The kind of power I need 🤩😈
He didn’t just get carried away with his new power - he’s 100% addicted to growing and making other men worship his superior dick! How far do you think he should take it? 😉

It makes sense to have planets on my socks. It won't be long until they're to scale 😏

Remember to get you-uuh-you're God's Nectar at your local s-s-store, and you too can be b-b-BIG like your hero. Ugh...guys, I'm still growing, and--mmmm--and I'm gonna end up giving out free samples if you know what I'm saying

size theft via kissing is really hot, especially when the person who's shrinking realizes what's happening but they're already too weak to get away. All they can do is squirm while they're held in place or pinned down as the thief goes in for another smooch...

Cutting really doesn't carry the same horny energy to me as bulking, but I'm determined to keep pushing it, so that the bulk can really take off.

I want to feel dizzy with lust at the speed of my future muscle growth. To see myself growing overnight and cum just from flexing in the mirror 😈

You thought it was weird your D&D group booked the campus gym for the session until they actually cast size theft and the scrawny guys around the table started swelling muscles with every roll of the dice while you start to feel weaker and weaker...
