The weekly Bar-B-Q and Toga party at the hotel was tonight. Allen and Sam had repeatedly said not to miss it for any reason because it great fun and the highlight of their vacation. Toga dress was mandatory for admittance with costumes available in reception. I went to the hotel lobby and was handed two toga costumes, scissors, needle and thread and was told that we could alter them any way we wanted.
On my return to our room Irina and I found two well made costumes. When we tried them on we discovered they were also very cleverly designed to show a lot of flesh. Sam's was a Roman tunic costume held together with a red rope at waist. She could not wear panties with the costume due to it being open each side past her waist. On Sam, it looked deliciously provocative. I was concerned with her wearing this costume because her tits showed a lot and she could not wear any panties. The costume was not made for a tall girl and was half way up her thighs. Every time she raised her arms a lot of her ass would show below the costume.
My costume was simple and fit perfectly. I could not wear any underwear due to the costume design exposing one hip. Just wearing it to the party produced excitement with my cock swinging about freely under the costume.
