"Hannah, do you know how much cum you just shout out?" asked Cassie.
"Hu...wha?" Hannah still felt light-headed and exhilarated; she had trouble focusing on the bathroom stall because the fog of light, which had overwhelmed her vision, had left remnants which still pulsed. Her fingers and feet trembled; she wanted to do it again. She wanted more.
"I said, do you-" Cassie lowered her voice, with a nervous glance at the place where someone would stand if they were listening outside the stall. "Do you know how much cum you just shot out?"
"Mmm." Hannah sat up a little. She grinned. "Yeah, it's a load, isn't it?"
"Hannah," Cassie said, wanting to have Hannah understand this, "That's way too much cum."
"Oh?" Hannah looked put out.
"Yes!" Cass said. "Haven't you ever slept with a guy?"
"Well, yeah!"
"Then you know! This is way too much cum!" Cass paused a moment to get a grip on herself. "I mean, this is way more jizz than comes out of a boy's cock."
"Yeah?" Hannah looked like she didn't quite believe this.
"So something weird is going on."
"Yeah, I guess so." Hannah's smile had faded, and now she creased her brow. "Man, there's been so much going on..."
She put her head in her hands, and Cass, sensing that their sex-things had aggravated her friend's--whatever her friend had going on--hugged her friend.
