[Namakoinu] Kuchi dake wa Yuutousei [mysterymeat3]

A prim honor student with a perfect record discovers his real talent is his mouth when a smug older man pins him down and forces him to tongue-clean every filthy inch of cock, gagging and protesting the whole way. What begins as one man's degrading oral lesson swells into a full group pinning the boy down, raising his ass in the air for relentless deepthroat pounding and anal drilling while he sobs, leaks, and begs them to stop through tears. With a '100' scrawled across his bare cheek and an A+ paper clenched in his teeth, his straight-laced reputation never stood a chance.
