Inside her ass.

You bury yourself to the hilt and she squeals, arching her back and pushing at you again as you jet forth inside her, shooting your seed over and over into her asshole, filling her with it as she cums as well. It seems to go on forever, and she reaches back to milk you again and again, squeezing every last drop into her ass.

"Ohhh..." she shivers, as you finally withdraw, and she nearly collpases against the wall. She stays like that for a long time, panting, before she recovers. She stands up shakily and zips you back up, tucking you away.

"Good work, Tiger," she pants, flushed, her hair in dissaray. "Let's...let's go ahead and get you your pay for...services rendered." She shivers again and smooths down her uniform, then leads you back to the lobby.

Outside on the empty, silent street once again, you almost can't believe what just happened. But the money in your wallet--and the memories--are real. All in all, you think you can call this quite a successful venture.
