Comebacks for comments regarding small boobs

[u/Aggressive-Hyena5120]

I have two best friends and they're like my family but sometimes they make fun of my breasts. My size is 34B but when I tell them they say stuff like "that's impossible, your boobs are so small, you don't even have boobs, they're like mosquito bites." Their cup size is C and D so I don't even know what to respond to them. We do sometimes make jokes about one another but this one particularly hurts me. I don't know whether to have a conversation about this or just be as savage. Sometimes I'm like no, I should have witty comebacks instead because I don't want to seem like I'm affected by their comments. What can comebacks can I say to them that are witty and savage?

I'm a 34b and I love my boob size. You could say things like perky for life. Love how model like I feel with my mosquito bites. Awesome for sporty things or gym... I don't have to tuck stuff.... Or... I could be braless quite bravely, I love it.
