My wife just returned from a workshop over the Weekend. She was acompanied by a female colleague (Anna) shes friends with. They get along very well and also meet outside of work, I have also met her. Shes in her late 20s, blonde, long hair, tall and athletic.
They shared a hotel room for one night. Doublebed was cheaper so they agreed to share a bed.
My wife sent a selfie with her colleague and I immediatly thought: "her boobs are bigger than I remembered.... "
When my wife returned she told me about the trip.
In the evening after the workshop they went for a walk and talked a lot. Anna told my wife that she was pregnant but really early (week 5). She noticed because her boobs got bigger

of course I told my wife that I have also noticed her boobs and she laughed.
When the girls returned to their room they changed to their pyjamas.
My wife undressed first, she stripped completly naked and walked to her suitcase to get the old oversized tshirt she usually sleeps in. It is white, very thin and barely covers her ass. She wore no panties. While my wife was naked they just continued with their conversation.
Then her colleague started to undress. She removed her shirt and bra and my wife said "wow, they are really much bigger" Anna turned red but did not cover up. She grabbed her boobies, looked at them in the mirror and said "a few more weeks and they are as big as yours". They both laughed and Anna but a Shirt on. Unfortunately she jept her panties on.
Of course I asked my wife to describe her tits: they were a small C cup, a bit saggy, with hard tiny pink nipples. Anna was tanned but no tan lines on her tits so she must enjoy tanning topless.
While sleeping my wife moved around a lot. She told me when she woke up she was lying on her back and wasn't covered by the blanket anymore. Her shirt slipped up now barely covering her boobies, but her pussy and trimmed bush was fully exposed. Anna was already awake brushing her teeth so she must have seen.
For a long time Anna, her husband and my wife and me wanted to visit the sauna together but never found the time to do so. Now I am really curious.
