Yes....

Could you really do this...? This could hardly be more embarrassing; or obscene. Tammy and you were almost in a sort of advanced blow job position and... Oh God the last thing you needed to do right now was think of sexual things.

"Left hand. Yellow." Matilda repeats for emphasis.

You close your eyes and your hand loosens. You don't think either of the McKenzie sisters were breathing at this point. And...

"Eeeeeeeeeeeeeeee!"

The collective squealing makes you fall down, inadvertently losing the game anyway.

You look down. Tammy has covered her mouth, her eyes are bulging. She's shamelessly ogling your privates. She's always struck you as so shy. Either she's secretly more outgoing or even just more sexual than she appears or she's even less socially adept than you thought. Or maybe she was just that curious to see a penis in real life.

"It's so... cute! Not in a bad way!" She catches herself, seeing your expression. "I mean I haven't seen many, and just pictures. Maybe it is... average?" She said unconvincingly. "But I like it." She says, blushing.

"I agree. That you're cute, not with the average thing." Matilda says, bending in closer.

"According to google the average flaccid size is 3 point 6 inches. I don't think you reach that." Shit, she has her phone out!

You cover myself. "What the hell! No phones!"

"Relax, these pictures are just for insurance." Matilda said, matter of fact.

"Matilda that's too far!" Screamed Tammy.

It was a bit hypocritical, given that Tammy had already taken an surreptitious video of your derrière. But it made you feel good that she cared enough about you to have a limit, or at least when it's someone else taking the pictures...

"I just want to make sure nakey boy fulfils his forfeit for losing the game," said Matilda, with a wink.

"What forfeit?" said yourself and Tammy in unison.

"Science." Matilda turned and reached into her school bag.

Tammy and you looked at each other. "What?"

Matilda turned to face you both again with a huge grin on her face and a measuring tape in her hand.

"Science."
