Debriefing and… de-brief-ing.

"So... about your mom..." Ava starts, having regained her breath.

"She definitely changed, I--" you start, but Ava shushes you.

"I know, I could... sort of tell? A little? It's, like, I got an echo of your mom with smaller breasts, which is weird, since I also remember her always having those enormous breasts of hers, and always milking herself..."

"Huh." Another mystery to solve, on top of the mystery of the choice to start with.

Ava laughs. "You make the funniest faces when you're thinking, string bean."

"Rude!" You both laugh into each other's arms, still snuggling on the bed.

You both lie there for a little bit, just soaking up each other's presence, and marveling at how lucky you are to have found each other.

Then, in her sexiest voice, she purrs into your ear: "By the way, stud, just because you got me off already doesn't mean I don't still want that big, sexy cock of yours inside me." She starts gently stroking your cock, teasing her fingers up and down your shaft.

You squirm a little under her touch. "I don't know if that's such a good idea... we still don't know how things change--"

"--and we're never going to find out more unless we keep experimenting," she finishes for you, kissing you afterward to silence your objections. Unable to muster any further objections, or any other thoughts beyond sexy girlfriend wants to fuck, you and Ava keep making out, peeling off her clothes as you go.

At some point, she must have slipped a second condom out of your bedside table, tearing it open with her teeth and sliding it onto your cock. "Alright, stud, we're all set," she says, and you can tell from how soaking wet she is that she really means it.

You've positioned above her now, and without any further ado you slide into your girlfriend, your long torso pressing up against her shorter, sexy body.

As the two of you begin fucking away, you try to take a moment to compare this to the sex you had with your mother just a short time ago. Your mom's body was enormous, almost overwhelming in scale -- so big, so heavy! -- and her breasts dominated sex with her, filling your vision.

Ava, on the other hand, was the complete opposite. You were easily over a foot taller than her, which makes you feel like some sort of giant fucking a beautiful little pixie. Her breasts bounce perkily, small only in comparison to the enormous udders your mother's packing. You briefly imagine what Ava would look like inflated to match her prodigious lactation, or like the police woman, before being pulled back into the present moment by an insistent sensation in your cock.

"I'm close! What should I pick?" You manage to say as you feel an orgasm building up.

"Mmm, fuck, you choose, stud!" She cries out, between thrusts.

You pick up the pace, and as the two of your groan out in nigh-simultaneous peaks, the world stops around you, and the question echoes in your mind again, just as before:
