Lia i the middle of the fight pulls you near and as her breasts were in contact with your chest you get a boner. Her reaction to this is "you are one naughty boy (and a grin) never the less the reason i pulled you here is i have a plan just stay behind me and i will try to make sure you stay in one piece but she says he might have to help her a bit in return.
