We've been married over 20 years, and I've mentioned to my wife a couple times I wanted to do messy play. She never seemed interested. A few months ago, she told me it was her fantasy to have sex in the garage. Not sure what triggered that, but I'm down. We did it.
After that encounter, she asked me what my fantasy was. I told her messy sex, she looked at me strange, but countered with, "that might be fun as long as anything that goes in my vagina won't cause an infection"
So, after a few weeks I got frisky and took a risk. I ordered some slime mix from messy supplies. AFTER I ordered it, I mentioned casually, "remember the conversation we had after we had sex in the garage?" (She didn't)
"Well, you said messy sex could be fun so I bought something." "What did you get" "I bought some slime that says it wont stain hair, as long as it isn't bleach blonde (my wife has beautiful auburn hair), won't stain clothes as long as they aren't white, and will go down the drain if we water it down. I couldn't find anything about vaginal safety, so we will just keep it out of that area" (I'm ok with that, as long as I have access to her hair, her beautiful face, her breasts and her sweet ass)
She giggled at me and said, as long as we cover the furniture in plastic.
Guys, I am SO PUMPED!!!
The package should arrive here late next week or the week after. I got five different colors. I'm thinking for the first time I'm just going to mix one slime, should yield 3.5 gallons. I'm going to tell her to pour it all on me and then we can make love in it.
I figure this is a good way to introduce her to it. She can see me getting to be a good sport about it, I still get to get on top of her and goop her all up, and then (hopefully) she'll be up to getting slimed the next time.
Any advice for a long time lurker, first time doer?
Well, first of all, congrats! Great to hear you and your wife are exploring each other's wants/needs/desires.
Now - You are likely standing at a great fork in the road! Actually, it is most like the devil's trident!
One one fork, you can make this totally YOUR fantasy. The benefit is that you get everything to play out the way you want and you have a fond memory for a lifetime...wow that night I got to do exactly what I wanted with my beautiful wife!! The down side is that if she freaks out at all or decides it's not for her or decides she didn't like it in any way - she will likely never, ever explore any more with you. But you still get to keep your 'night of a lifetime' memory.
On another fork, you can go out of your way to make sure SHE is comfortable and accepting, and see how things progress. Be attendant to her needs and wants, try to gauge and attend to her reactions, etc. Of course, you likely won't enjoy things as much - playing half activities director, half mental health coach and half psychic to gauge mental state. This probably has the highest possibility she might do more in the future and expand horizons further. But caries the risk that if she flakes out, you've sort of ruined YOUR 'night of a lifetime', and she's not going to consider it ever again.
The third fork is to split the difference between those two... try to have as much fun as you can, but also make sure she is having fun and wanting to explore more. Maybe even see if there are other things she'd like to include. I guess you could always go back and have slimy sex in the garage? Maybe a little something fun for both of you that way. This is most likely the best route and hopefully you can thread this needle! Have some enjoyment and keep things progressing further!
The down side is the fact that she didn't remember what she said a couple weeks prior seems to suggest this isn't a big thing, or even anything memorable for her. I mean, hell, I remember the exact date, time, setting and location my girl and I were talking about fantasies and I said I wanted to have a threesome with her ...24 years and still waiting on that one! So forgetting after two weeks, you will probably have a bit of an uphill battle.
Another thing to consider is that while you've probably thought out this fantasy a thousand times, it will all be totally new to her. You might consider mixing up some slime ahead of time...a bowl full or something small. Test it out with her, let her string it along in her hands, etc and see what she thinks. If there are any questions/concerns - probably better to discuss them with a 'test batch' a few days before hand vs after 3-4 gallons of slime hit the floor and anyone has a weird reaction like saying the smell, color, texture, look, feel, etc 'reminds me of [some bad thing here]'.
For the actual event, there are probably a zillion and one tips on here but some things to consider:
Put down some sort of 'robust' protection for your play area. It's not fun to stop every two minutes to adjust a thin sheet of plastic or worry that if you move a few inches, you spill 5 gallons of slime on the living room carpet. So splurge on thick plastic, heavy secure tape, etc - if that is of any concern.
Next - being covered in slime is probably going to get cold pretty quick. Typical 'room temperature' (especially with the AC on during the summer) can get chilly if you're not keeping active. So consider elevating the temperature, or outside on a hot summer night! if you can.
Of course, warm slime can be an erotic experience, too. So that might be something to consider. Either way, a good 'test' would be to take a shower/bath at the temp you expect the slime to be, then stand wet in the area you're going to use and see if you get cold after 5-10 minutes.
Pre-plan on clean-up. Set out some big towels, have a clear path to the shower, etc. Nothing is worse than having your fun, then making a huge mess because you have to run through the house 'slimed' because there were no towels.
Lastly, not sure on what slime you have. If you post, I'm sure others could give info on safety/compatibility. If you want to be 'absolutely sure', track down some J-lube. It's used in the vet industry for artificial insemination, so definitely vag safe! Search on here - lots of info, but you'd probably want to mix it up ~24 hours ahead of time to let it hydrate well, then you could do anything from a thin, runny slime to something thicker. But either way, you'll have a super slippery mess to have fun in.
