The best orgasm experience imo, is doggystyle, ass way in the air, head on the mattress, slam it hard with no hands, pelvis will slam forward and back against yours creating a huge smacking sound that will cause squirts galore.... if your in shape, you can do this hardcore non-stop without breaks and both of you will be worn out in no time.
I can't do doggy much, his penis hits my cervix hard in that position and he can't go the whole way. Damn. lol
