As described in my previous posts, me and my gf happened to hear a good friend (girl) of ours masturbate at night.
My gf actually heard her multiple times.
And we enjoyed it.
There are more details in the previous posts.
Time passed by, we (me and my gf) talked about it, I came up with the idea that we should tell her everything, my gf agreed, but we never found a good time to do so.
I did not insist any further, because I did not want to seem obsessed about it, but recently we discussed about sex and other sexual activities on our way back to the collage, by train.
in that moment, my gf wanted to start telling her, but hesitated, saying afterwards that it was not the right place to tell her that and I agree with her.
Any advice regarding the situation at hand? I am open for both comments and PMs, if you feel like talking about it.
