Soon she backed up a bit, "Suck my cock honey" she whispered softly "Get my cock in your fuckin' mouth" she added and one last peck on her lips and I ...slowly sank down to my knees and with her cock still in my hand, I moved in and into my mouth went her cock. "Oh God" I thought to myself feeling that nice hard black cock back in my mouth and savoring the taste as I first sucked her slowly until she grabbed my hair and now began to fuck my mouth hard and fast. I took her cock as deep as I could. Skinner?" he asks and I nod. "Sure, we learned about him last summer during that course I took at the university."

From what she says and from what I've seen of you since yesterday evening I don't believe you ever could either." Thanks. I have to admit that I'm thrilled she does want to sleep with me though. She is a lovely girl and very, very physically attractive." Only physically?" No! She's a sweet girl. She's full of fun and makes me laugh. I've become very, very fond of. One summers day me and John was talking and Jen can to the door in her usual silk shorts and tight vest top,her huge nipples hard as steel and asked if i wanted a coffee while giving John a flirty smile,the poor lad couldn`t take his eyes off her ass as she walked into the kitchen,i laughed and said sorry but she`s a right tart and loves winding lads up.The weekend came and Jen woke me up with an amazing blowjob and i was pleasantly suprised as i looked down to see her wearing her nurses.
