Chapter 3
What does your sister-in-law wear into the hot tub?
A too small bikini top
Your sister-in-law actually asks to borrow your wife’s extra swimsuit. You thank heaven your wife brought a a two-piece as a backup that she never wears. Finally your wife has contributed to something sexy.
After the kids are down, all the adults get into the hot tub and share a bottle of wine. Your little brother and his new wife are the last to join. You make you have a good view of the back door and their entrance.
She wears a robe across the porch for modesty. She turns her back to the group and sets it on a chair. The bottoms fit her just fine. She turns around with her arms paneled over her chest. My wife’s modest bikini top is absolutely stretched by her heavy jugs. She tiptoes to the hot tub. Her massive tits bounce in the tiny top, threatening to escape.
She steps into the water and dips down until her ridiculous cleavage is beneath the water. She moves her arms away even though they couldn’t begin to hide those big ole titties. She brings up the topic that is on everyone’s mind.
“Sorry for the cleavage everybody. Forgot my suit.”
Everyone laughs.
“It’s my fault,” your little brother says. “Totally forgot about the hot tub.”
“It’s because you were always too cool for it,” your younger sister says, “now you gotta hang us with us married losers.”
Your wife raises her glass in a toast, “Cheers to the new family member.”
When your sister-in-law lifts her glass, her tits rise out of the water like a breaching submarine, water pours down their curves. Her cleavage is so deep. You could stuff your head in there. You see where her nipples poke the fabric. Her areola are so close to being exposed. A strong wave could knock them out.
Everyone drinks and you’re still staring. Holy fuck. Where did your brother find this girl and why are you just finding out about her huge rack today?
Your wife nudges you. “It’s rude to stare.”
You laugh nervously, and then say honestly, “Sorry. Just learned some big things about my little brother’s new wife.”
Your wife must be feeling buzzed from her three sips of wine. “I thought you said you were a butt guy, not a boob guy.”
Your little brother overhears and answers the question, “No. I’m the one into nice butts. It’s ironic who we married.”
Your sister-in-law looks back at her husband, “Having you been checking out your brother’s wife’s butt?”
Your brother blushes.
You had no clue that he liked your wife’s ass so much. You wonder how much he checks her out.
Your wife jokes, “I’ll make sure to get out of the tub first so you can watch me leave.”
She’s feeling the wine. It’s going to be an interesting night. You can feel it. That top is coming off.
How does it get interesting?
