Fooling around in Gina's room

We lay down on Gina's bed and started watching some show on TV. It wasn't the most interesting show so I started to tickle Gina, she is quite sensitive and sometimes you could make her giggle just by touching her. As I started tickling, she immediately began laughing and squirming, trying to get away from me. Then she fought back and tickled me, but that didn't faze me at all. She basically had no chance.
But she suddenly surprised me by almost throwing me off the bed and I found myself lying on my back. Gina tried to grab me, but I moved and she only managed to get my pants and since she tried to hold on to me, she almost pulled my pants off. We both came to a halt.

"You know", she began. "I could very easily pull your pants off and you would be naked down under." She smiled.
"Yeah, I guess you could do that", I replied, being pretty sure she wouldn't do that.

Gina looked at my crotch, bit her lip and pulled. Not only did she pull my pants down, she also managed to pull my boxers down with them. My cock was suddenly standing at full alert, jumping up to greet the one, who saved him from the imprisonment that I call clothes.

"Holy shit." Gina looked at my cock. "It's actually fairly big."
"Uhm, thanks?" I didn't really know what to say. "So, blowjob?", I said jokingly.
"Nah, I don't like to give blowjobs, sorry. You'd have to ask my mom for that." I gave her a disappointed look and she laughed.
"Maybe I should go to your mom then."
"Oh, I can just call her over, if you want."
We both laughed. With every other person, this would have been awkward as all hell, but with Gina it was simply funny, that's what I liked about her.
