I was watching an anal sex film the other day and a bloke was fucking a girl up the arse with his mammoth thick nine inch cock.
The guy then pulled his knob out of the girls arse. You could see it was bursting to cum. He put his big knob towards her face and beckoned to her to suck it. She didnt look too happy but spat all over it and wanked it a bit before putting it in her mouth.
This kind of really turned me on that she was aware it had been deep in her arse. She must have felt that knob inside her rectum. Then being made to suck it she felt she needed to clean it with her spit, even though it was squeaky clean anyway.
