Picture the scene . . .

[rebbonk]

You come home from work and the door is opened by your woman who's wearing nothing apart from one of your shirts. Her long legs disappear invitingly up into the shirt and she walks slowly up the stairs, beckoning you with her finger and a 'come hither' look in her eye.

Isn't it great how a woman wearing a man's shirt can be so sexy.

Spoiler:

Of course, if it's the other way around and she comes home and finds you wearing one of her frocks, things don't run quite so smoothly.
