Setting up to arist
Panel 1: ichika sex with her leg up. Have an xray overlay such that in the cock reference. Cum shooting inside her.
The perspective in the references are fine, no need to show more of his body.
Panel 2: titjob, cock is much larger then in the sex pic, it's the size in the xray. It's a cum fountain. Spraying all over her tits and face.
