Sorry to hear you didn't enjoy Kat; I saw her this morning, my second time with her, and enjoyed her again.
DFK, deepthroat, ball-licking (could've done with more eye contact I suppose) but then missionary, doggy, vigorous cowgirl and oral to finish.
I can only think she maybe had 2 sessions close together, and didn't give 100% on the second session i.e. yours. Unacceptable, whatever the reason.
I had almost picked Amy but was too slow; someone else took her. Thought she looked very hot, slathered in tarty make-up with her black lingerie & stockings.
