When my son turned 18 I wanted to give him a special treat.  I wanted to give him a sexy blow job that I had concoted over the many months leading up to his special day, only to learn that he and his friend Karin were going out to celebrate instead.  Imagine my disappointment.  Here I was dressed all sexy for him, pineapple rings in the refrigerator, whipped cream there too, and he is going out. So I told him he couldn't leave until I'd given him his present and he'd have to tell her he'd be late.  I told him to go into my bedroom and get undressed which he dutifully did.  I then brought in a towel to lay beneath him. 

He is always hard but I still like to play with his balls and lick his cock.  So there he was, naked, laying on the towel when I went to work.  I reached over and got a cold pineapple ring and slid it over his dick, the juices running down his balls, and down his ass, onto the towel.  I slid another ring down his hard shaft running my tongue up to lick the juices, both of us moaning.  He liked this and pushed his mom's head down onto his cock.  After four of the pineapple rings I decided to stop and instead reached for the whipped cream, shook it, and sprayed his phallus.  Then I took him into my mouth and enjoyed the best pineapple split I'd ever had.  He yelled, "Oh Mom, I'm gonna cum!" and exploded in my mouth.  I swallowed every drop down my throat.  He said, "Oh fuck."  I said with a smile, "What did you say?".  He said, "I love you, Mom."  I replied, "Happy Birthday, Zachary!  I love you too."  A short time later, I climbed onto his dick and fucked him, pineapple and whipped cream up my pussy.  I imagine he was well satisfied when he finally left our home later that night.  I had his cream inside of me, along with a little pineapple and whipped topping for good measure.
