You try to get deeper into the dildo but someone is visiting.

[[ English is not my native language and some of the text is translated ]]

You don't waste another second. Your fingers dig into the silicone walls of the dildo's hollow shaft as you pull yourself deeper, twisting your body to wedge your shoulders into the narrow passage. The texture is slick - a combination of the silicone's natural smoothness and the residual warmth from Hannah's earlier handling. You grunt, pushing with your legs against the ridges inside the shaft, slowly inching your way deeper into the curved interior.

The dildo suddenly lurches, and you hear it - muffled, from somewhere outside. A voice. Not your mother's.

"Hey babe, I'm back from my jog!"

Clara. Your mother's lover. You've met her a few times - she's a fitness instructor, tall and lean, with short brown hair and an easy laugh. Your mother has been seeing her for about a year now.

You press yourself flat against the inner wall of the shaft, breathing hard. From your position deeper in the dildo, you can barely see through the tip anymore - just a blurred circle of light and vague shapes. But you can hear, albeit muffled, as if listening through a wall.

"Hmm, perfect timing," Hannah's voice comes through, warm and playful. "Want to join me?"

Clara laughs. "Looks like you started without me. Where's the strap-on harness for the dog dildo?"

Your blood runs cold. The dog dildo. The one you're inside of. The one with the knot. The one connected to a reservoir full of your mother's cum.

There's movement - the dildo shifts, and you feel yourself tumbling slightly as it's picked up. You grip the walls tighter, your wedge holding for now. You hear the sound of fabric rustling, a zipper, the soft sounds of someone undressing. Then a click - the dildo being attached to something rigid. The harness. Clara is strapping you on.

The dildo is now held upright and rigid, the base secured against Clara's body. You can feel the subtle pressure of the harness straps pulling the silicone taut around you. The reservoir hangs below, swaying slightly with Clara's movements, the warm fluid sloshing faintly.

"Hands and knees, babe," Clara says, her voice slightly muffled but clear enough. "I want to take you from behind."

You hear the bedsprings creak as Hannah moves. Through the blurred tip of the dildo, you can make out vague shapes - the pale form of your mother positioning herself on the bed, her dark hair falling forward as she settles on her hands and knees.

"Wait - let me get something," Hannah says. There's the sound of a drawer opening, the crinkle of plastic packaging. A condom. She's rolling it over her own cock to keep from making a mess. You remember - she has both. Cock and pussy. And right now, Clara is positioning the tip of the dildo - the tip you're behind - right at the entrance to Hannah's pussy.

[OUTSIDE]

Clara runs her hands over Hannah's wide hips, admiring the view. Hannah's plump ass is raised in the air, her back arched, her D-cup breasts swaying beneath her. Between her legs, her semi-hard cock hangs, already sheathed in a condom that catches the morning light from the window. Below it, her pussy glistens with arousal, the pink lips slightly parted and ready.

"Ready?" Clara asks, gripping the harness with one hand and guiding the dildo's tip to Hannah's entrance.

"Just go slow at first," Hannah breathes, looking back over her shoulder. Her blue eyes are half-lidded with desire.
