Well there really is nothing you can do about getting an erection. I mean if ANY girl puts her hand there and starts stroking, no matter how hard you try ya dick will always grow. I dare anyone to say anything different.
...and this is where I disagree with you.
I get the part about you gettin aroused, but you were fully aware she was your cousin and you let her hand on it for a minute? Even that's a little too long, man.
Kinda reminds me of the time I was in the Philippines for the first time in like 10 years. I met these 2 hot chicks and was really clicking wit 'em. We got along really well and it looked like we'd be very close friends. So like a week later, we were talkin and my mom comes along. I introduce them to her. I'm paraphrasing here:
Me: Hey, this is ____ and ____
Mom: Oh hey, I know you two...
Girls: Oh really?
Mom: Yeah, aren't you Ronnie and Dave's daughters?
Girls: Yeah, we are.
........................
Me: UNCLE Ronnie and Dave?!?
[Me and the girls look at each other]
