Hot New Game with My Fiancé

Tonight at work, my fiancé showed up unexpectedly. He wanted to play a new game we came up with recently, he'd dress as a customer and I'd serve him drinks while also pleasing him sexually under the bar. Once I got down there, it was intense, his hard cock pressed against me through his jeans, fingers gripping my ass cheeks as I teased him with my mouth. He pushed inside me right there on the floor between my legs, grabbing onto the shelving unit to hold himself up while he pumped into me fast and rough. Is this normal for couples before marriage?
