For me, a girl wit big breast or small breast is not really important..
if u bf really loves u , he wont care bout ur breast...
if u really love ur bf so much, i dont think u need to impress ur bf by wearing bikini n looking for solution to make ur breast big...
the best is get inside the room and hav fun wit ur bf..
i think it is a better solution..
guy will feel secure when u give urself to him..
this is just my 2cent....
