My niece started living with my family about three years ago. She is now 17 and is now turning into a beautiful young woman. She is 5'2' with light brown skin because of her latina heritage. She has a very shapely ass which goes along with her curves. I never noticed her until she started feeling more comfortable around me and wearing more revealing clothes.
One day I was home alone and had to go in her room for something and stumbled across her dirty underware. I picked them up, red lace thong..she just left for school so they were still damp. I could not help myself, I put them up to my nose and inhaled her sweet young scent and became rock hard in a second. I kept them to my face, licking the crotch tasting her juices. I laid on her bed and started to stroke my enlarged cock vigorously and cumming with such a force that cum landed on the pillow next to me. Once I came to my senses I cleaned up and left the room.
That night I was in bed and she knocked on my door and asked to use my computer. She just showered and in she came with short shorts and a loose fitting tank top with no bra on. Her B cup breasts were pointing out showing her nipples through the loose fabric. Holy crap I started getting hard, I was under the covers so it was easy to hide my hard on. She sat down at my desk next to my bed I was no more than two feet from her. She started working on the computer and I kept glancing at her protruding nipples. I started discreetly stroking my cock trying not to let on to what I was doing. Then it happened..She adjusted her leg putting her foot on the chair exposing half of her pussy with a small patch of brown hair around it. I kept on glancing over staring longer each time. The stroke of my cock became faster but still remaining as quiet as possible. She kept adjusting her legs switching her legs off and on exposing more of her sweet looking young snatch. Looking more and more I just realized that I knew what her scent of her pussy is like by sniffing her soiled underware earlier that day.
She remained at the computer for another 20 minutes, by this time I was ready to blow my cock juices, still stroking my cock under the covers, I looked over one more time and saw her pussy and then came as quiet as possible. What a mess..
She finished on the computer and got up, I could not believe my eyes.. She had a wet spot on her crotch as she walked out.. Did she know what I was doing under the covers? Or maybe she found the cum stain on her pillow and came to tease me? I will never know.
