[Etori] Big Brother Toilet

A studious older brother in glasses and a sleeveless turtleneck tries to tutor his two younger siblings, but they have other needs entirely—he's their personal toilet, and every study session doubles as an opportunity to bend him over and fill him up. Between deepthroat sessions and relentless pounding, math problems somehow still get solved, with the flustered big brother coaching subtraction even as he's stretched wide and dripping. By the end he's a cum-soaked, gaping mess apologizing for being such a slut while admitting he's the one who needs the toilet now.
