This happened last year, and I still think about it.
The summer before last, H my cousin, had to live with my dad and I because she couldn't support herself yet. She had a room at the end of the hallway, a couple of doors down from mine.
H has blonde hair and blue eyes, cute, but a little chubby. She was 25 at the time.
One night, as I was sleeping, I woke up at around 2:00am to a noise. I walked over to her room and listened closely. She then let out a very loud moan, which hardened me immediately. Oh I had to jack off. She had the TV on really low to muffle the noise, but it didn't work. I had some oil with me, and I was masturbating on the floor outside her room, and I heard her moan again. I know exactly what she was doing in there. I couldn't help myself and I felt myself cumming. It was nice and hot. Afterwards, I went to bed.
A few days after that, I heard her in the bathtub breathing very heavily. I wonder what she was doing?
She moved away from us about a year ago, but we go to visit often. I caught her looking at my crotch once and I always like to make sure she can see my boner if we are in the car together. I'm sure she has.
Those are my enjoyable memories, I hope they did something for you. Now go and please yourself, you deserve it.
