you were already doing it before she asked

So far you’ve had 8 orgasms and you haven't ran out of semen yet. You begin to wonder if there were any other enhancements to her sperm that were added on for free. As you think this you begin feeling over your changing body and notice a few things. For one, your balls are definitely much larger than before, your borderline useless cock is still the same which is fine by you; you are not gonna use it much anyways. You notice your hips are widening and ass is growing too. As for your asshole you can tell it’s changing too since it no longer serves its use as an exit, it’s turning into something purely for pleasure and is taking on more of a donut like look to it.
