My Wife Fingers My Butt Hole

She started sticking a finger in my butt as she sucks my cock years ago. She tongues me some as well. Over the last few months she has gotten more aggressive with her tongue. Instead of sliding between my legs she put my on my elbows and knees tugged on my cock with her tongue in my ass until she milked me.
She definitely had a kink she wanted to play out. She pulls out a toy cock. Can I use my toy on you? I looked at it and did that’s not one of your toys. She giggled and said this is a starter toy. I came like crazy as she pumped my ass with that thing.

We have moved on to full leather high quality strap on harness. She fucks me the too one. She stuffs a vibrator in her and she cums hard fucking me.

Does this sound okay, healthy for a marriage? It’s not bad, I like it but don’t want this to be the main focus of our sex.
