Hal and I were busy fucking Karen, him in her mouth and me in her pussy, when there was a knock on the dorm room door. “Shit!” Hal said. “Who the fuck is that?”

His words must have been loud enough to be heard outside. “It’s Karen’s mother,” came a voice through the door. “I believe you have my daughter in there.”

My first instinct was to jump out the window. My second was to get the girl out of sight, or at least cover her up. But I didn’t have a chance. Before I could move the doorknob turned and the door swung open. I couldn’t believe Hal had left it unlocked. On the other hand, I could believe it. Hal was like that.

“Oh, Christ!” Karen said, raising her head from Hal’s crotch. “Don’t you ever give up, Irene?”

The woman who stepped into the room was probably in her late 30s, but she looked at least 10 years younger. She was taller than her daughter, and her body was thinner, though it filled out in the right places. Her hair was lighter, a lustrous brown, and shorter. Her face was unlined and quite attractive. She was wearing a green print dress which showed off her figure and stopped at mid-thigh. It might have seemed too young for her if she had looked her age, but as I say, she didn’t.

In great confusion, I hastily pulled out of Karen’s voluptuous body and scrambled for my trousers, which I somehow got on, while Hal did his best to cover himself with the bedsheet. The woman shut the door behind her as she came in. She didn’t seem a bit surprised to find her daughter naked on a bed, obviously in the process of having sex with two naked guys. She nodded once, as if she had been expecting to see exactly what she saw. The expression on her face was one of mild annoyance.

“So you’re at it again, you slut,” she said to the girl. She glanced at Hal, then at me. “I hope you boys have been having fun with her,” she said. “It seems that’s all she’s good for.”

“What do you want, Irene?” Karen said angrily. “You can’t control me anymore, you know. I’m over 18 now. So get the fuck out of here, okay?”

The woman gave a brief laugh. “Control you?” she said derisively. “When could I ever do that?” She glanced at me again. “Do you know what a slut this girl is?” she asked. “Oh, but of course you do. Well, playtime is over, kiddies. I’ll be taking her back now.”

“The hell you will,” Karen said. “And look who’s talking about being a slut. Where do you think I got it from, Mother?”

The woman ignored that. “Only two boys, Karen?” she inquired. “I should think you’d be into gang bangs by now.”

“It’s a slow day,” Karen replied curtly. “But these guys are not bad. You want to try them out, Mom?”

“Oh, darling,” Irene said. “If I did that it would spoil them for you forever. They’d never be satisfied with you again.”

Karen snorted. “I think you’re just jealous, Mom,” she said.

“Jealous?” her mother said. “Of you?” She laughed. “You may be a slut, but you’re still an amateur, darling. I can fuck rings around you any day. You think just because you’re young and juicy, that makes you sexy? Oh, I know you’ve had a lot of experience in your short life, but you still have a hell of a lot to learn. And besides, my body is still every bit as good as yours, if not better.”

The girl made a derisive noise. Irene glared at her, then turned to Hal and me. Facing halfway between us, she put her hands on her hips, standing very straight, taking a deep breath and holding her head high. Her dress pulled tight against her breasts and clung nicely to the rest of her curves.

“What do you say, boys?” she said. “Is this body as good as my slut daughter’s? Tell the truth now.”

Now Hal spoke up from the bed. “Well, it looks good, all right,” he said. “But we can’t really compare. I mean, she’s naked, you know?”

“Yes, I can see that,” Irene said dryly. “It seems to be her condition of preference these days.” She sighed. “Oh, very well. If that’s what it will take to convince you.” She then moved to where I was standing and turned her back to me. “Would you unzip my dress, please?” she said.

I was stunned, and for a moment I did nothing. “Oh, for Christ sake, Irene,” Karen said. “Must you? Really?”

“What’s the matter, Karen?” her mother replied. “Afraid of a little competition, are we? Young man,” she went on, addressing me, “I asked you to unzip my dress. If you don’t wish to comply, I’m sure your friend over there wouldn’t mind.”

“Hell, no,” Hal said, grinning. “Bring it over, honey.”

“I’ll do it,” I said. I was kind of surprised to hear myself say it. I knew this might lead to a lot of trouble. But I had to admit I was kind of excited at the thought of seeing this woman’s body, especially alongside that of her naked daughter. I raised my hands to the back of her neck, undid the little clasp there, then pulled the zipper down to her waist, which was as far as it went.

“Thank you,” Irene said. She stepped away and turned around so that she was facing both of us again. Then she slipped the top of the dress off her shoulders and, without pausing, wiggled the garment down over her hips and let it fall. She stepped out of it and stood there in her white bra and panties, looking from Hal to me and back again as we gazed at her in obvious admiration. “Not bad, huh?” she said, smiling.

