Would my husband bed the y busty au pair if i were not around?

Our au pair is 21.Shes on holidays with us at the moment in St. Barts. She gets on real well with my husband. Shes stunningly beautiful, she has a body like Naomi Cambell, but the of a Page 3. Shes actually 30F s and they are natural. My husband is constantly checking her out and her bikinis are just so y. It is a case of her comes my then me. We have two kids so shes constantly by the pool with us. She gets on great with my husband. I feel really jealous. Will he be turned on by her? Can i say something to her without sounding jealous and bitter. She has even gone so far as to let the straps of her bikini down when on the sun lounger to a flurry of horned up guys ping and starting. Can i say anything to her? In the evening when she comes to dinner her outfits are so y and she is being hit on like crazy, even by woman!!! She is a wet dream no doubt. Can i say anything? Do you think my husband notices? First day i could have sworn after she appeared by the pool he developed a bulge in his speedos. All the games involves alot of bouncing around and there is alot of bounce going on? I la
