This was made as a custom video.* I’m your younger sister who feels that puberty seemed to only give me a cursory glance. Other girls at school are maturing faster and/or how all the girls your brother brings home are so hot. I decide to kickstart it by taking some pills I got from the internet. I’m nervous about taking them, but I push through. I wake up somewhat groggily, finding myself with massive boobs and an irresistible tingling in my panties. I can’t keep my hands off my fat, inflated boobs, squishing and rubbing them. Eventually a hand travels down and explores my wet pussy, rubbing myself as I explore my assets. The pills seems to have worked almost too well. My breasts have swollen to an obscene size and my sex drive is through the roof. But the rest of me has stayed pretty young. The only cock near at hand is my older, handsome brother's massive dick. I’m sure he will try, but won't be able to resist me. So, I bounce into my brother’s room and quickly tell him what happened. Absentmindedly I start rubbing myself again while talking about the pills and my worries that it not only changed my boobs, but also my feelings. I ask him what he thinks: Am I freaky or sexy? I push my boobs into his face and tell him to feel them to see if anything is wrong with them. To my surprise, his touch makes me crazy! He’s speechless, but his hard cock tenting his shorts speaks volumes. I can’t resist. I have to touch his massive thingy. I love it, practically worship it. I start jacking him off, rubbing against my inflated boobs. Then I try to start sucking him off. At first my big boobs get in the way. Then I realize he’s so big he barely fits. I push out your cheeks, really trying to stuff his big brother cock in while jacking him off. I talk dirty to him, just like I’ve heard his girlfriends do. I ask him if he loves my new, inflated boobies. My bloated breasts and your face struggling to suck him down are too much and he releases a massive load, filling your mouth and splashing my face and chest. His cum feels so good on me and there’s just so much. Then you notice he’s still hard. So, I ask if he’d be up for more.
