Ants In His Pants

Hubs friend was helping him with a backyard project.
While my hub was operating a trencher his friend came to the back door covered in red ants. Shower was all he said as he hurried to the bathroom. I was following to help if I could and he had his jeans down swiping ants off his legs, then he yanked his boxers down. Oh my, his dick was bigger soft than my husband hard and I was staring at it a few inches away. I don’t know why it came out like this but I just said “ wow, yours is so much bigger.”
Shower water was running and I could hear the trencher running, I reached out to feel him. I couldn’t believe I was doing this but I was and I became extremely aroused as he did. I could put but of my hands around it and suddenly he’s pulling my shorts down.
There’s am checking out the little window to see my husband still running the trencher as he starts pushing in me. I started to orgasm in just a few seconds as I kept saying I never had a big one before.
Maybe a minute in and not nearly all of him in me I started orgasming and he shortly after. There was no stopping as both of us came. We didn’t know what to say to each other but please don’t tell my husband.
I have never had an orgasm like that before and I’m thinking about how I want him again. I love my husband but that orgasm was incredible.
Is it always like that with bigger penises?
