And maybe a colour. The package wasn’t bad. But ‘beautiful’? Oh, I don’t know. I give up. She brushed her teeth and headed to her room. Pa...sing before the mirror over her dresser, she gazed at herself again. She liked what she saw. And she was proud of herself. She’d shut the fact of her nakedness out of her mind today. Mostly. Well, she had to. As it was, the dark grey skirt she wore would have stained if it weren’t for the built-in liner. Only when Professor Malcolm Sartori appeared. Kneeling behind my butt, he penetrates me holding my hips to synchronize our movements.“Mmm... I love fucking this yummy little twat!”His words make me very horny and, watching the scene in the mirror, I lose myself.The image of him fucking me, his cock in and out of me, the stark contrast of my lily-white ass and the brown color of his phallus… I am thrust into a cloud of pleasure.One more moment and I’m gonna cum!However, he has further plans for us.He exits me and leads me to the erotic. She did. After moving up an inch or so, I felt it. The bottom crease created by the meeting of her thigh and the bottom of her right buttcheek. It was incredible. Warm, firm and smooth. Through out this we were both getting pushed around by the pit and by the other concert goers around us so I was trying to be as careful as possible as to not spook her. With each shove and push I slowly moved my hand up further into the bottom of her shorts. I felt the tip of my fingers beginning to get wedged. Those three days me and my sister was like husband and wife. let me explain day by day.First day: it was a fine morning. my sister wake me and gave me a superb tea. i went to have bath and knowingly i left my towel outside. i brushed my teeth and started to have a bath in showers. after taking bath i called my sister to bring me the towel. she brought me the the towel. i dragged her inside and she was wearing nighty and i told her to take bath with me. so i removed her nighty she was wearing.
