Nothing was more enjoyable to Marianne than coming home after a busy office day and entrusting herself to the tender hands of Mona for a relaxing wellness ritual. The young chambermaid always knew exactly what her lady needed to relieve stress. Photo from the 1970s #eroticart #sapphiclove #lesbian

Ilonka was very satisfied with her apprentice. Usually new girls refrained from hitting hard enough in the beginning, but Zita's strokes already left beautiful welts on her client's buttocks. She had talent for sure. Illustration by Alex Székely (1950s) #eroticart #bdsm #sexworker #caning

There were times when Gina had struggled with the fact that she didn't have Twiggy's body. And she had hated all the gross remarks about her large breasts by her classmates as a teen. She was happy that these days were over, and shame had left her. Photo from the 1960s #nudist #FKK #bodypositivity

Melanie loved to visit her grandparents during the college summer break. Helping in the fields and the garden was fun, but what Melanie enjoyed most as a nudist was that nobody bothered about her sitting naked on the front porch of the remote farm. Photo from the 1960s #nudist #FKK #nudistfamily

Growing up on a farm, Nancy was already familiar with the ways animals breed. Watching the mating rituals between her mom and their farmhand was much more fascinating, though. And she had plenty of opportunities to study it. Illustration by Louis Berthomme Saint-André (1933) #eroticart #voyeurism

"12 pm, Westminster Bridge - dare?" read the note in Lizzy's mailbox. She knew the handwriting. Tess was such a crazy bitch, but this was by far her most outrageous idea. "Fuck it", Lizzy mumbled. She'd never let her friend down. Photo from the 1960s #eroticart #streaking #exhibitionist

"Hi Josh! It's Andy... I am calling because my parents are off for the weekend. I thought maybe you'd like to come over. We could hang out together. Having some fun... Like last time." Photo from the 1970s #eroticart #gaysex #boys

"Listen, Mr Teddy Bear! You know that a gentleman never tells, right? My daughter doesn't need to know she isn't the only one who loves grinding on your nose. Do we have an agreement?" Photo from the 1960s #eroticart #masturbation #familyfun

Sam had been so afraid about revealing her secret to her schoolyard crush Naomi. Her "so what?" reaction came as a shock to Sam, just as the black girl's firm grip on her girlcock and two of her fingers shoving up Sam's ass. Illustration by Kimberly Wilder #eroticart #trans #girlcock #queerlove

It's #SinfulSundayagain: Sister Agatha often heard other nuns of her convent torturing themselves about having become guilty of sins like pride, envy or sloth. Of cause, noone was infallible, but she preferred committing sins that were actually fun. Photo from the c. 1910 #eroticart #naughtynun

Lady Desdemona was satisfied to see how the process of Andy's submission was progressing rapidly. Within a month he had transformed from a macho asshole to an obedient toy. Soon his anus would be trained enough to be used by her gay friends. Photo from the 1970s #eroticart #bdsm #femdom #strapon

They called her "Backseat Betty" for a reason. Dr Sinner's limousine was quite an upgrade after her classmates' small cars she had seen so far. It not only proved to be more suited for having fun, her teacher was also a much better lover than the boys. Photo from the 1960s #eroticart #carsex

Being a good and caring mother, Martina had long suspected that her son was into boys. Catching Tim passionately sucking off his friend Dan, when she entered his room one summer day, dispelled any doubt. She had to admit it was a hot sight. Illustration by Harry Bush #eroticart #gaysex #fellatio

Angela lifted her lingerie and proudly displayed the delights of her pregnant body to her husband. "Look at my big round belly. Touch my enlarged tits. I might be pregnant, but that doesn't mean I can do without sex. Quite the opposite." Photo from the 1970s #eroticart #pregnant #sexpositivemom

Annabelle's rigger was so good in tying her up in a way that even the slightest movement of her body would result in the rope, which was parting her labia, rubbing and putting intense pressure on her clit, until she was moaning in agony. Photo from the 1980s #eroticart #shibari #kinbaku #bdsm

One of the things Ricarda loved most about her nude hikes in the woods was the liberating feeling of being able to pee everywhere she wanted without having to stand in a long queue with a full bladder in front of a ladies' room. Photo from the 1970s #nudist #FKK #peeing

For years Madame Glouton didn't dare to tell her husband about her frustrations about his underwhelming equipment. When she finally did, he fortunately didn't take it as an attack on his masculinity, but came up with very innovative solutions. Illustration by André Collot (1930) #eroticart #dildo

Jack met with his best buddies at the gym every Friday night. They took it easy during the workout, since the main action was happening after the training in the locker room, anyway. Rick and Stan always had some yummy protein shakes for him. Photo from the 1970s #eroticart #gaysex #threesome

Astrid's thirst for knowledge was insatiable, but she always preferred field research over purely theoretical knowledge. So when sex ed was on her curriculum, she simply asked her mom if she and her boyfriend would provide her with some insights. Photo from the 1970s #eroticart #sexed #fellatio

Valerie had often imagined having sex with her friends when she masturbated, but only when she showered together with Hannah and Phil after a sensual body painting session, her dreams finally came true. Photo from the 1970s #eroticart #threesome #bisexual
