Turning them inside out he held the crotch to his nose and breathed deeply,he could feel his cock begin to throb as he imagined her s*******n year old...cunt saddled in the crotch of them.Laying down on Lynn's bed he began stroking his now fully hard cock and licking at the crotch.In his mind he felt guilty, after all this was his sister... but he was in the throws of lust and the guilty feelings seemed to melt away.Billy had been so caught up in the moment that he didn't notice Lynn was. He pulled his head back a little at first but then he leaned in for more, parting his lips again as he took my cock head into his mouth licking it with his tongue. Mark moved his head in some more taking more of my cock into his warm wet mouth while I moaned. "Uhh... Mmmm... Ohhh..."Then it occurred to me that maybe he wanted me to be fully hard just like him so we both enjoy this as much as possible. Mark moved his head up and down as he started to suck my cock while I moaned louder feeling. “Come, now”, she said. “Time to get up. I let you sleep tons.”It took a little convincing, but I got up and put on Fiona’s clothes. They were too big for me, but at least it stopped her grimacing whenever she looked at me. Everything hurt, but it was just about bearable. If I was careful about the way I dressed, I could keep the damage hidden.“I guess I can’t stay in bed forever”, I said.“You must be hungry, too. Come on.”She coaxed me to go out of the bedroom into the living room and join her. "Is Linda still in your room?" Alexa inquired in a whisper upon Molly's arrival."Unh-hunh," Molly whispered back. "Go join her."They kissed. Molly and I chuckled quietly at Alexa's grin, big enough to be visible in the dark room."Thanks," Alexa said and quickly pulled on a clingy dress over her nakedness. Once covered she kissed both of us, grabbed her purse and a key to Molly's and my room off the dresser and rushed out the door, pausing only to ease the door shut."You pooped these two out,".
