I made a royal screw up, left lubricant on nightstand

r/

So, for context, a friend (he left my school a couple of years ago) gave it to me as a joke. I (15M) used it last night so I could fall asleep easier, accidentally left it on the nightstand, and my mother found it, She will interrogate me tonight after I return from school. I know I should take responsibility, but other than that I don’t know what to do. Please help, I’m genuinely scared.
