CIMWS have only had this with 1 girl. It was amazing.
COF I have been lucky to have had it a few times. Had it with a few girls at MsSILQUE escorts. Also at one of the latin houses in Croydon with a Mexican girl who I paid extra. They were amazing experiences.
I think one of the things that all thge girls told me was to avoid the eyes as you could get infections and it hurts.
There were couple of times I came partially on a couple of girls faces as spurted all over while doing Spanish, one was with Natsu.
