Looking for ideas

So, the past 3 times my wife(F39) and I(M38) have had sex, I tied her up for 1-1 1/2 hours and fully focused on how many orgasms I could give her before she tapped out. Well, tonight she is repaying the favor and I get to be tied up and just lay back and enjoy for at least an hour. Problem is shes not very creative and she is looking for some creative/kinky ideas to really make the evening fun. I told her she's in charge and I am pretty much open to anything she wants to try. The only thing off the table is my butt, and that's mostly her decision. She's going to be reading the responses, so give her your best ideas
