Jane was sat at the back of the punt, while her husband Andrew was steering behind her, across from her was Susan, and her husband Steve was steering from the front. It was a beautiful sunny day on the river.
Jane said, "I'm hot, I'm going to take my top off."
To which she took her brown t-shirt off, her tits bounced free as she hadn't a bra on, her beautiful breasts with brown nipples stood erect and exposed for everyone to see.
"Take your top off too Susan" she said.
"No, I'd be embarassed"
The two husbands both looked eagerly at Susan.
"Go on chicken" Jane laughed.
After 10 mins of asking, Susan gave in, and very tentatively, she too took her top and bra off, exposing her modest white breasts, and pale pink nipples, which looked in sharp contrast to Jane's ample pair.
Both guys looked very excited, as they both had obvious bulgers in their shorts.
All the people on the river bank and hanging over the bridges, all stared in amazement at the punt passing by with the gorgeous ladies on sailing by topless.
The tension in the boat was getting very highly sexually charged.
After the punt ride, they all took their picnics and found a secluded spot in the woods, where there was a piece of open grassland.
The ladies spread the picnic blanket on the ground, still naked from the waist up, and they all sat on it and tucked greedily into the hamper.
Jane was eating a cream cake, and a blob of fresh cream landed on her naked breast.
"Hey Susan, can I borrow Steve to come and lick this cream off my breast?" Jane said saucily.
