Oh well, with some luck indiggy may find this useful.

I myself am not focused as much on the limpness of the dick, but I do enjoy scenes where the bottom is in a lapdance or similar position and rides the top in a way bottoms dick keeps hitting his abdomen. Hard dicks slap nice and make sound, but limp dicks have a wider range of motion, I can enjoy that, so several scenes came to mind. Your "bareback" condition limits the choice somewhat, but even so, see what you think about these:

Firstly, and it is a bit of a surprise he was not mentioned, there is Alejandro Dumas. He is a power bottom and almost always limp, though he wears cockring and in many scenes covers his dick. Still, there are 2 scenes from TT worth checking out:

From the same studio there is also Joaquin Santana, he sometimes stays limp through the whole scene (and may generally be worth looking into for this sort of fetish):

Then there is Italo Gang, another power bottom. I enjoy him because he is very flexible and can do a pose where he is fucked while holding one leg almost vertically up. And also his hip tattoo. He has 2 scenes where he demonstrates that with limp dick from EV:

The rest will be just scenes rather than specific actors. In some here bottoms are limp dicked in that specific lapdance position and later do attmpt to get it up for cumshot, but still, may be worth a look:

Finally, see what you think about this one, here bottom is more or less limp most of the time, but does attempt to get it harder on several occasions:

I'll see if I remember any "cunt/pussy" talk vids. In the meantime, what's your take on fully black or fully latino guys (by "fully" I mean both top and bottom) doing this?

And fuckall I think it's hilarious when I see a guy getting a bj in a vid and he can't get hard - it's like, why even include the scene in the movie lol
