"Jesus Christ Tammy what the fuck?"
My older sister Tammy had just jumped on me in my bed waking me up. She was 25 but acted ten most of the time when we were alone. I had turned 20 a few weeks before and was going to college close enough to Tammy's place that she insisted I move in with her. Mom and dad were glad to be saving a little money and they thought that Tammy could use my level headed thinking.
'Wake up Adam. I'm bored."
I looked at the clock beside my bed and groaned. It was only 8:30 and I had been up until 4am studying. Tammy moved her body over mine on the bed and grabbed my wrists. She leaned forward and began to lick my face. I always hated when she did that when we were kids. I began to buck my hips to push her off me. Suddenly Tammy gave a jump and pulled her face away from mine. She got a devilish look on her face. I looked from her face to her chest for a fraction of a second. She was still dressed in her night clothes which consisted of a spaghetti strap t shirt and a pair of boy shorts underwear.
Suddenly Tammy was leaning in and I thought she was going to lick me again. My hips shot up again and Tammy ground down against me. Now I knew what had caught her attention. I had morning wood and when I bucked against her she felt it hit her. She locked her lips to mine and began to kiss me. She kept trying to push her tongue into my mouth and I was slowly losing my resolve.
Tammy was a gorgeous girl. I had always lusted after her from the time I hit puberty. When she went away to college it eased up because I didn't see her every day. Now that we were living together again she was my main masturbatory fantasy.
Tammy was grinding her pussy against my cock as it strained against my boxers. There were three layers of cotton between our bare skin at the moment but I could feel some dampness soaking through my sheet as she moved. Tammy began to moan and I opened my lips and let her tongue invade my mouth.
Tammy's grip on my arms loosened and instead of pushing her off I slid my hands under her shirt, I found her breasts and a second later her nipples. I began to stroke and lightly pinch her nipples while our tongues twined together and her hips ground against my hard on.
The wet spot on my sheets was growing. I began to peel Tammy's t shirt up and she broke the kiss long enough to shed it and then she dove in again. This time I was ready for her and thrust my tongue inside her mouth.
