Their gag reflex

You woke up to a sound that could only be described as "unnatural". You walked out to the living room to find both Emma and Lily, looking like they had had a rough afternoon, tears streaming down their faces. What was happening? Had some spell finally snapped and they were upset?

"Are you two okay?" you asked.

They looked at each other an broke into laughter. "We must look like crazy people," laughed Lily.

"So... what's going on?"

Lily answered, "we were talking about something we saw in the videos we had watched. A lot of the girls could..."

Emma finished her sentence, "they could deep throat. We thought it looked really cool, and thought you'd like it if we could do it. You would, right?"

There was no other answer, "yes, yes I would."

"We found, like, a tutorial online. We were trying it with the toys. It's way harder than it looks."

Lily had been watching your dick wake up for this new development, "can we try on you? Maybe it's easier on a real one."

What could you possibly say to that? "Um... sure."

And with that, you were on the couch with the two of them kneeling between your legs, taking turns trying to push your cock down their throat. Both girls were doing their best, challenging their gag reflexes to their limits. It pained you to watch them coughing and spitting, but the feeling of your cock pushing against their throats kept you from stopping them.

"He's too big," Lily theorized, "maybe we should try with a smaller toy?"

Emma disagreed, "it doesn't matter if we can deep throat the toy. I want to do it for John."

If her goal was to make your cock even bigger and harder, it worked.

Feeling them work your cock and feeling it push little by little down their throats was amazing. While Emma was taking a turn, Lily was defeated, "I don't think I can try anymore. It's too much."

You looked down at the mess of tears and spit on Lily's face, and couldn't resist the opportunity to make it worse, "Lily, you've never had cum on your face have you?"
