This happened about 10 years ago.
I was a very shy single guy with a big crush on my beautiful housemate. She was very popular and outgoing, and even though we got on really well, I was way too shy to take the plunge and make a move. Instead I just acted like a sad creeper and spent hours in my room getting addicted to porn and fantasizing about her.
I felt really ashamed about this, but the shame actually became part of my fantasies. The more perverted I felt, the more intense the pleasure as I played myself.
I'd found her used panties in the bathroom a couple of times when she'd accidentally left them after a shower, and these treasures provided with me with hours of pleasure as I smelled and licked them as I stroked myself. Sadly for me, this only happened a couple of times, and so I spent a lot of time thinking about sneaking into her room to find some more.
One day when I was feeling particularly horny, I saw my chance and was brave enough to act on it. My housemate was meeting up with some girlfriends to go shopping, and dashed out of the house as I was eating breakfast. I was alone in the house! I quickly finished eating and went into action.
I went to my room, stripped off and grabbed a towel. Then went for a long shower and shaved my pubes so I felt as sensitive and perverted as possible. I went back to my room, hung up my towel and walked through the house naked to her room, my cock rock hard and already dripping precum.
I opened her drawers and looked at her underwear as I stroked myself gently, savouring the moment and breathing in the smell of her. Then I found her dirty clothes, and started going through them in a frenzy, smelling them, rubbing them over myself, wrapping them around my cock.
Suddenly, a key turned in the lock at the front door, and I panicked. I hurriedly started shoving her clothes back into the basket, completely naked as I heard footsteps coming quickly down the hall. Out of instinct, I dashed into her closet (she had a whole wall full of clothes, practically) and shut the door behind me almost exactly as she walked into her room.
I crouched in the darkness, still clutching a pair of her panties, and peered through the cracks with my heart racing. She was talking on the phone, and turned and started opening drawers a few feet from me. My stomach went into a knot as I thought she was going to open my closet too - and would see me crouching naked, with a hard on and a pair of her panties in my hand. This thought absolutely terrified me, but at the same time excited me even more.
She suddenly pulled out a bikini, and stood up and started to strip off. I couldn't believe my eyes. Naked she was even more beautiful than I had imagined. She slipped the bikini on, wriggle back into her shorts and top and rushed out the door again.
I fell out of the closet and carefully put everything I had touched back where it belonged. All except for one used thong which I took back to my room and edged with for the rest of the morning.
