To take the doggy-style position, i.e. 1. have sex doggy-style; 2. to be between a rock and a hard place.
В миссионерке немного помучал ее — дырка вроде тугая и нераздолбанная, но алкоголь давал о себе знать… а вот когда я ее раком поставил — тут уж совсем другое дело!
I tormented her a bit in the missionary position, the hole is kind of tight and not worn out, but the alcohol did its job… but when I took her doggy style, that a completely different story!
