I fantasize about Big Fat Cocks Virtual Sex

So the fantasy is basically that you would play the girlfriend of a guy with a somewhat smaller-end-of average cock, and you’ve only ever been with him. You’d basically say in the middle of a virtual sex scene (most of the scene is virtual sex in various positions) that you have something to confess. You’ve never thought size mattered but you’ve recently been talking with your girlfriends and felt kind of jealous that they all brag about how big and fat their boyfriend’s cocks are. You say that you didn’t believe them or didn’t think it would be much different than your boyfriend’s until they showed you a picture. They told you about how good it feels to have your pussy stretched by a cock that’s big and fat, and how filled up you can feel with a cock that big, and how fun dirty talking is when your impressed by how manly his fat dick is. You explain that you still like his cock and can cum, but you’d like to explore fantasizing about bigger cocks while having sex because you’ve discovered that you cum much harder when just thinking about big cocks. Major emphasis on the phrases “fat”, “big fat cock”, and things like “stretching pussy”, “stretching me out”, and describing your pussy as little and tight. You could borderline spam “big fat cock”. The idea is that you start pretending that the boyfriend has a big fat cock and you want to dirty talk to him in that kind of way, telling him it’s big and stretching your pussy, but it isn’t believable because he isn’t really stretching your pussy and it feels too small to get the big dick step-daddy treatment believably so you start to dirty talk and wish his was really bigger. Maybe some phrases like “It would be SO nice if you had a big cock, don’t you think? Wouldn’t you like that too? Don’t you wish you had a fat cock? You’d probably love being long enough to fill my entire pussy up and having a cock fat enough to feel my pussy so tight around it, so big and fat, just stretching me to my limit. Youd love having a huge dick, just thinking about how much more I’d love having sex with you if you really had a huge fat cock makes me wet. You’d come home and I’d just want to pull your boxers down just to see that huge dick and big fat balls and feel you stuff it slowly inside my little pussy”. Riff on that until the point that you cum while riding him while thinking about the big fat cocks and wishing he had one, how it’d make you cum harder, etc. Kind of humiliating but with a more light and loving tone, with your arousal clearly growing the more you fantasize about the bigger cock. Similar in tone to your small penis humiliation sex video, kind of friendly and loving and still aroused and sexy but with a humiliating air of being compared to an ideal of the girlfriend’s bigger dream cock. Also, slowing down and putting a lot of lusty emphasis on the word fat, just like how you say it in the stepbrobj
