A young man on a road trip

I don't know why the hell I agreed to go on this road trip as even if it contained everyone that was supposed to go, I'd still hate most of the people in the road trip. I had just turned 18 a couple months ago and my parents wanting me to get out more had convinced, by paying for most of the hotel stays, my brother to drag me along and had pressured me to join them and their friends, but in the end all of the friends dropped out on incredibly flimsy reasons.

It was almost like this whole thing was a half baked attempt by my gym bro brother and his girlfriend, my former baby sitter and stereotypical former high school mean girl, attempt to milk our parents' for a fully funded bang trip, but my presence ruined that and I've been nothing but the butt of their jokes to a degree never seen before.

The two of them very much match the sterotypes, my brother tall, tanned, muscled and broad shoulders, while his girlfriend is conventionally attractive, average chested, and blonde with a pretty albeit with a resting bitch-face.

For the first time in the trip they surprised me in being awake before me, though considering the shower is currently running and Melissa looks like she just got out of a shower I don't doubt they were in the shower together. The only clothing I can see on Melissa is one of my brothers oversized gray pullovers as she constantly flips through the free channels of our room's flat screen TV.

"Will you just pick something." I complain as I'm sure she's gone through a loop for the third time, or at least there's 3 different channels playing the empire strikes back at the exact same spot.

"Just keep playing your kiddie games on your phone and shut up." Melissa bites back seemingly increasing the channel surfing. As I continue to scroll through reddit finding nothing of interest.

"I'm not playing anything."

"Oh GOD! Are you like over there tugging it to some porn?" She whines surprising me, the farthest she's ever gone is accuse me of stalking women on instagram.

"What? What is wrong with you I-" I start before something hits me in the side of the face.

"Here, dweeb, why don't you jerk your little peen to that." Melissa laughs as I manage to pull the rather sticky panties from the side of my face, for a moment I'm horrified as I bring it closer to my face and find myself sniffing them as my average sized cock hardens.
