[A4A] [A4A/AA/GM] mutual, male sub, or unusual freeuse

Looking to discuss and roleplay a freeuse setup other than a woman being freeuse for a man. Possibly a group or GM'd roleplay. The partners' relationship and freeuse arrangement is open for discussion. Even the extent/limits of freeuse (clothing/exposure, sex acts, even weird or non-sexual use of partner). I am happy to play either role, any gender. Some possible arrangements:

1. Either partner may initiate at any time and the other accepts
2. A man doesn't ask or initiate but is available for freeuse by his partner
3. A third party, such as live stream chat, decides when and how a couple has sex (this could be a group or GM'd rp)
4. One person is freeuse for anyone in a group (this may be polyamory, friends group, coworkers, the public, or some other group)
5. Everyone in a group is freeuse to one person
6. Everyone in a group is mutually freeuse to each other
7. Everyone in one group is freeuse to anyone in another group
8. Other: I'm open to discuss any freeuse or related setup

Let me know which arrangement(s) you're interested in and let's discuss

I am 18+ and all participants and characters must be 18+
