We entered the bathroom and Kim poured some water into the tub. We both already had nightgowns on so there was not much to take off. I slipped mine of... first by just pulling it over my head. Kim danced in front of the mirror and I stood there watching Kim as her body, well her big butt swayed this way then that way as she pulled it over her head. I could see my reflection and I saw two tiny tits and a straight as a bean body with long skinny legs. Where as looking at Kim’s body I saw big. “how will you go about finding someone then?

Then we hit a stop light. Holy hell that was.
