My second hands free wet orgasm

Hi members. I haven’t been active in a while. Took a break from it all, life gets busy I think we can all agree.

last week I had a day to myself and felt in the mood to try my helix syn V again (vibrating model)

I had zero expectations and lots of time on my side which is often rare these days.

I had the syn V in while doing a little housework and in certain positions it felt good. I decided to stop chores and laid on the bed to see where it took me. Fast forward to roughly 30 to 40 mins in of relax and enjoying little pleasure areas I started to feel very good.

i let my body do what it needed. I ended up laying on my stomach and doing pelvic style contractions with the vibration on a medium setting. Things were feeling so good.

then I felt the build up. At first I wasn’t sure of the feeling but decided to let it ride.

I was moaning (please neighbours don’t hear me) and then I had the orgasm release. It felt amazing, lasted roughly 30 seconds. However I did have ejaculation in my underwear. 
from what I read with other members it’s usually a dry orgasm with pre cum after. 
no no, I had a half load in my pants after.

i didn’t care about the clean up, the experience was great probably 5-10 times better than penile masturbation session.

Is it normal for hands free wet orgasm?

I feel I didn’t do anything wrong because it still felt very good!
