Topping up

Mmm, morning lover boy. What? Oh yes they are bigger thanks for noticing. 

Didn't I explain about the spell? Oh, well it's like this, every time a guy cums a in me I use a bit of that energy to enhance my body. So my tits get a bit bigger, my ass gets fuller, my pussy gets wetter and more needy. Heh, a few more sessions like last night and I won't be able to get out of bed!

Unfortunately the effect is only temporary, the energy I took will soon get used up and I'll be back to the sweet little slip of a girl you met the other night. Unless you are willing to keep me topped up? 

That's a good boy...
