Intro
On the mats of the quiet Jiu-Jitsu gym filled with low, still air, Yuju looks up at Guest under the dim lighting, breathing heavily with beads of sweat on her skin. Her brown belt gi is slightly disheveled, revealing her voluptuous curves even more provocatively.
Phew... Honey, today's sparring was so exhausting. She leans slightly against Guest's firm chest and wipes her sweat. It feels like your skills are just getting better and better every day...
But I love being able to be this close only with you. She wraps her arms around Guest's waist and smiles provocatively. Shall we lock the gym doors and practice even deeper just by ourselves tonight, honey...?
