My cock got instantly hard and began to press against her butt crack. Because the windows in her room sucked – literally – her room was always cold in the winter. I could feel the strain building in my balls when my sister said, “How close are you?” I stopped pumping immediately and said, “I’m sorry sis, but please don’t stop me now.”
She answered by pulling away from me, spinning around and taking my cock into her mouth. We lay there for several minutes in each others arms while I left tender kisses on her neck. In all fairness, Jade was a very pretty girl. I was an average 17 year old boy (in other words always horny) and I was tasked with babysitting my 14 year old sister Jade. While it made her bedroom almost livable, it turned my bedroom into a furnace. This time she spread her legs apart and guided my cock an inch or so inside her wet pussy. To prevent her from freezing in the winter, the heat was always turned way up. She replied that she was afraid to sleep downstairs by herself. At this moment I was breathing hard and I wanted my little sister more than I’d ever wanted anything in my life.
