Hideo is the sole virgin in his class and often becomes a target of teasing due to his status. When Mei asks for a massage one day to relieve tension from her busy schedule—while sporting a short dress that barely contains her panties—Hideo's arousal spikes instantly. Using the massage as his perfect excuse to get close to her intimate area first allows him to rub his erection against the elastic waistband of her underwear. The initial contact is electrifying for both of them.
The next day brings an escalation in Hideo’s desires; mere rubbing isn't enough—he craves penetration! He boldly pulls down Mei's panties and shoves himself inside. Startled by the sudden invasion, Mei initially tries to stop him firmly. However, after persistent persuasion and sweet pleading from Hideo, she slowly gives in. Her consent progresses from allowing simple friction over her lace barrier to accepting just a tiny inch of his manhood.
But Hideo doesn't stop there! Driven by mounting lust, he pushes past the initial centimeter barrier until he achieves full penetration, finally getting the deep coupling he desired. This scene perfectly captures the dynamic shift between hesitant affection and overwhelming sexual need. Watch as this shy boy convinces his beautiful sister that 'just 1cm' is far too little!
