[F4M] Your Brother's Pregnant Wife Is A Pent Up Mess

NSFWRP/Conversation

The whole family was ecstatic when they announced she was pregnant. They'd been college sweethearts and after college quickly got married and did their traveling. They were ready to settle down. Your brother was excited to be a dad and even invited you to stay with them while you looked for a job, because he knew his wife could use the companionship with him usually away on business. Free rent, a huge house full of amenities and you just had to keep your sister-in-law happy? Should've been a walk in the park.

The first few months were brutal. Your brother was overseas and you were there rubbing her back and pulling back her hair as she fought back morning sickness at all times of the day. He was going partying with work colleagues while she was struggling through the discomfort and agony of her body rapidly changing. When she entered her second trimester, you thought things would get easier, and then her stomach growled.

She'd warned you about the women of her family. How They'd each turned into swollen heifers dedicated to being round and proud. You couldn't stop gawking as the once proud prom queen was raiding the fridge throughout the day and never seemed to stop eating, naturally blaming the baby for her ravenous behavior.

Your brother came home for a bit as she hit five months, and couldn't believe how thick and pregnant she'd become. Her ass seemed to get wider by the day, you could see her dark areolas through her tops, and her belly was this prominent fixture that turned heads anywhere she went. She was elated to have her man back, but instead of satisfying her growing urges, he looked for any excuse to fly back out to their international branch.

You hated seeing her writhing in discomfort. You were ashamed you listened in when she used her toy in her room and couldn't resist trying to sneak a peek until you heard your name drip from her lips as she came violently on her own fingers. She needed relief, she was eating her feelings and desperate for any kind of companionship. Could you hold yourself back? Could you resist?

She's round, getting rounder, and craving more and more with each day. Doesn't have to be this particular scenario, but I'd love to do a pampered pregnancy roleplay where they just completely give in to their rawest desires. Would love a focus on pregnancy and the symptoms that come with it. We can also include weight gain, but I know that isn't for everyone.

Other role options: (If you have your own, don't hesitate to share!)

  1. Your sister's best friend is pregnant and staying with her when you go to visit for the holidays. Your childhood crush now desperate for you to cover her bump in your seed now that you're a success.

  2. Fat assed pregnant secretary teases and taunts you when she catches you staring at her belly and keeps pushing you until you finally act on your desires.

  3. Pregnant neighbor struggles with her cravings and can't seem to find anyone to help. She tries to keep it together, but you catch her playing with herself on her deck one day and know it's only a matter of time before she says something.

  4. Your girlfriend's mom is pregnant and you can't stop gawking as you help her out around the house and she's eager to repay your kindness in ways her lawyer daughter never could.

  5. Pregnant patient keeps flirting with her doctor and keeps pushing him until he's stirring up her insides while her legs shudder in their stirrups.

  6. Pregnant former cheerleader let's you tear into her fat ass at a class reunion as a way to apologize for her baby daddy being a former bully of yours. Only problem is you both end up hooked on the sensation and keep coming back for more.

I prefer third person, but I'd love to set something up if anyone is interested! Have a beautiful day and stay safe.
