Changed colours of Duke II ejaculating

Like the regular Duke II, the Duke II ejaculating (with a cum tube, detachable hose and syringe, especially for Cum Lube), used to be offered in plain Black for immediate shipment and custom made in any colouration people desire.

Since we have this toy for quite a while now, we change the default colours to the dark-red and black combinations that people most often order custom made.
