The only difference was I could see my hand print on her reddening ass cheek. She solved the dilemma of how to get her weekend bag into my apartment w...th cuffed hands by kicking the bag. It was a slow process but I could see that the excitement and danger of getting caught was turning her on something fierce! Once she was inside, I closed the door again, pulled her down to her knees and removed the ball gag from her mouth."Please!", she squeaked in that adorable little pixie voice of. Her hand slid through my hair, pulling and caressing at it as I ate her.She seemed easy to please, as she groaned loudly. She seemed to on the brink and told me so, urging me on.“Fuck, yes, like that. Eat me out. I’m gonna cum, stick some fingers inside me.”I complied, slipping a finger inside her next to my tongue. This made her body arch as her legs started to shake even more.I decided that I wanted to be an asshole and tease my little sister. I pulled my finger out of her pussy and pulled. I'd have to pull it out in front of him. Like adult men did, right?I reached under my shorts leg to pull my cock through. The shorts would provide some coverage. My eyes focused on the forest. No, my cock was not fitting through there. In fact, this was only making it harder.I pulled down my waistband, only to have it slap back against my cock. Oh no. Here I was drawing attention to myself. I pulled the waistband down again farther to rest under my balls, my cock pointing out naked. I glanced. By now he was leaning forward to penatrate deeper and I noticed i was moaning with each thrust, not knowing i was doing it. Soon he was slamming his hard cock in and out, faster and faster. I thought he was about to cum and thought to myself "i dont want him to cum yet" then blurted it out loud. The guy just laughed, probably hearing the desperation in my voice but i didn't care. "please don't cum yet, I need ass-fucking longer and harder " i begged shamelessly. Once again he just laughed at.
