[Kame no Misoshiru] My Girlfriend's Older Sister Turned Me Into Her Masochist Foot Pet [edited MTL]

A girlfriend's older sister turns the young man into a trembling foot pet, using teasing, sweat, embarrassment, and escalating commands to blur care, coercion, and desire. Their domestic banter moves from changing clothes and heading toward Ayaka's room to a foot-and-sock ritual, while talk of a promised date adds a teasing social complication. The sequence closes with him on all fours, spent and obedient, as she watches with a cool smile.
