What's next?
this is too much: follow her discreetly
you quietly follow her as she enters Serena's room.
Right after she enters, you hear Serena squeal in surprise. Then you hear them talking and laughing...
It lasts a moment, their discussion is more discreet. Finally you can't help looking through the keyhole:

you can't believe your eyes: is it really happening! You see the two girls exposing and staring at their bare breasts!
As you imagined, those of Serena are two beautiful plump and smooth breasts, which you want to knead. Those of the girl are smaller, but cute that you want to pinch nicely.
They're both blushing, as Serena says, "You don't have to be jealous, small tits are cute too! Just highlight them! Wait, I've got something for you " she says, then they both go out of your sight
