I have embarrassing news to deliver, probably a full month before you noticed the prominence from the viewpoint of your eyeline, everyone standing to your side recognized the female-only curvature on the lower profile side... If you had pecs to build on before, well, make that 6 weeks and it was like VERY obvious that something was, shall we say, odd.
And yeah, I was outside, shirtless, splitting firewood, with bouncy newby breasts, swinging a big double bladed axe, and had no idea. oops. Fortunately, sometimes I think people edit their memories as they see things that don't add up and make them fit the most likely; so no one confronted me; then again, I did have a big double bladed axe in my hand... eek.
