Edit : I already found the story i was searching for. It's ''LUCIAN COMES HOME''. Still i would like to read something similar to this. I mean - boy hear sounds ( you know what sounds ) and got tricked to think it's not sex or masturbation while at the same time it will gets harder to tricking man because vibrator vibes faster or something. Lots of
ambiguous speak / texts etc. For the best ( in my opinion ) Man should be so much naive ( or should be stupid ) and the guy that use woman should do his best to expose nature of woman to a man in the story. ( it should look like they want to be caught by a man but also tries to hide it from him ) Maybe other womans also will be involved ? Sister / Mother / Wife / Daughter / Grandma / Aunt / Cousin / Woman Boss / Woman Cooworker / woman neighbour etc.
I dont know if i want the man to see woman/s naked or not. If yes then i probably preffer tricking/convincing him that its not the woman he know somehow.
I just remember that in the story was MC coming home early for his birthday and there sould be his friends and his sister but none of them was there. Then he hears strange sounds from upstairs ( it was obviously moans ) He goes there to check whats going on and sound were louder. When he was ready to open the door his sister ran from the room and slammed the door behind. She will try to not let her brother go to the room. She also moans a lot but she said its cramps and she need her brother to buy pads for her. Also she have a little sperm on lips and when bro mention that she said its just a yoghurt.
I remember that bro also hears other sound from room and when he focus he also hears bzzz ( obviously vibrator in sister pants ). When sis gets close to orgasm in front of him she probably yell at him to go to shop and when he goes downstair she ran to the room where she was fucked again. Whats more - she was pushed to door so when she gets punded doors makes sounds like they gonna fall apart.
Not so sure but maybe at one point doors will get opened for a little time and her moans were more clear at this time for her brother.
After that later in the story that for me ruined this story was bro peeping through window from outside and after that sis was about to go to the shop to buy pads for herself so he goes to the shop by bicycle as fast as he can. Sis goes shopping and he will be in her car. So he checks her phone
