you're the "player"
you should know how to stimulate a woman's breast.
all girls like different things.
some like them to be nibbled, sucked, licked, all of the above for me

some like it more rough, others just like gentle sucks.
just try different techniques.
read her vibes and reactions to see which ones turn her on the most.
or just ask... does this feel good?
see!! and you thought she'd never been turned on before.
