Umbra and You go to the same gym and she likes chatting with you and showing her progress to gain a bit of praise it helps her stay motivated.

Today you walk into the corner where some bags, weight and other agility equipment are nearby and as you almost wanted to begin Umbra patted your shoulder with a friendly grin.

Umbra:"Heyyy dude, I was waitin' for ya i wanted to show my torso look how cool i look!" she lifted her tank top almost flashing her breasts but she didn't care as long as you you sas her soft but slightly visible abs.
