Here is the situation:
I was getting up to put the classwork in the classwork bin, as I do this I check over my answers and I notice the girl I've been texting a lot is coming over to do the same, she pushes me with her side and says "move."
I just do a ":T" with my mouth and squint at her and she smiles. I put my work in the bin and as she opens the door she takes her sweet time and so I tell her to hurry up and she tells me to shut up. I smack her ass and she walks out the door and tells me she's going to slap me, I "heh" it off.
I turn around into the classroom to make sure I did not forget anything and begin to head to the cafeteria (all in less than 3 seconds).
I tell her "Then do it!?" She comes up to me and smacks me one, two, and a third attempt to hit me harder haha.
I laugh it off and ask her "Will that help you sleep at night?"
"Yes" she says.
"I'm glad" I tell her.
We don't see each other after that and then I text her later that day:
Me: Was that third slap an attempt to hit me harder? >:p
Her: Yes

Me: Well it didn't work :p
Her: Well it doesn't matter, do that again and I will rip your hand off -_- you crossed the line, are you crazy?
Me: All I read was blahblahblah
But keep it up, it's cute
Her: -_- I am serious that was so disrespectful
Me: How?
Her: -_- *My name*
Me: Yeah, you did not like it AT all.... I could tell by that third slap
Her: -_- I'm going to tell my boyfriend if you keep joking like that
Me: Oh cool, what's his name :p?
Her: You don't need to know that, stop joking like that dead ass
Me: It's alright, if it makes you uncomfortable I will stop, I understand and respect you as a woman :pp
Her: But you say it w/ the tongue, no I lied lmao I don't have a boyfriend, but seriously, don't do that again, that's disrespectful
Me: Making up a fake boyfriend... Now I know your last one didn't spank you hard enough ;p
Calm down before you have a heart attack o.O
Her: I'm not speaking to you no more or doing anymore projects with you, seems it went to your head
Me: I think you did not read my "I'll stop" text...
Buttttttt have fun with that!
Her: Good Night rooster (Nickname for my name)
Me: Good night weirdo! :p
Now I want to ask you guys, how did I handle this situation? The only material I have read are the ones posted and the ones I've researched for past situations that have occurred.
I don't really give one flung about how she took me smacking her ass because I do not regret doing it.
Her ass is also very beautiful and round.
Should I act like it never happened tomorrow when I see her in the morning or what?
I am also much stronger at texting than I am at oral flirting, is there a way to improve that? With text I have time to think what I am going to say, when she's right in front of me I have to act quick!
