"Your tits look really nice"

I say.

Millie flinches, and says:

"Excuse me?"

"Oh, sorry, I did not mean it like that. Your tits look really great, have you had them enhanced again?" I say.

Millie smiles, both from relief that is what I say I meant, and from hearing the compliment. I know she has always been proud of her big tits.

"Thanks Matt." Millie replies, and continues: "Yes, your dad got me these," her hands moving to her big tits and pushing them together, "for my birthday as a present, or rather as a present for us both. They came out really good I think."

I look at them in detail. Since the conversation is about her big tits she cannot say that I am staring at her tits now, I think to myself.

After about five seconds of looking at them very closely I say:

"Really very nice, congratulations."

Millie pushes her big tits together, looks down at them and smiles, and says:

"Thank you."

I know what I want to ask next, but how bold do I feel?
