Not really, no. You're basically rubbing and squishing the clit against the edge of the table, so it won't be that much difference between twiddling it like usual, but with more pressure. The reason that desk masturbation are popular is that you can also stimulate the parts of the 'shaft' beneath the clitoral hood and parts of the 'body' (corpus cavernosum) normally hidden beneath subcutaneous fat because of the extra pressure.
Ah, Eh? Ah,(in a high pitched voice)W-W-W-Welcome back.
