For a number of years my birthday presents had gotten lame, ties, cheap tools, and tee shirts. The wife and I recently had started swinging, and for her birthday I had taken her to a nudist camp where she made the most of it with some of the guys there. But as my birthday approached, there had been no discussion of reciprocating or even anything special. We had dinner and cake with my folks and our kids, and I found that the kids were staying with grandma and grandpa that night and we had the house to ourselves. As we rolled in the driveway Karen stuck her tongue in my ear and grabbed my crotch, "I have a special present for you tonight" she whispered. She sent me off to the shower, "but don't waste time putting anything on."
As I dried myself off she came in with a blind fold, and put it on me, but she was still fully clothed, "shhh don't worry"! Was her answer to my question why, she blind folded me and lead me by my penis into the family room seating me in a straight backed kitchen chair, she had placed there. The cold vinyl was sticking to my ass and balls as she tied my hands down lightly to the legs of the chair, I could hear another voice maybe two giggling as she did this. She removed my blindfold, on the couch sat three of her friends, Pam my best friend's wife, Cory a young gal Karen works with, and Scarlet our new neighbor across the alley. "Well girls, he's yours, I'm going to a movie." She stopped at the stairs and looked at me "I love you... enjoy" she mouthed then she was up the stairs and out the door.
"We decided to give you a show... a birthday suit show!" Pam was excited as she spoke; she walked across the room and turned on the stereo. With Billy Joel playing in the background she came to me and kissed me hard on the lips as her hand traced down my chest, to my stomach, her fingers lightly played across my growing member. I first met her the day before she married Mike, she was eighteen and hot, now ten years later, she works as an aerobics instructor and is still hot. Her shoulder length brown hair played across her shoulders as she danced. She wore a black halter-top, no bra, and tight blue jeans, her thin body accented her medium size bust, making her tits look larger than they are. She sat on my lap facing me, dry humping me, her jeans rubbing roughly across my crotch, she peeled her shirt off and smothered my face with her breasts.
She slid off my lap, rubbing her nipples across my chest and on to my lap, a gentle kiss on my pink head and she was dancing again, her tight jeans slipping down her legs. I glanced at the couch the other two were watching closely obviously enjoying the show. Pam wore no panties and as her jeans slipped over her fine tight ass, she turned winked at me, and showed me the moon, her pants were kicked into the corner. Backing towards me her moist pussy was inches from my face; she stepped back burying my nose into her ass, my tongue found her clit, and was licking up her sweet juices. Sliding off my face she settled on my lap, pushing my rock hard cock down, her wet cunt lips sliding over the top of it. My eyes were closed in ecstasy, AC/DC was playing as she moved from me, my eyes opened to see Cory dancing in front of me.
