So the smoothie you drank says it should make your cum have special magical properties that will cause my tits to increase a cup size or two. I am so excited! I love tits and would love mine to be bigger.... bigger is of course better! You stroke for me as I talk about how excited I am to try this.... and when you get ready to cum I bend down and swallow it all! Listen to me gulp.... you cum SO MUCH! As I react to how much I swallowed it starts to feel hot in the room.... and then... BAM! My tits expand as you blink. And this is MUCH MORE than a cup size...... WOW! Maybe its because I swallowed so much of your cum!?!? I am in shock but totally in love with these big tits! I notice you are loving them too and already stroking again! How could you get so hard after cumming so much!? I encourage you and am excited to see if your cum will still be magical the second time..... you tell me you are about to cum and so I get down and GULP GULP GULP! WOW... SO MUCH CUM... even more than the first time! Then... within a blink of your eyes my tits expand even more! I am in shock yet so happy! Your cum mixed with the smoothie you drank has caused some seriously awesome HUGE TITS! Maybe they are getting bigger than a small cup size due to how much you are cumming and how much I am gulping down!? As I talk about them and show them off you begin to stroke again.... I am unsure if we should do more but you are already almost to cum so I don't let it go to waste and GULP GULP GULP! Within a moment, you blink and BAM my huge tits expand even bigger!!!! THIS IS INSANE! These things are HUGE! You get hard again staring at my massive tits! You can hear my skin squeaking the tits are expanded so much! I am scared to swallow anymore as I am scared my tits will burst.... BUT i would love to share your magic cum with my girlfriends......! So I encourage you to cum in the bottle so that I can share your magic cum with my friends and then go out on the town with all my big tittied friends and you can show us off!
