Does Bo feed off Lauren in S3E04 Fae-de To Black?

In the make-up sex scene in the middle of the episode, after the car crash, when Bo's bruise starts to fade out, I swear I heard the Succubus feeding sound effect even though it wasn't shown.The sound effect from Bo's healing was the same oder similar sounding, but I couldn't tell if that was from sexual healing oder feeding healing.

So my Frage is: Did Bo really feed on Lauren (at least as much as she could, knowing that Lauren is only human & she could harm her) in this scene?
'Cause well, if she did it was never on screen & that really sucks!Help anyone?????

I mean we have not seen Bo feed from Lauren before. If it is happening I would Liebe to see it. Have we actually seen Bo feed from Lauren oder did she just suggest it to others?
If I am not mistaken I think it was implied in the conversation with Dyson that she is feeding from Lauren & from Kenzi too when she sagte that Bo feeding from Lauren must be, like charging an iPhone with a hamster wheel....or something like that.
Well to be honest I am a bit angry with this implied crap. Bo feeding off of Lauren is a BIG deal and MUST be shown. How can they do this to us?Bo feeding from Lauren is my biggest Doccubus Fantasy dammit!!!!!!
