Want To Get With My Roommate

So I live in a town home with 2 people. I've been living with them for about 9 months. Since moving in, we've pretty much kept to ourselves but every once in a while we talk. There is a guy in the room across from me and the female roommate lives downstairs in the basement. She's the oldest in the house also. She's 40. I'm 30. The guy is like 28. She's kinda that lonely, single, cat lady that isn't very attractive to be honest. Literally the first few months I didn't even find her attractive at all. Well she went on a trip a few months ago and asked me to feed her cat while she was away. He cats bowls are in her room. I was like cool. Got it. I went downstairs in her room, fed her cat. As I was walking out...saw her hamper....panties exposed on top. Something took hold of me and next thing I know, I'm standing there, dick out, panties up to my nose. They smelled so freaking good. I cum immediately. I'm like oh shit. Put them back. My other roommate was gone by the way. Next day, go back down. Feed her cat again. Panties up to my nose. Cum immediately. Next day, I got kinda curious and I looked in her night stand. I know I shouldn't have but I was curious. Inside her top drawer....was the biggest fucking dildo I've ever seen. A huge veiny purple rubber dildo. I was like no way she freaking puts thing inside her. It turned me on even more. Now whenever I see her, I just...get turned on.
