We both enjoy the look and feel of our asses opened up, gaping and stretched, rosebud exposed. We find it is a combination of almost all of the techniques already described below….definitely ass up and shoulders down, preferably even bent over on your stomach over the back of a sofa, chest rested on the front edge of the seat cushion, hands on the floor for any needed support, your play partner standing behind the sofa, doing as they please with the new you view and easy access! This grew out of our pleasure with anal explorations of all kinds… I find that after she has deeply pegged me, or fisted me with more of a plunging in and out method, that my response is to push out against her invading fist… which further relaxes my anus and allows my rectum to remain open. This also produces some wonderful rosebuds, and if that is one of our playtime goals, then I will use a vacuum pump after cleanout, pumping my anal lips to a nice puffy and sensory heightened state.
She was amazed and erotically responsive the first time I bent her over, after fucking her pussy excessively rough, and then stuck my fingers inside her and used two of them to push back out through her ass! Next time we play I plan on using the vacuum pump on her asshole again, as well as a small one on her clit, making both nice and swollen. Then, repeating the above only with two, maybe three fingers curved through the back of her pussy and out her puffy puckered and rosebud ass!
For me, she instructs me to push out against her strap-on or fist(s), bearing down and holding it while she pummels me and my ass relaxes and opens wider, following her outwards and then staying there, open and ready to suck her back inside me.
Advice is to go slow, work up to this kind of play, take time to warm up and clean out completely, and then use TONS of lube. This makes the pushing out and bearing down safer and cleaner, although there are never any guarantees with anal play so agree beforehand that shit happens! As for prolapse, we haven’t gone there and have no desire to. Everything short of that is already enjoyed and part of our repertoire.
