I don't pretend to understand every fetish but if it works for someone then it's worth considering.When in college I would rent a hotel room to have sex with my gf. She explained her fantasy/ fetish to me so I went along with it even though it took a couple of hours .She wanted to be fully clothed and pretended to be in Bondage. First standing ...then in bed.She wanted me to grope her body stroking , massaging and poking at her privates , her ass and breasts through her clothing.After about half an hour of this I would lower her jeans and prod , squeeze and poke ( with fingers , tongue and penis ) at her asshole and vagina though her panties. Same with her t shirt which I would take off and fondle her breasts though her bra.After the longest time I would show her the jar of Vaseline . Then finally I would take her bra off and inch her panties off and ..well you know the rest of the story.So all this groping with clothes on was quite a turn on for her and she wanted it to last at least an hour . I didn't quite understand it at the time. It was her favorite foreplay.Does anyone else like this type of foreplay ?
