Take note of their expressions. Does the girl look like she's having fun? No? That's because she already knows what's going on. Suddenly, he's less interested in "painting with light" and keeps on asking how she wants her "trophy" unlocked. She will probably remind him that their relationship is strictly professional, but that won't stop our favorite old man. What happens next is up to your imagination.(Bear in mind that graphic depiction of RG in any sexual act can and will leave horrific mental scars. View at your own discretion.)
Remember ladies, if you don't want to be left with your panties in a twist, avoid this scenario AT ALL COSTS!
