I got back in and they must have been watching me because they were going at it again in no time. There was a little more room now and they took advan...age of it. We got to the second house and I realized there were 2 boxes for this house. I said let me try it alone. I walked to the house with the first box and as I was putting it down a young man came to the porch saying what is this for. I told him to take it in and I had another one in the van. I walked back, thinking he was carrying the. As she sucked him, he found her round ass hole and began to finger around it. She then sucked him hard and he inserted his finger into her ass. As her head bobbed up and down on his cock, he finger fucked her ass and soon he added one more finger in her hole to really fuck her. With his fingers invading her ass she really put a great suction on his cock and soon he came in her mouth filling her with his warm cum. She sucked him getting all the cum which she swallowed and then licked him clean.. She initially hated my treating like a little slut but now she was enjoying my tongue going in and out of her pussy like a whore. She was moving her crotch like a lusty lady and she spread her legs wide to give me more room for deeper penetration.I pointed my tongue and shoved in her asshole and licked up till her pussy. She was going crazy.“Ummmm uncle, don’t stop.. Don’t stop”.“I so much need this”.“I missed you so much between my legs”.“Ahhhhhhhh ahhhhhhhhhh”.And she cum very hard and I. "Stop fucking with my mind David," she breathed, "And fuck me instead."I won't pretend that I hadn't wanted to make love to her, she was a gorgeous woman, she always had been and she was the reason that, at the ripe old age of twenty-seven, I'd never married.I sank into the warm wetness between her legs and for at least ten seconds we clung together, both climaxing, me shooting into her and my sister writhing as she accepted my seed."Jesus!" I'll second that," she giggled after we'd calmed.
