Try hiding it in the dressing room

You know the game wouldn't make it as easy as letting you run out of the store with it, so you should probably try to be sneakier about it. With another quick glance around just for safety, you casually and calmly pick up the body suit. Even just feeling the material in your hands starts to excite you as you quickly head off to the dressing room.

Once inside you quicky begin undressing. You're still not completely sure how well you'll be able to hide it even with your baggy outfit, but you decide to give it a shot. You drop all of your clothes to the ground, taking a brief moment to look at yourself in the mirror. It's a little strange looking at an extremely realistic naked avatar of yourself, what's even stranger is how similar the body looks to that of your actual one, even down to your below average penis size. Does it somehow know your measurements? Or are you just the stereotypical demographic for this game? You decide not to think about it too much and get back to your mission.

You grab the suit and stretch it out in front of you. You notice your cock shake a bit as you continue to admire it. You quickly begin to unzip and unclasp all the little parts of it before lowering it down to the ground and stepping your foot in. You excitedly begin to pull it up, but pause as you start to notice a problem. The rubber material is sticking against your skin, making it very hard and possibly painful to pull it up all the way. Annoyed that they put in such a mundane inconvenience into the game, you start to backtrack, yanking your foot out, allowing the suit to fall to the ground.

The first solution you think of is lubricant. Surely this store would have some. All you'd need to do is get dressed in your regular clothes, walk back out, grab some and go back in. That should be normal enough to not cause any suspicion.

Happy with your plan, you go to reach for your old clothes to get dressed again... but they don't seem to be where you left them. You frantically start searching every inch of the small dressing room. They couldn't of just disappeared, or could they have? It could possibly be a glitch, or a fully intended challenge that your weren't at all prepared for, either way, you have to figure something out. You could try forcing the body suit on again and just take whatever pain comes with it, or you could stick to the lube plan, only you'd have to walk out completely naked without being noticed. Neither option is ideal, but you have to do something.
