CMS - Deep Servicing (Arcee/Carly) (Patreon)

Arcee's in for a routine tune-up and idly waiting for her servicing, unaware that she's giving a deep 'servicing' to Carly, stuck helplessly under Arcee's copious trunk.

Commission for KeyofIth4, one of my lovely Patrons here, who kindly commissioned the Arcee idea from September's Patreon Poll!
We decided that Carly from Transformers G1 would be a better fit for the idea than Mikela.
