Go to town on her giant breasts.

Erza's eyes glow red again. She has a yandere smile. She says, "get ready for my gigantic breasts."

You nod before Erza puts your face in between those beautiful boobs. You think to yourself "Wow! These are so soft."

After a while you grabbed the massive boobs and began squeezing them. Erza says, "that's right. Love your queen. These boobs are all yours. This beautiful body is all yours my love. Only love me and no one else."

When you finally took your face out of Erza's breasts, you're face was as red as Erza's hair. You kiss all over her breasts. You suck on her nipples until milk comes out. You say, "Now it's time to play with the rest of your body."
