Vanilla

How can I get my vanilla ass boyfriend to open up comfortably? I don’t want to push him, he is the type to say openly what he wants or likes, so I’m not sure where to start. Sex is BOMB. His dick is that good good that you don’t find just any ole place. And that vanilla sex with him has got me drippin, no joke. But sissy wants to get a lil freaky without him running lmao. Suggestions on how to ease into it?
