My heart raced and my fingers felt clammy. But I couldn’t back out now. I unhooked my bra, swaying my upper body right above her grinning face, taki...g my time and making sure to keep the bra safely in place. I kept swaying, waiting until I saw a flicker of impatient annoyance in her eyes, then leaned down a little more and whispered into her ear, “Happy birthday, honey. Do you want to open your present?” The explosion of greedy joy in her face sent a thrill through me, and when she reached out. We both closed our eyes and leaned our faces in. And we kissed each-other. A brother kissing her sister. It must have been her first time kissing someone because she started taking out her tongue. I also took out my tongue and when our licks locked I would push my tongue in her mouth. It was so hot and felt so amazing.She eventually stopped kissing me. Our lips were all wet with each others saliva. As she was pulling her lips away, saliva was still connected between us.She opened her eyes and. Surely she would be able to stop before anything happened. Surely the fact that he didnt actually come inside her would make it alright. She could have a little fun doing a doggy and have him come all over her butt. She teased him some more. Do you think I make a good naughty schoolgirl? Slurp! Lick! Its the panties, isnt it? Ive never been fucked by another man before, she declared relishing the use of such dirty language, and bobbing her pretty head up and down his raging penis. Craig just. “But I’ll leave the door unlocked if you want to join me. Wink, wink, nudge, nudge.”“Get the fuck out, Daniel” I deadpanned and he laughed.After the door shut, I pulled my stretched and ruined panties off along with my tank top and tossed them onto the floor with my comforter that we’d kicked off the bed last night. My room reeked of sex, but I really didn’t feel like changing the sheets and I wanted to wait for Daniel to finish his shower before I took mine. It really wouldn’t do for us to.
