(Subservient) Dev is going to cum

Dev felt himself edging closer to completion and let Susanne know.

"Ohhhh is my big, strong man almost there? That's not a problem sweetie, you can cum. Let it out, it's okay. Let out all your sweet baby batter for mommy! Let me see how much you've been saving up just for your mommy. Let me see how excited and happy I've made you today." Susanne started jerking him off, her technique mastered to perfection, and increasingly built up her speed and momentum.

Dev was even closer with all the dirty talk from their roleplay (though not so much roleplaying from Susanne's side).

Where did Dev cum?
