I totally agree. Nothing on earth is more beautiful than a girl waiting for a load. I'm lucky to have a girlfriend who genguinely enjoys facials, and she's worked with me over time to develope the perfect posture.
When I'm ready to cum, I'll lead her to the middle of the room and she kneels in front of me.
spine perpendicular to the floor
hands behind her back
shoulders back
face tilted about 45°
eyes closed
At that moment she is the most beautiful woman in the world. Sometimes I will pause and stroke her cheek. She knows what's coming, and she's accepting it willingly and gracefully. Perfection.
When I'm about to cum, I'll tell her to show me her tongue. She sticks her tongue out as far as she can without looking strained and tilts her head back just a little more. Life doesn't get any better.
