Me ofreces a tu jefe por una noche para obtener un ascenso

I have agreed but I'm still upset/disgusted by the whole idea, but we need the money! Initially resistant, I start slowly enjoying it. The boss is definitely taking advantage of the situation and I ask you consistently if you are happy with what you have to sit and watch! Finally we can say you have achieved receiving your promotion as your boss uploads a huge load all over my pretty little face!
