Is it normal my sister grabbed my boobs?

She was probably just curious about you. Me and my sister grab each other's boobs all the time, usually as a joke but some times out of curiosity. so I think it's normal.

she loves u,understand her feelings.. she wanna be lesbian with u

Not really she was probably just interested in how her little sister's turning into a woman. Doesn't seem sexual to me. I know people with close sisters who did stuff like that. But if it were an older brother doing that then no it'd be weird.

It depends on your relationship with your sister. From what I assume, you have a open and healthy relationship so this is normal :)

Some of my friends do this to each other sometimes too, squeezing each others boobs and saying stuff like "damn, I wish I had a rack as big as yours' etc. Weird, but some people are quirky like that.

Weird. All I can say about this.

It sounds like she was just goofing around. I wouldn't worry about it.

haha... i kinda grabbed my sisters boob with my foot once... we we watching a movie and my foot just happened to be there so i gave it a squeeze and she's like "what the hell?!" i just laughed and said nothing and we went on watching the movie. also she sometimes demonstrates on me what it was like to get a breast exam, saying (jokingly), "sooo how's it going *rubs her hands all over my boobs*"

She's just making sure you're up to standard.

That is weird indeed.

Developing nicely? Wow. Thank your lucky stars you were born female.
