You're right. The hand is from a dude. Who is fingering a girl while he is driving. Now dont ask me but that doesnt seems like he is a very safe driving but then again no one asked what i think. And if you say the girls thighs looks manly maybe its because she works out and isnt a fat cunt.

Grats on revealing your virginity

Maybe its a woman and a man :o

Seems you've never actually seen a girl's thighs. And the hand looks normal aswell.
