[FFM] That time my sister saw my husband’s whole cock

So I (29f) have been married to my husband (30m) for about 6 years.

When we were still dating, I was staying over at my sister’s (27F) house for a few days. My husband and I had just started having sex in the relationship so we were pretty horny and bummed we couldn’t be together so we were pretty heavily sexting.

Fast forward to later that night after a few drinks and heavy flirting and I dared my husband to send me a dick pic (we hadn’t really done this yet in the relationship).

He obliges and I open my phone to hear my sister say “oh my GOD!” From directly behind me. She’d walked by, behind where I was sitting and happened to be looking the exact moment I opened my phone.

I turned around to find her eyes really wide and she just says “damn, [husband] has a big dick.]

And because we don’t live on a porn set, she shook her head and walked away.

Shes mentioned it a couple times in passing but I have caught her staring a few times. Made me wonder how big her long term bf is….so I asked her. She just smiled and said “He’s great…but (husband)’s was just shocking”
