I tried my girlfriend’s toy in the shower

I was at my girlfriend’s today and noticed she’d left her toy in there. I’ve tried toys before and never really got the hype but curiosity got me and I tried hers while she was asleep so I got in the shower took her WhisperRabbit started on the lowest setting and rubbed my clit a little, then turned it up and slowly put it in… As soon as it was in I got way into it and my legs were shaking afterward. I haven’t enjoyed myself that much in a long time. My girlfriend and I have had sex four or five times but I’m usually the top. Being on the receiving end was a whole different experience and I wasn’t expecting to like it that much. She was asleep and the toy was dead quiet but also the shower was running so I don’t think she heard anything. But idk how to tell her I tried it by myself.
