Now the fucking is over and she grabs her bra from the guy and puts it on herself, loading her heaving tits away, but let’s the panties remain with ...her admirer. She sits up and takes her coat back and puts it on, then I skulk away before she sees me, and I head home, my head is buzzing and confused, but also have to admit it was the sexiest thing that I ever witnessed. I ran back and took the note away from the kitchen counter, and hid upstairs again.About ten minutes later Mom returns home,. I’m going to cum in your pussy, sis. Oh God, your pussy is so hot!”“Yes!” Kirsty gasped. “Cum in your sister. Fill our pussies with your hot semen. My… Oh God. I’m cumming too. Aaahhh!”And she pressed her lips on mine so hard it almost bruised, her aggressive tongue forcing its way right to the back of my throat, leaving no doubt the illicit thrill of this incestuous romp was ramping up her sex drive massively. She was an only child, so to her it can only have been an exciting idea, unburdened. During the drive with his hand casually d****d over my shoulder he soon found his probbing fingers inside my bra, teasing my erect nipple until it just popped-out of my halve-cut bra. I distinctly remember seeing his sister adjust the rear view mirror to watch us then wink to her brother.This occured just as he dipped his head down onto my nipple and as her boyfriend turned to view me in the process of being exposed, she thumped him on the leg and told him to face the front.'I'll take the long. " I reached for my wallet. "No, you have to show me your cock dufus." Oh, right." So I loosed my pants and pulled them down a little to pulldown my briefs and expose my magnificent cock. "Yeah, it's in here, just asecond." As I pulled my briefs down and my crotch came in to full view ofat least four or five people standing around, out came my pussy. "Dude!! You're a chick!!" I pulled up my pants and ran away as fast as I could while holding up andtrying to button my pants. I decided I'd better.
