You cannt believe that something could actually grow breasts, but it was worth a try. You had always been jelous of your girlfriends breasts, but you had never said anything. You quickly stripped so you could see everything. You set the gun to DD and placed it on your left butt check. You knew you would have to give yourself breasts in the normal place, but you wanted to try it somewhere without a nipple, to see if it would create them. You pulled the trigger all the way down to speed up the growth. You could feel your hand being pushed out. You could also feel a weight on the left side of your butt. You moved the gun to the right and pulled again. You felt an equal weight grow over yor right butt check. You set the gun on your bed and crane you neck around. You deacided that you needed a better view. You head into the bathroom to look in the full length mirror. As you walk you feel the alien sensation of something swaying. The movement feels strangly erotic and you notice as your cock starts to stiffen. When you get in the bathroom you see that you have indeed grow a pair of breasts over your butt. They are at least the size of your girlfriends breasts. You could also see that you have heafty sized nipples. Remembering how your girlfriend acts when yountouch her breasts, you know that you will have to be careful when you sit down.
