In the red shirt pictures, they're both with Amy. This is making me think.
Plot Bunny 1: The shirt doesn't belong to Chris or Dave. Instead, it belongs to Amy.
Plot Bunny 2: Dave sleeps with Amy and leaves his shirt there. Then Chris sleeps with Amy and needs a shirt and Amy lets him take that one. Chris, of course, has no idea until later that Dave also slept with Amy.
Plot Bunny 3: The shirt belongs to Amy's husband. Amy and the husband play with Dave and lend him a shirt when he gets to leave the house for a short period of time between sex. Then Amy and the husband play with Chris and lend him the same shirt when he gets to leave the house for a short period of time between sex.
