Feeling the warm drops splashing on her skin had been a surprise. Oh, she'd known what was happening, but there was a big difference between reading a...out it in one of her mother's racier novels and actually having it happen to her. And the drops had looked so white."Um, that looked like a good one," she'd murmured. She started rubbing his come into her skin."What are you doing?" he asked when he finally caught his breath."They say a guy's come will make your breasts bigger," she said."And you. Pulling out of her ravaged throat, he ordered her to lie face down on the trestle with her feet on the floor. This time however, he put a thick strap across her back to tie her down. Alyssa gripped the sides of the trestle and Jenny noticed her knuckles were white, so hard was she gripping it. With one hand supporting his thick shaft, Dr Graham used the other to part Alyssa’s pert cheeks. An audible gasp went around the auditorium as the girls realised what was about to occur. Meanwhile, Dr. “Are you sure darling?” asked Allan. “I have never been surer in my like. I want him to fuck me” and without she got on her knees, leaned over the bench and yelled “mount me now”.True to my training the lab mounted her and I was relieved then he found the warm embrace of her pussy without any help. She squealed as he found the target and proceeded to do what came naturally. She moaned and groaned as she was fucked like never before. I suspect no human could be that vigorous as he ploughed her. She's sexually adventurous, sexy, and actually something of a freak. He showed me a photo of her in a bikini and she's quite hot. She's got a perfect tan, amazing figure and huge tits. What's the problem, I asked? "There's no problem, and I love my wife, but there are some things she can't do...like shove a big, throbbing cock down my throat, and I've been craving that lately; a strap-on just isn't the same." I told him I had a hard cock and a waiting asshole and I have never outed anyone for.
