I enjoy watching this and with the "right" lover I find it extremely pleasurable. I find the feeling of gagging quite thrilling and the saliva quite erotic. By "right" I refer to the chemistry between us and genuine attraction. By watching I mean porn and on occasion as a voyeur and maybe watching myself in the mirror
I've only had the opportunity once but with a w/l who was really into it and encouraged me and it was a feeling like no other especially as she was really getting off on it while her friend watched. I 'd definitely try it again with the right person.
I would love to experience this (giving) as it is something I enjoy watching. Dallas, you had a someone watching you while you experienced this....that ticks a few boxes fro sure.
