Anal For The First Time

This happened while still in high school around second semester senior year. My girlfriend and I were hanging out one Friday night when she was suppose to go to a friend's house for the night. Walking her there we were surprised to find her friend was not home, she totally forgotten about their plans. Already late and the fact she told her parents she was at her friends house and not wanting to go home.  I told her if she wanted she could stay over at my place. She agreed and so we headed back, arriving with enough time to let my family know the situation. Totally cool with it we went to my room. At this point it was getting kind of late for everyone in the house we were relaxing on my bed while watching TV.  It was getting cold so we slid under the covers snuggled close our hands started to wonder. My hand inside her shorts only to find she wasn't wearing any panties and oh so smooth and wet. Slowly rubbing the outer folds of her vertical lips, covering my fingers with her girl drool. She pulls her self into me moaning softly in my ear grinding her hips into my slippery fingers working between her pussy lips. My finger sliding down to her gushing hole back up flicking her clit.  She begins to moan deeper, grabbing my cock moaning for me to remove my pants. With one hand I struggle to slide them down while she starts working my now dripping wet hard-on as I am still rubbing and fondling her wetness. Now with my pants at my ankles and her moaning in my ear I pull her shorts off as my cock humps her silky smooth thigh until she can free herself from her shorts.  Draping her leg over mine, her pussy now well salivating working her up now really good, my finger slipped lower then expected and brushed her asshole with my wet finger. Not stopping me in any way I continue to wet her little pucker. Her whimpers indicating for me to continue. Suddenly I feel her butthole start to open to the gentle pressure of my finger. She started to jack my cock faster as she pushes back on to my finger  in her ass.  I can feel it tighten yet slippery and warm as I'm now slowly working a second finger inside as my thumb rubbing her clit. Rolling her hips she lets go of my cock. Our tongues dancing in sweet twisted tangled tango as I now have two fingers in her ass, two fingers in her soaking pussy and my thumb circling her clit. Her moans sucking my tongue into her mouth, she grips my shiny hard cock and whispers into my ear, "you, you mmm, ooo can mmm stick this in my ass nnnowww!"  All while my sibling sleeps in the bed five feet away.
