Yes

For the first time in this turn of events, Tammy is smiling as well.

"Oh my God, that's amazing! Will you let us... let us measure.... it?" Tammy is visibly excited now. "Please! I swear I'll make her delete the pictures, and.. and I'll delete my video too if that's what you want. This is so much fun and we'll keep whatever we find between us, right?" Tammy looked up at Matilda.

"Sure. We're not mean girls." She grins. "We're just really into science."

Sigh... You look between Matilda's mischievous face and Tammy with her big cute smile and pleading eyes...

"Please... please delete everything okay?"

"Awesome! Tammy, you get those hands away. I'll be right back." And with that, Matilda dashed into the kitchen.

You turned to look at Tammy. She was sitting cross legged and finally looked a bit embarrassed about all this.

"Seriously thanks for playing along with all this. I never meant for any of it. But I'm pretty glad that it happened. As long as we're still cool..." She stood up and started leading you towards the couch. "Sit."

You obeyed. "Yeah... just delete everything... and don't tell anyone. And we're still cool."

She sat next to you and smiled. "That's great to hear. I'm relieved. Now... I don't think you have anything to hide from me any more... do you?"

Taking the hint, you let her gradually move your arm away. You were once again exposed.

Matilda returned with... your underwear?

"Hey you two lovebirds. Tammy do you want to do the honours and I'll write down the measurement in my notebook. I'd love to take a picture of the measurement but..."

"Yeah that's a no!" You said.

Tammy kneeled down in front of you with the tape measure. Wait, was she about to... touch you?

She hesitated. "I guess one of us will have to hold it and one of us will hold the tape measure."

You held your flaccid member out. As amazing as it sounds to have a girl touch you there for the first time, this isn't exactly how you’d want it to happen.

Hands shaking a little, Tammy held out the tape. Her fingers brushed against your pubes.

"2 and a half inches."

Your heart sank. You knew you weren’t big but it didn't feel good to hear it. Tammy was smiling at you though. Even Matilda looked fairly neutral as she jotted the result down. They weren't mean about it.

Thinking your ordeal was over, you were about to get up when Matilda said, "okay, next measurement."

"Next measurement?" You asked, puzzled. "You want to weight my balls next?"

"That would be pretty funny, but I don't have a scale sensitive enough," Matilda giggled. There's the mean girl back.

"No I have to capture a range." She said, as she handed you your underwear.

Tammy looked as confused as you were.

"Sis, I don't want him clothed yet."

"Oh don't worry, he'll be taking them off again soon." Matilda replied, with a sly look on her face.

No sooner had you stood up and happily pulled your underwear back on, Matilda pulled out the waistband and dumped a glass of ice down the front.

"Oh my God, that's freezing! What the hell are you doing?"

"Just stand there for about five minutes and don't move too much," Matilda replied.

"Sis, what?"

"I said I wanted to get the range. I want to measure just how small our little friend can get."

Tammy's eyes widened. "Ooooh! Oh that's interesting. Do you think it can get much smaller?"

"I mean it's possible he was even a bit aroused being ogled at by the girl he likes. Maybe he was half erect."

"HEY!" Tammy and you snapped in unison.

Matilda snickered. "Actually maybe you should leave in case he causes another protrusion in there, other than the ice. Go get a towel from the bathroom."

Tammy looked like she was about to challenge her but then noted the puddle at your feet, and turned to leave. "No funny business."

"Who, moi?" Matilda smiled in a such mock angelic face that even you had to laugh.

With Tammy gone Matilda turned to you with a serious look on her face.
