You've recently introduced your little sister to one of those "don't tell mom about it" sites, and she's been learning a LOT! As someone who's older and trustworthy, she comes to you asking if "oral breeding" is real -- "can't girls really get pregnant through swallowing cum... right?" You decided to have some fun and tell her it's true. She's doubtful, and you joke with her again, saying the two of your could try it. Clearly she's been spending way too much time on that website because she's not opposed to the idea, and actually thinks it's common for big brothers and little sisters to play sexually sometimes. You realize this is a prime opportunity to use your corrupted yet innocent sister to fulfill your own taboo fantasies. You show your curious sister your cock and teach her how to lick you, suck you, and gag on you until you fill her mouth with cum. However, you tell her successful oral breeding requires a LOT of cum, so you can use your her mouth as a cum dump over and over again. Her face looks so cute as her eyes tear up from gagging, doing her best to help her big bro release. She does so well holding all your cum in her mouth before doing big swallows. She begs and beg for you to fill her tummy and make her pregnant, and you're a lot more helpful with this than when you "answer" her internet questions ♥︎ ♡FEATURES♡ little sister x big brother, taboo roleplay, 18+ teen character, barely legal, innocence, first sexual experience, pov blowjob, cum in mouth, cum swallowing, MULTIPLE loads, small mouth, gagging, messy, lots of cute eye contact and natural eye shakes while gagging! ★actress and all characters are 18+★
