[Seto Ryouko] Yuki no Furu Koro [mysterymeat3]

A snowy evening brings the elegant, glasses-wearing tutor Yuki-san to his student Touya's doorstep, where a mother obliviously welcomes the guest for what should be another quiet study session. One accidental bump of knees beneath the low table ignites the tension, and soon the delicate tomgirl is riding his blushing tutee through breathless anal intercourse, sweat dripping and lenses fogging as he begs for breaks he never actually takes, then takes it from behind until they both collapse in a slick, overwhelming finish. A bonus epilogue catches Touya afterward, flustered and grateful, wondering whether blowjobs from your tutor are simply normal for college students.
