Your Sister's Taboo Kinky Experiment

I am always looking to push my body to the limits. Including when it comes to sex.. So, when I found an Ad for this magic tea that can make cocks huge.. I had to buy it! However, who would I test this on? Well my brother of course!! While making his tea I get carried away. I end up using the whole pack! And in less than 30min my brother's cock was already so huge and it wasn't even at it's peek yet! His cock was so huge and beautiful- I couldn't help but fall to my knees and start sucking.. And it got bigger.. and bigger.. and BIGGER. I couldn't wait any longer! I needed his cock in me! NOW. I needed to be on top so I could get his huge cock as deep in me as possible. I could feel his cock growing inside me. It went to my stomach.. Then to my throat.. Until I was throating his cock from the inside. His cum oozing out of my mouth! I couldn't believe the tea worked! I need to buy more NOW. Maybe two packs?.. Three?
