For me the all-time number one is on my back, legs over his shoulders or around his waist (or him pressing my knees into my shoulders

). That's pretty much a one-way ticket to a hands-free super-soaker of an orgasm for the HBLA. It's intense to look into each other's eyes while I'm getting fucked.
Number 2 would be riding on top. Doggie-style or side by side isn't out of the question, I just need a reach-around.
Now, for oral...
