сосать

To blow, to give a blowjob (in fact the Russians do not “blow” but “suck” when fellating). Serves either as a direct term for performing oral sex or as a figurative expression meaning to suffer a major loss, fail miserably, or endure a terrible situation.

Прилюдия стандартно: полизала яйца, потом сосать. Особой выдумки не наблюдал, нормально, но не более.

Standard foreplay: ball licking then blowjob. I did not notice any particular inventiveness, OK, but nothing more.
