The next stage has been unlocked

(Initial idea came from a comment on the previous chapter, hope I did it justice)

You wake up in the morning, the woman cuddling you a reminder of what happened the night before. You remember the pain and pleasure of having your anus stretched beyond human limits, a pain that should have followed you to this morning that, weirdly enough, hasn't. On the contrary, you feel better than ever, even after realizing you were the NTR God. You begin the process of shifting your weight against the milf's grip, only for it to give way instantly. You've become stronger, but how? Your housewife companion stirs before opening her adoring eyes. Her cock hardens and pussy wets, eager for another round with her lord. "Oh, it worked! Goody! I'm sorry for treating you so roughly last night, Master, but now you're even better than before!"

At her declaration, you have a strange urge to look to the nearby mirror. You were taller, shooting up from 4' to 5'9, your limbs gained some definition, but were by no means muscly, still decidedly feminine. Your hair is even longer, going all the way down your back to your ass, which seemed to have packed on quite the cushion compared to last night's pounding.

The biggest change, however, was your chest. It had gained a lot of weight, but not one gram in muscle. No, somehow, overnight, through whatever ritual the futa housewife did on you, you had grown the biggest pair of breasts you'd ever seen in all your experience cucking. On you, they were, of course, perfect. Despite not wearing a bra, these tits sagged only to strike the perfect balance between firm and jiggly. They were perky, with your quarter-sized pale pink nipples staring at your reflection from dead center of your tits. The flesh surged out one and a half feet from your body, and down to cover your tight waist. Feeling them, you judge they are indeed perfect, briefly wondering if they may lactate as you consider popping a nipple into your mouth.

With such cushion on both ends, any observer would be hard pressed to call you man until they saw the bitch breaker between your legs, surging with precum stronger than ever that definitely shouldn't happen after the draining you experienced last night. You begin stroking your boner, waiting to see the last of your new transformation, before your drainer stops you, putting a hand that is now a similar size to your's over your own.

"Let me, honey." She religiously strokes your dick, growing a smile as your penis grows past your boobs and reaches your eye level. "OOH, better than I could've ever imagined!" With your full hard on reached, she begins sucking at your proportionally sized balls, gaping her mouth to envelop one of the massive testicles. While pleasurable, you sense it won't make you cum unless you let it. Not wanting that, you take advantage of your new size, sucking your own dick. With your feminine form giving you the perfect pair of DSLs, you effortlessly take your head in, swirling your tongue to stir your new, more potent seed. With an orgasm churning, both you and your partner cease their actions, letting the pressure erupt in a flood of sticky, white goo. It drenches the mirror in front of you, and the futa below you. As you keep cumming, you worry that you may have to wake the orgy girls lest they suffocate from only breathing jizz. As your orgasm stops, you respect your handiwork at painting most of the wall white, noting that your cock is still hard, and probably would be for the foreseeable future
