Seamless tight loop. Frieren remains COMPLETELY STATIC and MOTIONLESS in every way, head thrown back, chin up, static, very long white ponytail hanging static, pointy ears static, green eyes static, blush static, red sheer lace lingerie static, red bra static, red thong static, red garter belt static, red thighhighs static, her standing leg static, foot planted on the floor, her raised leg static, knee up, foot braced on his thigh and staying exactly there, her hand on his chest static, her back against the wall static, his hand in her hair static, EVERY SINGLE ELEMENT LOCKED FROZEN. His legs are locked rigid — his knees do not bend, his thighs do not move, his feet do not move, his stance never changes. His body stays exactly where it is. The only thing in the frame that moves is his hips. Only his hips move, in a dead straight line — no arc, no rotation — straight along his shaft and down her throat. His cock is rigid and does not bend, it only slides along the line it already sits on. He is already buried in her mouth on the first frame and he never comes out — not on any stroke, and not at the end. The entire motion lives inside one tiny range and nowhere else, from the depth of this first frame to balls deep, and back. He never comes back further than the depth of this first frame — not a fraction further — and the instant he touches it he is already slamming back in to the base. At the base his balls are flat against her lips and her nose is pressed into his pubic hair, her throat bulging. Her lips stay sealed and stretched around his shaft the whole time. The head of his cock is never once seen. No pause, no hold, no mercy — hard, fast, short, tight. His balls stay low and small. Every slam identical. The first frame and the last frame are identical — he finishes exactly as deep as he started. Drool drips from her static mouth. Frieren takes the destruction completely motionless, unblinking. Perfect seamless loop.
