She stood up, and I don't know what came over me, but I buried my face in her wet pussy and it tasted amazing, her piss and pussy juices all mixed up....I then was needing to get my cock in her, so I spun her around , bent her over the loo and slipped my rock hard cock into her wet pussy. I was pounding away from behind, and I had to slow down, wanted to enjoy her. I pulled my cock out and she sat down on the loo, and sucked my cock.She suddenly stopped and said she needed another pee ! (Too much. "Hold onto it baby - let it grow - you can only cum when I'm inside you" But Daddy - you're torturing me - I can't hold it back"My fingers carefully slid down the outside of one pussy lip, backwards between her overheated butt cheeks, just avoiding her puckered hole, then back up the other side, to glide across her clit. I had no idea how much more of this she could take; the pussy juice was already flowing and she made little moans each time my soaked fingers pulled away.Grace moaned again. She mouthed the words, ‘I love you and I’m horny,’ to him as he got closer. Finally they were close enough to touch and he immediately dropped his carry on bag and wrapped his strong arms around her. He playfully dipped her back as they kissed and his tongue pressed against hers. His hand resting just at the small of her back, before reaching a little lower and giving a playful squeeze. ‘Let’s go home honey, oh yeah, hi,’ she whispered into his ear as they straightened up, her lips brushing his. "Wider," he commanded. She spread her legs wider for him. "Now put your hands behind your head and lace your fingers together. Keep them there, do not move them," he warned. She did as he said and stood there waiting for his next command. Professor Diederich reached between Chelsea's spread thighs, running his hand up and down the insides of her legs with a light, teasing touch. Chelsea moaned softly and closed her eyes as the Professor stroked her trembling thighs. He smiled and ran his hands.
