You pull off your pants and turn around. With both hands, you spread your butt cheeks apart, showing your mother your pink, puckered anus.
"I think I'll send you to my stomach through the back way, Mom." You say as you lower your asshole onto her head.
"Please, Luke, you can't put me up your butt!" Your mom says, but it's too late to turn back now.(Not that you would anyway.)
With a little bit of pressure, your ass starts to stretch over the crown of her head. Soon, you feel your ring-piece roll over her face.
Once your ass reaches her tits, you dick has swollen to size. Both her boobs enter at once, making a loud "POP". Her massive breasts feel amazing as they fill your lower bowel.
The rest of her slides in quite easily, though you take some time to enjoy feeling her hips and legs enter. Soon, her adorable feet slide in, and her fate is sealed. Your intestines work in reverse to send her up to your stomach. Once she is deposited in your belly, she shoves on the side, and begs to be let out.
"Please Luke! Let me out! Why would you do this to your own mother?"
