I don't know what the average age of NSers is or how many in tho thread are virgins but the idea of banging on a chairlift is mindboggingly stupid and far fetched.
Never mind the fact that getting your dick up and getting both of your snow pants and whatever else you are wearing down is a pain in the ass, how are you supposed to bang her?
The only feasible way IMO would be for her to ride you. Good luck trying to play ski twister trying to get her skis around yours while facing you. Not to mention, if the chairlift stops suddenly that bitch is falling off backwards and since your dick is inside of her you are going with her.
Once again I reiterate how retarded this is. If a girl on the lift was DTF I would just take her to a smoke shack or my car in the parking lot. Win win.
Carry on.
