Greetings to the forum and its inhabitants. I’ve been sharing a common topic with you for a long time, but I haven’t written before... Which is strange, because there’s a lot of interesting stuff.
Many describe how and what they had, I just read and was happy for them, but today I decided to take a step myself.
Forum, I ask for help: How to bring my sister to the topic of sex or at least... well, let's call it “helping each other”?
I won’t reveal my age, but my sister is the youngest, her figure is not particularly outstanding, but pleasant.
Something interesting... Not long ago I started studying the topic of medical massage, purely for myself, well, and to practice it, I asked for help. Consent has been obtained and at times she asks for a massage. I deliberately do not cross the line, and, by nature, I try to do everything professionally and strictly within the norm.
But... I'm ready to move on.
Just don’t mess up anywhere... P.S.: Well, I’ll slowly start typing 70 messages)
