A son who is allowed to masturbate freely but instead finds himself constantly managed by his younger stepmother when it comes to ejaculation. Today, he was made to endure having his mother's pussy licked against his wishes or have her mouth wrapped around his cock while she teases him until he can't help but get hard. Despite not wanting any of this, he feels trapped inside her tight snatch, knowing that he'll eventually be forced to cum inside her through creampie.

勝手にオナニーをすることを許されず、年下の義母から日々射精管理をされている息子。この日も義母の勝手な都合でマ●コを舐めさせられたり、ペニスを咥えられ寸止めされたりしてしまう。その気が無くてもずーっとチ●ポを責められれば自然と勃起してしまい、義母のキツキツの膣穴で締め付けられて中出し射精を誘発されるのだった。
