Don't do it, bro.
Seen here being modeled by the saddest lovedoll I've spied all week (and that's saying a lot because I made the mistake of opening my roommate's closet), this is the 'R2-DD2' bra created by Instructables user seamster. It has light up effects and even beep-boops if you touch the ends of the nipples. Plus makes me inconsolably depressed.
Hit the jump for a video of the boobie droid in action.
Thanks to my buddy Terry, who doesn't care if the bra offers zero support, he's determined to mash his man-tits in there and post the pics to Facebook.
