Roughly

Pam was right although you held off taking towards Harley because she was Pam's girlfriend and currently she was supposed to be your therapist you couldn't let this continuous stream of disrespect to continue you were her master yes you were kind most of time but there is a clear difference between being nice and being a doormat you needed to reassert dominance plus who wouldn't want to spank her bubble butt?

Slapping your hand down onto Harley's pert ass was extremely satisfying I was lost in the moment for a minute until Pam cleared her throat to remind me why I was doing this in the first place fifteen smacks later and she began to squirm around in my lap trying to escape but I held her tightly and continued to beat her ass like a drum.

When I was done both cheeks were burning red Pam gave me a salve cream that she made which let me know that she planned this from the beginning but I didn't say anything and gently applied it to Harley's behind which initially caused her to flinch in part from pain but mostly from fear she relaxed when she realized what I was doing and I could hear a sigh of relief as I continued rubbing her ass.
