Overview: A HB7 that I know as a very casual aquaintance through a female friend of mine had suddenly started texting me, 3 days previous, showing IOI such as asking how I've been, non-stop texts throughout the day, inviting me round hers to "watch" the world cup etc.
It starts out innocently but Im flirting from the start (I always do), she reciprocates!

Anyways. Its day 4 and we r texting. She mentions she is watching the football but is bored, so I text back "plenty of other fun things to do ".
She asks "like what???" and I innocently reply "most of them involve 2 consenting adults"
Theres a short delay to her reply, but she jokingly deflects me and says that I could make love to the dog if i wanted (apparently the dog is gay - (i dunno...)). I C+F - neg with "Woaaah! what were you thinking that i was thinking? Im not into beasteality! ...and besides, hes a big dog but hes still a pup - i'd get locked up for peadophilia too "
Theres a short pause and then she texts back asking me to come over and cook her some food cos she's starving. Im in.
I C+F her again "cook? jeeze what did your last slave die of?"
we banter back and forth untill i tell her that i'll come over just to make sure she doesnt burn the house down.

Anyways!! fast forward about an hour in and there has been lots of kino so far We are watching a film and shes looking tired. I do the lame old cinema routine of putting my arm round her, then pull her towards me so her head rests on my shoulder. she doesnt resist.
10 mins later i pop a modified version of the "Do you want to kiss me" line

me: Can I ask you something? (said innocently)
her: yeah
me: What would you do if I kissed you right now?
her: Ummm... uh...
me: wanna find out?

she turns her head towards me and plants one on my lips. We spend the rest of the night making out and fooling around. Eventually we fall asleep on the couch.
Didnt escalate to sex (but I think I could have got it) because I got the feeling that she would want a relationship out of it. I enjoy being single at the moment and dont want to be an asshole to her because she's a friend of a friend
