He was taking off his shirt as he walked. He stopped, leaned toward Mrs. Smith, and gave her a quick kiss. She smiled radiantly and slapped him on the...ass as he walked away.Sarah glanced back down toward Bob and Kim. They now were fully engaged in each other and oblivious to everything else. Bob's hand caressed Kim's firm breast. When he moved his hand away, Kim's nipple was clearly outlined in the soft fabric of her clingy shirt and was easily visible even from one level above."I don't know. Unbuttoning her pants they fell down, “Oh my God” she said as my finger slipped over the front of her knickers, licking her nips and running my finger over her pants she had her hand in my hair. I slipped my finger inside her panty line and straight onto her wet gash, as I rubbed her clit I ran my tongue down from her nipple onto the waistband of her knickers, she moaned saying “Oh God!!”Putting my fingers into the waistband I pulled her knickers down, and off her ankles, parting her thighs I. She nodded on my cock, sucking fast and hard now, her hand slowly began to massage my balls, as if she instinctively knew where her hands should go. I felt the pressure in my dick begin to increase and I knew it would not be long before I came, so I quickly stopped her and stood up, having her face look directly up at mine. I quickly grabbed my dick and began vigorously jerking it off over her."I'm gonna cum all over your face Erin" I said, and she continued to look up and me."I want you to be. "It's practice." Practice?" I told you I want to be a doctor, right? Well, what I want to be is a pediatrician." Judging from my siblings here, you've certainly got the bedside manner thing down already." It was easy with them. They're good kids." I gotta get 'em ready for bed. Wanna help?" Actually, if you don't mind, I'm gonna crack these books. I did tell you if I came over with you, you'd have to put up with me studying for a bit." Right. OK, come on guys, let's get those PJ's on!"Sophia.
