something ive seen very little of that should be waaay more popular is detachable spikes; however im not talking to the point they can just take it off and leave it somewhere. the important connections like sensory lines and transfluid reservoirs are still attached. this is intended for non-invasive maintenance, but used almost entirely for self-servicing purposes.
interfacing is fun, sure, but finding even a casual partner can be tough. trust is hard to come by and toys only cut it for so long before one needs the real deal. enter the detachable spike. because it's real, it's very warm, which already makes it better than a toy. it's also sized to match its accompanying valve; not too small, not too big. just. right.
just inserting the head alone is enough to make the average mech overload. all those sensors pinging directly into the pleasure center of the processor as you ride your own spike. truly nothing compares the feeling of fucking and getting fucked at the same time, because unlike regular interfacing, the sensations line up perfectly. every clench of the valve as the spike slides deeper and deeper until there's double the heavenly feedback pressing against the ceiling node. it's almost too much when overload hits, your own transfluid filling your valve, stuffing yourself so full.
self-servicing has never been so good.
