Need advice/help with safely planning out an extended session
So I’ve been playing with this sub where we share a huge love for rubber/latex. Personally, I’ve had experience from playing with a handful of subs, but I wouldn’t call myself that experienced. My sub on the other hand is older and has plenty of experience. We’ve obviously discussed limits and safe words already, but I get the feeling from our sessions is that he’s definitely into the more extreme side of things and is fine with me pushing him to his absolute limits. So far we’ve had 4 sessions with most of them lasting an hour with 1 lasting a little over 2 hours.
Recently my sub proposed that we have an extended session (about 8+ hours), but it’s something that I don’t have experience with. It is definitely something that I’ve always fantasized about, but I have some concerns as a relatively inexperienced dom over safety. The following are the things that we’ve discussed (I’ve had some experience with, but not in the context of an extended session) doing, though it’s not an exhaustive list and it has more to do with the kinks that I have more concerns with during an extended session and would like to get some feedback and advice for.
- Hogtie bondage
Just for a bit of context, bondage in our session is usually done with leather cuffs and not with rope so I’m not too concerned about potentially restricting circulation. I’ve previously put him in a hogtie with one of those hogtie harnesses and not for very long. That being said, how long could I safely keep him hogtied? This is especially a concern for me considering that he’s on the older side.
- Analplay/ fucking machines
In our previous sessions, I kept my sub plugged with a vibrating butt plug throughout our entire sessions except for when I remove it to fuck him. This time he proposed that we do the same, but for longer and with me fucking him and using a fuck machine on him. My concerns with this is a) how long can you realistically wear a plug before it starts to present potential health issues and b) how long can safely I use the fucking machine on him at a time?
- Rubber encasement/storage
My sub has a huge kink for being placed in a rubber sleepsack to be stored away for long periods of time while I’m in another room. I’ve only done this for a maximum of 20-30 minutes with him. I know that with mummification you have to keep a watchful eye out for circulation issues, but is that the same case with a bondage sleep sack (specifically with rubber in this case)? Is it a good point to release him periodically to allow him to stretch? Beyond that, I’ve already made it a point to check up on him every 20 or so minutes to allow for hydration or if needs to use the toilet and to also never leave the house with him just there (even if it sounds like a hot idea).
- Ball gag
He and I share the kink of the sub staying gagged during a session, the idea that the sub’s mouth is useless and has to be gagged when not used for sucking or worshipping. It’s a very hot idea, but I’d also like to be realistic and I can imagine that a ball gag can get quite uncomfortable to wear after a certain amount of time. My question is how long would that be before it starts to get unsafe. An alternative that we have is that he has a rubber hood that comes with lockable zippers for the eyes and mouths. Although obviously not as effective as a gag, me closing and locking his mouth zipper can be a way of “taking away” his speech.
For now that’s all of the concerns that I have with certain types of play that we would like to have during the session. Are there any other things I should be concerned with during longer sessions that I haven’t brought up? And do you guys have any suggestions/ideas on things that could be exciting during these longer sessions?
