you.” She still said nothing. Her ass was wet now, and my cock was sliding in and out using the grease from her own ass. She was not in pain, and I began to feel her pushing back a little.

With my hand on the small of her back, I pulled my cock out and moved it down to her pussy below. I shoved it right up to my balls and fucked her frantically like that for ten or so strokes when she started coming hard. She let out a cry as she did, and her pussy flooded with juice, drenching my cock.

I ripped her panties off her and grabbed her fat as I pounded into her, watching my cock push it way in and out of her slack cunt. “Oh yes! Fuck me, boy, fuck me harder!” she screamed. She was coming now, over and over again, and I didn’t let up the pace.” Oh YES! Fuck me! Yes, I’m coming. Fuck me hard!” I was digging my fingers into her fat ass and fucking her harder the more she talked.

“Your pussy is so hot, slut!” I moaned.

“Yes! Call me a slut, fuck me like a slut!” she commanded, and pulling my cock out, I once again shoved it up her ass. She let out a loud grunt as she took my shaft up her ass. “Fuck my slutty ass, you bastard, harder!”

I was loving this and just pounded the shit out of her. I grunted, “Pull open your ass cheeks, whore, so I can see your fat, slutty ass getting reamed!”

To which she reached around and stretched her ass wide, showing me her puckered hole with my hard shaft sliding in and out. She was wet from ass to pussy, and I was able to change holes every couple of minutes, keeping her coming and coming.

“I want to suck your cock. Please let me suck you off,” she managed. “I want you to shoot off in my mouth.”

I pulled out and moved over beside her on the sofa and offered her my cock. It was wet and slimy from cunt and ass, and she engulfed my whole cock in one go. Man, she was so horny, she was sucking and pumping my cock. I was going to come soon. “You want my spunk, whore?” I was watching her mouth bob up and down on my meat. She stopped and looked up at me whilst pumping my cock with her hand and said, “Yes, that’s what sluts do, right? Shoot your spunk in my mouth. I want to swallow it all.” And she attacked my cock again with gusto.

Then it came. I shot load after load into her mouth. She gagged with surprise at the first spurt but quickly managed to pump the rest onto her face. Holding my cock herself, she aimed it at her eyes and hair before sucking it back into her mouth and sucking it dry.

We lay in a heap for 10 minutes, and she got up then and stayed in the toilets until I left the building. Next time I got to see her tits, I can’t believe I didn’t yet, having done her good and even fucked her ass.

The next day, she acted cool as if nothing had happened, ignoring me as always and working hard. Her shirt was white and see-through, and she wore a navy skirt that was tight around her ass. At 11:30, I saw her go into the supply closet and moved in after her. I closed the door and stood with my back to it. She looked at me calmly and carried on getting what she wanted from the shelves. Then, bending from the hips and keeping her legs straight, she reached down for the bottom shelf, and I was off. Behind her, I grinned, my hips into hers, holding her big hips in both hands.

She jumped up straight and turned around. “Not here, you idiot. Someone will come in.”

“You’re not leaving until I at least see your tits, girl, so open your shirt and let me see,” I ordered.

“I’ll show you, but quickly and then get out, OK?” She opened her buttons and pulled her shirt open, her tits wedged into her bra, which was one of those huge old-style ones with lace.

“The bra, quickly!” I said, staring as I waited to see her massive tits before me. Instead, she reached down and caught the underside of each cup and pulled up, making her two tits flop and swing free. They were fucking huge, her nipples were large and brown with rings around them the size of saucers. I reached up quickly and garbed on in each hand, digging my fingers into the flesh.

“Right, that’s it, now go,” she said as she began pulling her bra back over her tits.

Catching her off balance, I spun her around and pushed her roughly up against the shelves, her tits still hanging out. Before she could say a word, I pulled her skirt up, which was hard as it was so tight, but managed and saw she was wearing a white pair of panties and stockings.

“Stop it! Someone will come in,” she pushed back with force, but I held my ground, grabbing her panties and ripping them from her.

I got my cock out, and after a couple of attempts, it slid up her cunt. She let out a low moan despite herself as I worked my cock into her pussy. It was a fast, frantic fuck, and I was thinking of me only here as I pounded her hard from behind. I reached around to feel her massive tits as they flopped about from the fucking she was getting.

Before coming, I pulled out of her and turned her around. Taking her by the hair, I pulled her face down to my cock against some resistance until she understood she was not getting away until she sucked me. Once she knew she had no choice in the matter, she opened her mouth and started sucking on me.

She was bent over from the waist, but I wanted to see those tits. “Kneel down, slut, I can’t see your tits,” I commanded. She fell to her knees before me. Now I could see her big tits hanging there in front of me.

“Now look up at me while you suck me, baby.”

She started lapping at my cock and sucking. This was really nice. I was about to come and take my cock in hand. I jacked off over her face, still holding her hair until with a grunt, I emptied my balls onto her face and tits. I aimed most of it at her tits, which were covered with my spunk.

Zipping up, I looked down at her and smiled. “You’re my slut now, girl, aren’t you. You better get used to it, or it’ll be costly in panties,” I laughed and left the closet, leaving her to clean herself up.

I still knew nothing about Betty except she was sexy as hell and she made me horny on sight. Friday night came along, and it had been a week since I last had her, and I was horny again. So when no one was about, I asked her if she fancied a drink somewhere. “Why don’t you come around to my place and have dinner?” she replied, writhing down her address and handing it to me.

“Fine, I’ll see you there at 20:00,” I said and returned to my desk.
