Nursing Night Shifts and Unexpected Playtime

I'm a nurse in my 30s who's recently embraced being a Daddy for my partner. Last night at work, after finishing rounds and before the day shift started, I couldn't resist the playful mood that came over us. We ended up in some sweet daddy/daughter roleplay amidst the hospital supplies. It felt so naughty yet perfect. Am I just going crazy with the stress of late-night shifts or is it totally normal for adult play to happen unexpectedly like this? Anyone else had a similar experience?
