Thought of another one. Breastplay or anything to do with breasts. I could probably write a whole book describing breasts and their beauty, not just sexually but just in general.
Father/daughter romance that includes both SFW and NSFW, I could talk about it all day with like-minded penpals. Specifically 'Dad/Father' and not 'Daddy'.
Forbidden romance. Usually on the lighter side, like teacher x student, young x old, rich x poor. Things not really wrong, just more frowned upon by society.
This is highly specific, but lamia girls coiling their snake tails/halves around my character. Whether it's something gentle like for warmth in the morning or something a bit more possessive such as making sure my character can't get away even if they wanted to
I enjoy a lot of transformation elements in my roleplay. What is happening to the character? How are they responding to this change? Have they desired it? Writing in coordination with my partner makes it even more fun for the both of us. I want us to both enjoy it. I donβt want it to be one-sided.
