"And I'm one of them..."

What? No, that's -!

Mommy's hand on the back of your head gently pushes you into her crotch as, to your great astonishment, her butthole stretches, little by little, and prepares to devour you. First your nose is buried inside it, then your cheeks, forehead, chin...

when finally up to your ears inside, the rest of your head quickly slips in, and your mother's sphincter closes immediately around your neck, making a loud, sucking noise. You wiggle around and try desperately to pull out, but it's hopeless. You're stuck in your mother's butt.

It's tight, cramped and moist, but also strangely cozy.

When she speaks, her voice sounds muffled to you, but you feel strong vibrations all around with every word.

"Oh, yes!" She moans, "It's been too long since I felt this! I used to do this to your father all the time when we were having an argument, but that was a long time ago. I needed this."

Your mother flexes her anal muscles a bit, massaging your head. As her balls, resting on your neck, begin to move up and down, you realize she's masturbating, using her son's head as an anal plug.

"Baby? Do me a favor and struggle, it just feels so good."

You comply, shaking your head and pushing away as frantically as you can. Her vice grip is unshakable, but you hear (and feel) her moans of pleasure, and the pace of her hands going up and down her cock increasing rapidly.

Following a loud, satisfied moan from your mommy, her body rumbles around you and several long strings of warm, thick cum land on your naked back. You feel her breathing slow down to normal.

"Oh honey, that was amazing... I'll push you out in a moment, just let me lie down and rest first."
