Awwww... all blissed out, cradled by her Mistress... I think somebody just took the first steps to surrender and doesn't know... and doesn't care ;-) Love both their expressions in the last panel. Nicely done :-)
I think it happened around the time the hips popped out.
Honestly I think that page (V1P12) would benefit a lot from being redone. It has a clashing art style compared to the rest of the comic, misses out on an opportunity to show her thighs and ass coming in, and his pants somehow manage to stay on despite having just shrunk dramatically and then suddenly start slipping off after the hips expanded. They should've been around the knees almost immediately IMO.
I love how Mistress Vallochar is holding Allison to her... which lets her share the pleasure to some extent, and even as she cries out her joy, shows Allison her place and that she's only having this moment of joy because she's being allowed to ;-) Love Allison's expression by the way... talk about over the top orgasm :D
Love all the different kinds of fantasy as her repressed libido gets the better of her :-) Even she doesn't really know which she prefers... to be penetrated, or be the penetrator ;-)
I *love* how she's collapsed in Mistresses lap, but doesn't seem to care at all... so lost to the pleasure. And the knowing smirk on Mistresses face... hehehe... priceless :-)
Okay, first, these last two panels are very hot... but I can't help but wonder if perhaps Mistresses won't quite let her go all the way and experience her orgasm in this new form. And if she does... I wonder just how far out of 'control' Alison will get... hehehe ;-)
