<human>: So here's the situation.

A and B are friends. I met B a few days before A and there was definitely attraction between B and I from the start.
I ended up hooking up with A 2 weeks ago (just some making out and stayed the night in her room). A made it clear when I tried to invite her out again that it was "a one time thing." Ok. Case closed on that one.

*But girls talk to each other*. Especially friends..

Anyways. I texted B to join me for coffee today; she asked "it's not a date, right?". I replied "No, it's totally a date. Candles and shit, too." and eventually got her to agree to meet up. At this point, I'm already thinking that my hookup with A may be hurting me here with B.

So we are together for that "date" today and B brings up what happened between A and I. She jests me that it was a "rookie mistake" to try to get together her (B) so soon after A. 
I think she was trying to catch me off guard with that, but I was stoic about it and told her as soon as she started hinting at what happened with A. No shame in my game.

Aside from that, the whole "date" went really well and was a lot of fun: teasing, flirting, etc. She tried a few times to make it a "just friends" thing, but I kept the interaction quite sexually charged and made sure the kino was abound.

We definitely had fun together; I can tell he wasn't expecting me to be... me. 
This girl is used to chumps that puppy-dog after her, but I didn't give her the satisfaction. We have similar "attitudes" and there was a good bit of banter back and forth.

But from B's perspective, it looks like she was option #2. Game-killer. Nobody wants to be the fallback.

Can you condense the text into three sentences or less?
<bot>: Hooked up with girl A, then went on date with her friend, girl B. Now Girl B looks like the 2nd choice.
