My Young Sister In Law 3

So my sister in law stayed all weekend. All Saturday we hardly saw each other as she hung out with my gf and I gave them their room. At night we watched a movie and my gf was so tired and she decided to go to sleep early.
My sister in law was cold as she was in her PJ already. I gave her a little blanket and she took it but also crawled on the couch next to me. For the rest of the movie, a full hour. She cuddled against me. I could feel her body and her braless boobs against me. I had a raging hard on. When we went to bed she gave me a kiss on the cheek. I wanted her so bad.. still do..
