After the act of bare back anal sex with an uncircumcised penis and finding shit under your foreskin.
I fucked Terri in the arse last night raw and when I went to clear my dick I found a sneaky hitchhiker.
The act of pouring icing sugar on someone's head while they are performing oral sex on you.
Last night when I was in the kitchen the missus started giving a blowjob, so I reached for the icing sugar and totally turned it into an Alaskan Snowjob.
