My sister has been acting weird lately, and I'm not sure what's going on. She's always been a bit of a tease, but now it's getting out of hand. She's been walking around the house in nothing but her underwear, and whenever I'm alone with her, she's always trying to touch me. The other day, when we were finally alone, she started to touch herself in front of me. Her fingers went right to her pussy, and it was the hottest thing I've ever seen. I couldn't help myself and I started to stroke my cock. She saw what I was doing and she came over and started to jerk me off. But then she took it to the next level and she started to give me a deepthroat blowjob. Her mouth was amazing, and she knew exactly what to do with her tongue. It was the best blowjob of my life.
