‘More like a cat purring when she’s happy.’ Her tone was sharp, and I couldn’t stop the cheeky smile. Her dark eyes narrowed at me, but her li...s were fighting the smile. I put my arms around her shoulders, and held her against me. After a moment, she gave a huge sigh. ‘You know, that was one of the things I missed most about you when you were…away. You always gave the best hugs.’ I enfolded her in my arms, and felt her sniff. I looked down, and she was crying. I felt bad, and good, and just. ..you...you're...''Jeez, Steven you just saw them about an hour ago, anyway; and we're brother and sister, right? It's not like you're gonna get turned on or anything!' There was no doubt, she was clearly teasing me. She saw the big bulge in my pants before, she knew very well I'd be turned on. 'Wow...this feels great! So free and natural.' She stood up on the rock and ran her hands through her long jet black hair. Just then it was all becoming clear; I realized that my sister was actually. There was no longer any resistance and she began sucking my full length in long hard sucking backward and forward strokes her eyes transfixed on my mine. She began to jiggle my balls with her hands. I’ve been wanting to do this for a while I said whilst savagely grabbing her big breasts. I began to thrust in her mouth gently building up a rhythm, mouth fucking her while kneading her breasts through her blouse. She deeply sucked my tool making those lips smacking, slurping noises. God, I. As I worked my fingers against the roof of her vagina I looked across to watch Erica. It had only been a couple of minutes since she had cum.Kevin was now kneeling between her legs and stroking her pussy. He then lowered his head and began licking Erica's entire pussy. I watched fascinated as Kevin then slid his tongue between her inner lips and pushed as deep as he could into her wide open vagina.I was totally mesmerized at the sight of Erica allowing another man to eat her. I was a bit.
