Wife's Wild Surprise

So here I am, been married to my wife for five years now. We have a good thing going, but lately, she’s been hinting at some kinky stuff that caught me off guard. Last weekend, she invited her old college friend over to our place, said it was just drinks and old times. But turns out, her “friend” brought along his boyfriend for the night too. I didn’t know what to expect, but my wife pulled me into our bedroom where these two guys were waiting. She said they wanted to help me relax and explore some new things together. And man, did it ever. First off, there was the sheer novelty of it all, the four of us in one room, her fingers slipping inside while his tongue worked magic on my clit. I felt myself getting wetter with every moan she let out too. Then we moved to a more hands-on session where both guys were jacking me off and sliding their dicks into my ass at the same time. The sensation was mind-blowing, every inch of me being touched, stretched, filled in ways I never knew I craved. After it all wrapped up late that night, we got to talking about more setups like this for future dates. But now I’m left wondering, is this normal? Am I losing my head over wanting more of these intense group sessions? What’s next? Give me some advice, please.
