Walk in on her in the bathroom

Wednesday before Thanksgiving: the grandparents volunteered to watch the kids. My younger brother and you are taking your wives on a double date.

Your sister-in-law with the hidden big tits is getting ready in the bathroom.

It’s a small house. You make up an excuse. You have to piss really badly. You’ll just walk into the bathroom to use the toilet. If you happen to see my brother’s wives bare breasts, then you’ll apologize. After taking a mental snapshot of course.

Or maybe you should take a real snapshot. It’ll last longer.

No. No phone. You excuse accidentally seeing her naked, but you can’t explain blatantly taking a picture. (You make a note to take a real picture of her fat rack later.)

You hear the shower. You turn the doorknob. It’s unlocked. Steam escapes through the crack in the door. You peek your head in. Unfortunately the shower curtain is dark and you can’t see through it. You step quietly into the room.

A bra hanging on the towel rack draws your attention. The sexiest bra you’ve ever seen. (But it’s impossible to be less sexy than the plain worn bras your wife wears). You lift it up. The underwire cups are massive. It’s made of sheer lace. You’d easily be able to see her nipples while she wears this.

Your little brother’s wife is not conservative at all if she has a bra like this. Did your brother marry a sex freak? How did he get so lucky? A wife with massive tits who wears sexy bras.

You hear movement behind the shower curtain. Probably your brother’s wife soaping up her fat tits. Before you pull back the curtain, you have to find out how big they are.

You run your fingers down the straps of the bra. You find the tag. You have to know the size.
