permission

Any scenes where guy asks girl permission to fuck her in the ass ?

I'm looking for clips where a girl (preferably) or guy asks permission to cum. Here's an example. Click where it says view trailer or something like that: http://www.waterbondage.com/site/shoot/4971-Claire-Adams-Does-Sabrina-Sparks.html

Just saw a clip in another thread, and gave me the idea for this... Any clips of the girl saying "let me do ...." or "allow me to....", but basically taking control in that sense. I know it's weird, but just watched clip 2 from this and it turned me on...

I love these vids, where the girl gives the guy permission to cum inside their pussies: Vid 2 - "Cum right in me" http://www.bordolino.com/bbn/g-bn-1062d/Grlfr_Hghsc_hrfrs.html Vid 2 - "Yeah, go ahead... go ahead" http://www.theadultdvdcollection.com/gallery/196/index1.html Anyone have some more?
