Boob, titty, melon. Derived from the colloquial nursery term сися (an affectionate word for a mother’s breast). In everyday slang, it is a highly popular, visually descriptive, and casual noun for a woman’s breast (она была в открытом топе, и её сиськи так и бросались в глаза — “she was wearing a low-cut top and her boobs were totally out there”).
В сиську полную впившись рукою,
Хуй в пизду до мудей он вонзил
И обильной, горячей струею
Матку жадную вмиг оросил…
With his hand buried in a full breast,
He thrust his cock deep into her pussy
And with a plentiful, hot stream
Instantly drenched the greedy womb…
(Анакреон Клубничкин, Сатир и нимфа)
