Not well

Emma popped her mouth off your dick, "oh yeah! Lily, do you want me to make him cum on your face?"

"Yeah, okay."

Emma wrapped her hand around your cock and pointed it at Lily's face. As she jerked your cock, she coached Lily, "close your eyes and open your mouth. It's hot when you taste it too," she looked at you, "right?"

"Fuck yes," you confirmed. Feeling Emma's hand around your cock and looked down at Lily eagerly waiting for your cum was too much. You warned the girls, "I'm going to cum."

As the first rope splashed across Lily, you realized Emma didn't have much experience aiming a cumshot. When it hit Lily's closed eye, both girls yelled, "oh!"

In her surprise, Lily opened her other eye to see what was going on, but Emma overcorrected and the next spurt of cum hit her open eye. Lily closed her eye and yelled, "aaaah!" Emma realized she was in over her head, let go of your cock and jumped back, "oh my god!"

Your freed cock sent another rope of cum onto Lily's forehead and into her hair. You took control and sent the last of your load with more control onto Lily's mouth and down onto her chest.

Emma was in shock, "oh my god Lily, I'm so sorry!"

Looking down at Lily, she was covered with tears and spit from her deepthroat attempts. She was completely covered with cum on top of that. You wanted to feel bad about seeing her in distress. You didn't want to think it was hot. But holy shit it was hot.

Lily had a different opinion about the situation. She had her eyes squeezed shut and waved her hands in panic, "aaaaaah!"

Emma grabbed her hand, "it's okay, Lily," and after a moment to take in the situation stifled a laugh. "I didn't..." she snorted, "I didn't know it would be so hard to aim!"

"Aaaaaaah!" countered Lily.

Emma grabbed both of her hands and pulled Lily to her feet, "I'll..." she laughed openly, "I'll take you to the bathroom."

"Shut up! Aaaaah!" Lily yelled, but was obviously now trying not to laugh herself.

After a moment, you followed the girls into the bathroom. Emma had wiped the worst of the mess off Lily's face. There was still a line of cum streaking her hair.

You wrapped your hands around her waist and looked down into her eyes, "are you okay, Lily?"

"Yes," she said with only superficial anger.

"I'm sorry I", you laughed, "I didn't know it was so hard to aim either."

She grunted and said, "I hope it felt good at least."

"You won't be happy about it but... that was one of the hottest things I've ever seen."

She grunted again, and stomped off to the shower.
