So I was at this chick's dad's house, and she was giving me a blowjob. Without going into the details, we were in a position such that, if her dad (who was there) had come up the stairs, he would have seen this immediately. So she says, part way through, "You know, I don't know what I'll say if my dad comes up."
I replied, "You'll probably say something like 'ahuhlahuhala'." [That's supposed to be her trying to talk with a wang in her mouth. It works better in person, I guess.]
