[S-Size (Shinachiku)] Boku no Tokutouseki [Hikaru Scans]

A boy claims his special seat right next to Sou-chan on the train ride home and turns the commute into his own private show—slow, shameless strokes and teasing nipple play while his flustered classmate squirms beside him, insisting he isn't watching. Breathless confessions that his hips feel 'all floaty' and whispered dares to hurry up and finish keep the tension thick between them, with nothing more than hands and heat passing back and forth. Later, tangled together on a bed, the bravado melts into something tender as one of them quietly admits he's glad this was the reason.
