Double Entendres from a 5 year old

I usually pat/pinch/squeeze/tickle and or generally annoy and tease my daughter while we snuggle. Laying in bed watching Peppa Pig,  and she suddenly turns and says, "Spank me. Not too hard, and not to soft." Pointing her little finger threateningly in my face. As I think about how to respond to my new found Goldielocks of BDSM, I mentally decide that during teenage years, I might not want to be the "cool" mom that she can say anything to. Might want to keep some of that shit to yourself. Oh, I can't adult today. I about lost it.
