Around 1968-1972 my older friend's parents gave him a subscription to Penthouse and Playboy. I would visit him and avidly read the reader forums of both. I did not realize it at the time, but a couple stories really stuck in my mind since I was already a secret Dom and sadist. I would love to find it again but can't remember the issue or whether it was Playboy or Penthouse, or one of the Forums. I am going to plagiarize the story, using my own words and expanding it with far more detail and fanasy than in the original few paragraphs. Also, the story was written by the woman in the first person but I am going to do it in the third. If you know the magazine and date please let me know.

Sarah was pissed. She had come over to console her friend Tara who was upset about how Tom had been treating her and behaving. Sarah was a strong Women's Lib proponent. She told Tara to stand up to Tom and tell him that she expected him to treat her as an equal. He should help in the kitchen, clean and not order her around. But Tara would not come out of the kitchen to face Tom. Then Tom called out, telling Tara to bring two beers. Sarah stormed out of the kitchen and started berating Tom for the way he was treating his wife. She called him a chauvinist, lazy layabout and generally insulting him.
Tom stood up, grabbed Sarah's arm and pulled her across his lap as he sat down. Sarah started struggling but Tom's friend Mark grabbed her flailing arms while Tom threw a leg over her legs and held her down. The first few thuds on her ass were more shocking than painful. Then Mark said "The skirt is muffling the strokes." Sarah suddenly felt cold air on her ass as the skirt was flipped up over her shoulders. The next smack stung. A lot. Sarah cried out and struggled but the men were too strong. After a while she stopped struggling and simply cried from the pain and humiliation.
When Tom saw she was quiet long enough he stopped the spanking and then unceremoniously pushed Sarah off his lap. She just lay there on the floor, sobbing and not moving. After a couple minutes Mark spoke again. "I think she wants to be fucked."
Sarah felt incredibly humiliated. How did he know? She was a liberated woman who had just been assaulted. Why was she not leaving in anger? But she could not move, feeling their eyes on her red and bare ass.
Tom asked "What makes you think that? She is a die heart women's libber probably incensed at being shown her weakness."
Mark laughed. "She is still laying there, and has not bothered to pull her skirt down. She's showing us her bare ass and notice how she is rubbing her thighs together. She looks wet.".
Tom said "Well, I am not going to rape her. Besides, I fucked Tara just an hour ago."
Mark laughed again and said "No rape needed. Slut, if you want more spanking and to get fucked crawl into my lap."
Feeling new waves of humiliation, Sarah got up on all fours and slid over Mark's lap. Her skirt had slipped down. Mark flipped it up and it went over her head. She did not move to uncover her head. She had an image of herself, humiliated by objectification, just an ass sticking in the air with the top half hidden, unimportant.
Mark's hand landed on her ass with a loud smack, then he squeezed the cheek. Again, smack and squeeze. "Your panties are soaking, take them off." came the order.
She reached down and slid them off as far as she could reach. Smack, and a light finger trailing up to her tailbone. Again and again, smacks and squeezes or light stroking without a pattern. When light fingers trailed over the exposed part of her pussy lips she spread her legs to give better access, and could not believe that she was doing that. Mark laughed again, and the next smack landed right on her pussy lips. Sarah jerked with surprise, then settled back for the next stroke.
