@Image1 defines QQ’s facial features, long blonde hair, athletic build, fitted black sleeveless top, thin purple thong, white crew socks with black stripes, standing-split selfie pose, black smartphone, and the compact daytime bedroom. Do not use any bystanders or any person other than QQ.
@Image2 defines DD’s facial features, long flowing chestnut-brown hair, defined makeup, tanned skin, curvaceous futanari build, and metallic lime-green spaghetti-strap crop top with gathered high-slit skirt. Do not use its background, lighting, or any other people.

[Stage 1]
Initial state: QQ holds the black smartphone near her face, covering most of it, bent forward in a standing split with one leg extended vertically, purple thong and striped white socks unchanged, recording toward the mirror; the light-wood wardrobe, hanging clothes, white walls, wooden floor, and wire baskets match @Image1; the door to her right is open; no one else is in frame.
Primary event: DD walks in from that open door and comes right up behind QQ.
End state: QQ is still in the same standing split, phone still covering most of her face and aimed at the mirror; DD stands directly behind her, skirt on, nothing yet revealed.

[Stage 2]
Initial state: QQ remains bent in the standing split, phone steady over her face; DD stands behind her in the lime-green two-piece.
Primary event: DD seductively rubs QQ’s round ass with both hands, squeezing and spreading the cheeks so the thin thong shifts against her.
End state: QQ is still in the original pose, chuckling, phone unmoved; DD’s hands rest on QQ’s ass.
DD says in a husky, sultry New Zealand English accent: {Wow, now look at that.}
<QQ’s soft chuckle>

[Stage 3]
Initial state: QQ holds the standing split and the phone; DD stands behind her with both hands just leaving QQ’s ass.
Primary event: DD draws the skirt slit aside, revealing her large erect penis which springs out, grips the shaft, looks toward the mirror, and after every word slaps the head of her penis on QQ’s ass cheeks.
End state: QQ is unchanged in pose and phone position; DD’s skirt is held aside, her erect penis against QQ’s ass, eyes toward the mirror.
DD says more quietly, in the same husky New Zealand English accent, one word to each slap: {Look at that ass.}
<soft wet slaps of the penis head on skin>

[Stage 4]
Initial state: QQ is still in the standing split with the phone covering most of her face; DD stands behind her, skirt aside, large erect penis against QQ’s ass.
Primary event: DD pulls the purple thong aside, lines the head up, and inserts her large erect penis into QQ’s pussy, then thrusts in a steady rhythm; QQ’s ass jiggles, the shaft glistens, and she never breaks the pose or the phone aim.
End state: QQ remains bent in the standing split, phone still pointed at the mirror; DD is behind her, skirt aside, penis buried and still thrusting, thong pulled to the side.

Photorealistic skin, wood, and fabric with high-fidelity natural color, soft daytime window light, sweat sheen and wet shine on skin and the shaft.
Vertical cellphone framing as QQ records it, phone aimed at the mirror so both women stay in view, camera static with no cuts; any tiny phone shift moves the whole view in sync.
<(quiet daytime bedroom tone)>
<wet rhythmic thrusting>
