I'll Always Protect You (слэш)

I saw this anonymous prompt on tumblr and had to try writing it. Props to the anon who came up with this idea, because it's really awesome!!
Anonymous said: If anyone is up for it I have a rescue prompt idea where Peter (he is not in his spiderman suit) is taken as a hostage with a gun to the head along with a few other civilians. Peter is warning the criminals to let everyone go otherwise his fiance,Wade, will kill them all. They mock him and beat him up. Then a furious Deadpool saves Peter by the most badass way possible. Also I would love if someone write how unnervingly skilled Wade is as a mercenary. Please? Anyone?
