She then presses your little body against the denim, near the midle of the pocket. You are being pressed so hard, you are drowning in the fabric. "You're nothing compared to the back pocke of my jeans", she says, then slips you up to the lip of the pocket.
"In you go, slave", she laughs as she slips you down into the back pocket. Your world becomes dark and nothing but denim. She pokes you down as far as she can, then lifts her ass from the bench a little, so she can poke you down all the way to the bottom of the pocket, where the seams meet in a V-shape.
She lets you go so now you squirm at the juncture where the seams meet for a second, then Goddess Barbara lowers her ass back down to the bench. She moans with pleasure as she feels the little bump in her back pocket flatten under her ass. You are squished flat inside her back pocket.
