There's only one thing she'd change

"Oh honey..." she moans, still clearly strung up from you sucking her hyper sensitive nipples. "you know that you already are perfect to Mommy". You could have predicted that - of course your mom doesn't think you need improvements, despite your obvious faults in the form of your lankiness and muscles. "But if I'd have to choose, and you're not allowed to tell anyone" she continues, giggling, "then I'd rather you'd change to be even more perfect." She shudders as she says that last thing, a wave of horniness flowing through her body, and hugs you tightly to her bossom.

You're not sure what she means. You don't feel changed in any way. It is interesting, though, that your wishes of course compound and therefore change also the answers she would give; Her new nipples, and her willingness to let her suck them didn't just make her appear horny, or agree to act horny - rather, she was, in all actuallity, positively keyed up with sexual desire. But what was that 'more perfect' business about?

You realize the answer to that question at the same time as your mom does.

"Now that Mommy has taken care of you, you better make yourself decent!" your mother says with the authority not of the slut you've just been jerked off by, but with that of a parent. she gestures down to your cock which is still out and which, you had just now noticed, had changed: You realize that the sex-filled state your mom's mind had been in when you asked the question about your body had led her to have cock on the mind, and that manifested in what she considered to be - and indeed, to exhaust the concept of - the perfect body shape.

Your dick is standing tall and hard, despite you having ejaculated just minutes ago, and it is standing massively beyond what it used to be. Some five-and-a-half inches have grown to seven, the girth has increased to approach that of a red bull can and your veins are more pronounced. Most notably though, pre-cum has begun to accumulate around its tip despite your recent ejaculation - it feels like you could cum again right away, and more than that: it feels like jizz is already pushing itself out of your urethra. You can't be sure what exactly the specifications were that your mom had in mind when she answered your question, but one thing that it seems she is very much so into is the ability to produce massive amounts of cum. Dirty slut, you think.

"Okay" you say out loud, covering your dick with your boxers as she'd asked and immidiately staining it with jizzm. "time for a more difficult question"
