Sign of playful flirting/attraction - she says she'll slap me when I ask for a hug, but is still close with me?

Yeah so a colleague of mine has offered a whole bunch of flirting signals these past few months but I've not been too invested in it, as she apparently has a boyfriend. But it's all good... We're very close as colleagues, for work reasons.

I've given her non sexual hugs before when we've had little arguments when she was angry or unsure if I "liked" her (presumably just as a colleague), to offer reassurance we are sweet.

Lately she's been a little more distant and distracted with text messages, but whatever. Without being overbearing I've been texting as usual (usually within the context of work but with sexual innuendo thrown in) - and I don't think she wants to be seen texting too much if she's around her supposed boyfriend. Definitely been more dry and evasive lately.

But earlier on I text her saying I owe her a hug if she's still upset with me (work shit, we got angry with each other due to a miscommunication about something), which she kind of evaded. Then in person I made the same joke/pass and without exactly being too serious she went along with it sarcastically saying "huh yeah then I'll definitely slap you maybe the police will be called" - she actually looks after me at work and has always said I can't annoy her compared to others...

I just carried on goofing it off and pretended to slap her around the waist as she walked off.

Anyways later that night in the office as we were getting ready to leave she got up and put her hand on my arm gently as she said goodbye

Does this sound like sexual tension/attraction?
