Digesting the first load

While riding her cock, your pleasure is so great that you can only fit one thought in your head: deeper. You pound her cock deeper and deeper into your slutty hole with every bounce, not noticing the swell of your belly go down. At this point you can't think about it anyway. All you can do is ride as hard as you can, sending her gargantuan cock ever deeper into you.

As you bounce like a slut possessed, Ashley gets a better view of your changes. She watches as her slut's body slowly absorbs her first load. Your belly slowly shrinking as your body absorbs it, rewriting your very DNA to fit her needs. A few minutes into the transformation and your shoulders have lost an inch in width that seem to have gone directly to your hips, with more transfering every second. All the mass from the load in your belly has been adding extra jiggle to your ass with every bounce you take, still perfectly oblivious to your changes.

Your mistress smiles as she feels her next load building. If the first load set the course, what will the next load bring?
