Your roommate makes you wear some lingerie which is really revealing, you made him wear it so you have to as well. As your putting it on you can see him smirking, watching your every movement. You really don’t want to wear this, you can understand now why he is doing this to you. If he made you wear this without permission you’d do the same to him. Once you finish putting it on you feel really embarrassed. You find it quite comfortable though which is quite odd but no matter how comfortable it is you just want your roommate to tell you what to wear next.
