Unfortunately don’t remember lots from this story but i will try to give as much info as possible.
I think i found it on literotica!
The story was several parts. it’s about a guy and i think his roomate or friend. The friend finds out he likes to dress up as a girl and takes this information to blackmail him.
During the story he is coerced to suck his friends cock at a party in an adjacent room. In a later part of the story he is getting picked up to be humiliated by his friend. A girl is also in the car, the guy is afraid about his friend telling this girl about him sucking his cock. When they arrive at some place the guy is forced to suck his friends cock infront of the girl. The girl tells him something like “i heard you might like to wear these while sucking” and gives him her panties(could have been yellow?) to put on. He pleads to his friend but his friend forces him to put the panties on and suck his cock!
Please help me find this!
