Alright so I met an HB7.5 at my freshman orientation for college. Things went well and we exchanged numbers. I initiated a text conversation with her and it started off a little boring but I was able to pick it up by asking her about her lifeguard job. Here's where I'm at. Help would be appreciated!

Her: all these little kids get annoying at times
me:I'm sure you're a pro at blowing that whistle by now
Her:Oh yeah I'm a pro at blowing things hahaha
Me: Whistles are called the gateway blow for a reason. Just leads to bigger things
Her: Haha I started on bigger things though which is why I'm good at blowing my whistle\
Me:Some lifeguards barely blow the whistle and its really soft. Personally I like it when they blow ther whistle like its going out of style. You a softie or a hard whistle blower?
Her: Oh hell no I make that whistle my b*$%h!!!!!

Anyone care to suggest the next move? She lives close to my lake house so if all goes well then y'all know what could happen when I get her to the lake. Anyways help is greatly appreciated. Thanks.

She was giving you a window of opportunity to turn the text conversation sexual. You could have easily have taken that "I'm a pro at blowing things haha" comment and escalated it further. Unfortunately it seems like you didn't really want to push it, or didn't know how.
The important thing though is that she is sexually interested in you. All you have to do now is make it happen. Invite her over, keep the sexual tension rolling and then seal the deal when you two are alone.

Don't overcomplicate this shit and don't second guess or doubt yourself. She likes you. It's that simple.

good luck
