I have an idea of roleplay in the form of a mother and her 18 college-aged son texting. I'd be happy to swap characters to daddy/daughter as well! Let me know if you like it:

Your husband is never helpful in this department. Your daughter is usually the one you’d ask about outfits and swimsuits for your friend’s upcoming bachelorette party/trip, but she’s going through her rebellious stage and is as talkative as usual. You can’t ask your friends either since their the one’s you’re competing against to be the best dress and have the sexiest outfits. You love them but there’s always that edge of competition. It’s just how you all are.

As a last resort, you text your son asking his opinion on some outfits, and he actually turns out to be really helpful, enthusiastic even. You get a little nervous moving from blouses and slacks and dresses to swimwear, but it gets interesting when he keeps picking the most revealing bikinis and asking for pics of you trying them on. You start looking forward to shopping so you can send him pics and get that adoring praise from him. You find yourself texting him more and more, wanting to please him by wearing what he likes, and looking forward to texting him before bed every night.

The conversations organically become about what he finds sexy. You ask about dating and girls and what he likes/dislikes. We become playful and flirty, and you start looking forward to the next weekend he spends at home so you can try on outfits for him in person.

Where does it go? Do you send me pics in lingerie asking if my dad will like it? Do you FaceTime me while trying on bikinis and “accidentally” leave the camera on when taking them off? Do you start asking or sharing more intimate thoughts and feelings, reminiscing on your wild college days, and talking about fantasies? What if you accidentally send me a nude? Or I accidentally send you a dick pic?

The buildup could be great, but I'm also so excited for moments like when a mother sucks her son and tastes his cum for the first time.

I really just love exploring the dynamics of this taboo mother/son relationship that builds from something innocent to something that's not that bad to deepthroating your son while I'm home for the weekend while the rest of the family is asleep.

I look forward to hearing from you :)
