secret experiment tonight

me and my partner have this thing where we occasionally spice things up with some roleplay. last night i decided to push the boundaries a bit by setting up an experiment to see how far i could go without her saying stop. it started tame but i kept pushing harder, asking for more explicit acts each time she agreed. eventually we hit a point that felt too intense and i backed off. weirdly enough this made us feel closer than ever before. why does playing with consent limits make things so interesting?
