Pregnant wife with husband decide to rent a woman that dominate and humiliate. She will live with them till wife gave birth. The woman will be respectfull to a husband and wont humiliate him ( there will be something that could be taken as humiliating thing towards him but he likes it etc )
Sometimes wife will be taken for a night or more to spend it with a woman in her room. Woman also will visit husband at night ( sometimes will take wife with her sometimes she will wear sexy clothes ... or even will be naked and stuffed every hole with a vibrators ) Sometimes stranger woman will squirt on sleeping husband for ''marking him as her'' in front of wife. Woman will record wife humiliation and take photos. Sometimes these video will be playin in house at loud volume.
Somehow i think it will be nice to also include wife's mom in this story. Starting with maybe some fuck while she's on phone ? and when she decide to visit the couple will get blackmailed and forced to watch her daughter humiliation ? Maybe she also gets aroused by this and will help them ?
Time passed
Wife born a son
and husband is not with her anymore ( Dead ? Divorce ? up to you )
When son hit the ''legal'' age she called the women from the past. She wont be working alone anymore ... now she works in pair with young girl that have innocent look and is kinda shy. She also have a secret - Big Dick !. Shes a different person at sex. She dont know ''slow'' and when she starts she dont know how to stop. Dont care if someone she fucks is crying or not, she also dont care if someone she fucks got caught or not.
They visit the wife from the past and greet the son. Womans will slowly works toward ''changing'' son to someone else.
Mom will get fucked at risky situation ( son is near , behind a corner ... something like that ).
I think for the story it would be also good if son will have a room near mom's ( his room , wall , mother room [ hope you get it bcs my english is bad ] )
At some point they together would think they should introduce son to sex / porn. So at night they will watch together old record of mother humiliation (she wears mask).
Video will be at loud volume.( maybe later they will do something like fucking his mother, he arrives at home from school but he just caught the woman watching porn [ maybe another old records ? ] ) Girl with dick took mother by a surprise and will pound her ass and says to her ''match your moans with those in video if you dont wanna be found by son'' The other woman sloswly will corrupt son to take dick out and stroke it. He will asks if this is okay ( maybe would have other asks as well ? ) Mother will be forced to answer it while bein fucked. At some point he will be so focused on watching video and stroke the dick so he dont even know what the woman was talking to him ALSO he will see blurried reflection on the tv. Many thoughts will rush in his head so it will ''paralyze'' him for this moment. The woman near him will end the job by taking his dick and stroke it till he finish.
After some time they will asks son about his woman prefferences while his mother is alongside them / held by them. Nipple type , Boobs size and if he likes bald pussy or hairy one. When he answers that he likes hairy but not with a bush down there , just trimmed they will laugh. Woman will said ''now your mom needs to grow hair there ( showing mothers place to son ) it was like for 3 seconds. but it was long enough for son to recognize tattoo his mom had. It makes his dick hard as rock in a second. Womens laugh and the one with pussy said '' if this makes your dick react like that then what will he do when i do this'' and with agile movement she will be showing pussy and boobs to him ( the stranger woman not the mom) . Son will shoot a sperm and all this situation will make him faint just at the same time he shoots sperm. Not sure if he hears it right but the last thing when he was falling he hears '' now your mother needs to lick your sperm ... '' And when he faints they will bang his mom and at some point thet will takes his pants turns right to left and makes him wear it in head. Mom needs to lick sperm from those pants while fucked at the same time. After all woman will take pants out of mother pussy ( she will be stuffed all this time ) and now this wet panties by moms juice will be wearing son while son's panties now will be stuffed inside mom.
Woman will take care of son while he's unconscious. He will ''wake up'' with her in his room. She will said that hes so cute yet so innocent so she have 2 gifts for him. ( 1st will be her tricking him that he wear her panties [ maybe she will show that she doesnt have any ] second gift will be hole in wall to spy on mom ). At the same time mom will be told to masturbate in her room and talk about son ( tricked to do it - she will think that her son still sleep but son will wake up early from faint bcs woman wakes him up by smelling salts )
also i would like the grandma to be part of this story too. Also maybe son's friends will use the mother as well (not just the males but girls too?) ? maybe once they will use the hole from son room ( tolded by woman ) and mom will pretend that its her son ? It will be nice if others will be using his mom as well. and maybe some records will be used by teacher in a lesson where he/she learn students about sex etc. entire class will comment how a great MILF she is ( on the video ) even girls in class will love it and be horny. Teacher also could encourage students to masturbate bcs its unhealthy to hold it in while dick or pussy feels horny.
Also i think it will be nice if best looking girl in school will be his GF BUT she will work on him to dominate him / humiliate him.
Edit - Additional ideas for this story :
1. Bathroom sex in shower which glass is like venetian mirror and soundproof ( from inside will be visible who and what is outside but someone from outside cant see whats inside )
Good for fcking mom not really in front of son but to make her feel like this.
Maybe:
- At some point shower could be a little open by a girl with dick that fucks mom just enough to son hear something
- At some point mom could be forced to stick head out of shower while being fucked at the same time and talk with son / asks for things.
- At some point glass could be changed to ''normal'' and mother could be tricked to think that its still venetian mirror.
2. Party in swimming pool where both son and mom will be used by others and pretends thats nothing happens to them.
Maybe at some point one of party member would play ''moans'' sounds from speaker and things for son and mom will be getting tough to not make a sound ( they will do a sound ... lot of ) and from time to time party members will make mom see son having fun without son knowing and same to son - they will make son see mom having fun and mom wont know.
3. Kinda like previous idea but in addition mom will be taken to home and son will be taken out of swimming pool and used in grass. At some point one of old ladies in the party will ride son mouth while mom will be fucked in the balcony seeing all this. While son eats ladies they will squirt on his body so at some point mom will be forced to squirt from the balcony on son ( he wont know )
4. Just something to add between sex stuff
maybe someone will squirt / shoot sperm on food and someone else will eat it ?
5. a special party made by old ladies where young blindfolded guy is used and mom will be invited at some point and recognize the son. Maybe ladies will blindfold her to ''feel more'' and then son will get mouth stuffed by something and someone will remove blindfold. Maybe should be blackmailed to continue till he shoots twice ( maybe less maybe more ... maybe even something else ? )
6. What if ladies will make mom sleep with son every night and they will use one of them every night. Maybe even sleeping pills will be nice addition too for more ''hardcore'' things. In the end those pills could be replaced by placebo.
7. What if son will be tricked / used by a girl with dick so he ends up doing things she want and be fucked by her to get special video ( in every video will be mom )
Also i think it will be so nice to kinda make mom pregnant again by son but not literally by fucking. Maybe when he shoots it somewhere else womans will collect it and put it inside mom's pussy ? When she reach ''pregnant'' state then others males will be able to cum in her pussy as well.