It wasn’t bad at all. Her figure was every bit as good as it had looked in the dress, if not better. Her flesh was smooth and unblemished, her legs were shapely all the way up, her breasts stood out proudly. I could just make out the shapes of her nipples thrusting against the clinging bra.

“Jesus, don’t stop!” Hal said then.

“All right, that’s enough, Mother!” Karen exclaimed. “Go peddle it on the street or something. We’re busy here.”

“I think you’re outvoted, Karen,” Irene said. “Isn’t she, boys?”

“Damn right,” Hal said. Irene looked at me. I nodded.

“You see?” she said. And with that she reached behind her and unhooked her bra, then pulled it off. Again she struck a pose for us, sticking out her chest. “So?” she demanded. “Are these boobs every bit as good as this silly creature’s or what?”

And in their own way, they certainly were. They were not as large and rounded as Karen’s, but they were plenty big enough for her slimmer figure, and they didn’t sag at all; they were high and firm and seemed to burst with life, with long red nipples which, as I had suspected, were fully erect. For a moment I wondered if those breasts were real, and Irene seemed to read my mind.

“All natural,” she said proudly. “Never had a lick of surgery in my life. Want to feel them?

I did. I couldn’t stop myself. I moved to her and put my hands on them. Irene moaned. They felt natural all right. They felt just fine. I felt them for a while, as she stood there smiling at me. Then Hal spoke up. “Hey, what about me? Don’t I get a feel too?”

“Why not?” Irene said. “Come on over.”

“Jesus Christ,” Karen said disgustedly. But Hal didn’t hesitate. He threw back the bedsheet and got up. His cock was very hard, and he didn’t try to hide it. Irene didn’t seem a bit surprised. I saw her eyeing him with appreciation as he ambled over to us. He put his arms around her body from behind, his hands pushing mine out of the way as he wrapped them around her breasts. She gave another little moan and pressed her body back against his. She didn’t make any protest as I bent and pulled down her panties. Her pussy was shaved bare, unlike her daughter’s. I wanted to kiss it, but I just straightened up again.

“Yeah, not bad,” Hal said. “Not as much of them as Karen’s got, but pretty nice.” His fingers tightened around them then, squeezing.

“Hey!” Irene said sharply, pulling away from him. “Easy there, guy. I don’t know about my slutty daughter here, but I don’t like it rough.” She turned to me then. “How about you?” she said. “I bet you can do better.”

I didn’t know what to do, so I did the only thing I could think of. I kissed her. As soon as my mouth met hers she came up against me, her arms went around me and her mouth opened under mine. Her tongue slid between my lips, and I met it with mine. I put my arms around her and slid my hands down over her ass as she moaned into my mouth. My cock was harder than ever in my hastily-donned pants, and she felt it and squirmed against it. I could have kissed her forever, but after a while she pulled slowly away. She was panting slightly. So was I.

“Good boy,” she said, patting me as if I was a dog. “Now why don’t you take those pants off while I take care of this big brute right here.” She reached back to stroke Hal’s still erect cock, then turned around and went down to her knees in front of him.

“Jesus!” Karen said. “You’re pathetic, Mother. No wonder Daddy threw you out.”

“I give better blowjobs than she does, too,” Irene said. “You be the judge.” And with that she took Hal’s very large cock into her mouth. She took it slowly but she took it all the way, sliding her lips down over the length of it and just never stopping until she had the whole thing in her mouth. I don’t know how she did it, but she never even gagged. Then Hal was moaning and gasping as that mouth began to move up and down. Meanwhile I did as she’d said and took my pants off.

“Damn it, Jim!” Karen said, almost pleadingly. “Don’t do this. I’m younger and better than her, and you know I’ll do anything you want.”

Irene took her mouth off Hal’s dick. “Oh, stop it, you silly little bitch,” she said. “The boy obviously wants to stick that thing into me, not you. And who could blame him? Come on, Jim. Don’t be shy.” And she raised herself on her knees and spread them apart, crouching now on knees and elbows, her ass sticking up and her pussy on display. Then she lowered her mouth to Hal’s dick again.

Karen let out a wail as I got down behind her mother and lined my cock up with her pussy. She was already nice and juicy, and she moaned around Hal’s prick as I pushed into her. She pushed back, and within seconds I was all the way inside her. I was surprised at how tight she was, and I wanted to stay there for a few moments to savor the sensation, but Irene started moving back and forth, fucking me with a slow rhythmic motion while her head moved up and down on Hal’s cock. God, she was good! Her hips twisted a little as we pumped at each other, and soon all three of us were moaning and gasping. I could hear Karen saying something in the background, but I was too busy enjoying myself to listen.

And then there was a knock on the door.
