You guys make me laugh-SUM
SUM is Missionary position, standing up. Look at it this way.
Instead of the provider laying on her back, legs spread and you are between her legs fucking her on a table / bed. You, the male, standing up on 2 your legs, like your walking. She has her legs up by your shoulders. This keeps her from wiggling away. You are bouncing her on your cock. Asians enjoy it. The reaction should be something like: very vocal, 1) you crazy, 2) don't stop, 3) they should be very happy.
[QUOTE=BobJohnson2;5763458]In SUM, is the WG laying back with her as near the edge of the bed an her legs up in the air, and the monger standing up at the edge of the bed, banging strait in to her pussy? If so, I do that all the time, just didn't Dow it had a special name and acronym.[/QUOTE]
