I took a turn as designated driver, drinking diet cola, as my wife Linda and her co-worker Helen shared two bottles of wine that night. They were accountants at an auditing firm. Helen had been ‘Our’ girlfriend a couple of months. She sort of liked me and was desperately in lust with my wife. As a greeting she held my hand and gave me a peck on each cheek, then French kissed my wife and groped her bottom. Watching was quite erotic, but I jealously wished for the same treatment. After a delicious dinner at a nice restaurant and a comedy show at the theatre, we moved our fun to a hotel room.

They got me going with a brief but hot team blowjob, and Helen allowed me to screw her from behind with a condom while she made out with my wife. I think she mostly tolerated me as a courtesy, so I wouldn’t object when they ate girl pie for hours.

After they finished each other three or four times, I moved to enter Helen doggystyle, from behind again. She said, “I’m exhausted. Next week.” My wife took pity on me. “I’m tired, but go ahead.” She was obviously satiated, but laid on her back and spread her knees.

I didn’t want a sympathy fuck. “That’s okay. Next time.”

We dropped Helen off at her house, then I drove home a bit disappointed. Still, how many men ever get a threesome? We had mostly happy play dates two or three times a month. I was quite a lucky guy, but still wanted more.

Linda and I got home around one am. She asked, “Would you take the trash out? I’ll go check on the boys.”

“Sure, babe.” I lugged a heavy trash bag out the back door. Our pretty brunette babysitter Karlie leaned with her back against the wall in the back yard, sucking on a cigarette! It was easy to see the shapes of her small breasts in her thin white shirt, and even a hint of nipple!

She was startled and afraid to see me, exhaling a cloud as she rapidly apologized, “Sorry! Please don’t tell! Please?”

“Uh...” I thought a bit as I dropped the trash bag in the can. Her mother was our girlfriend, and she and my wife both smoked. The legal age to buy cigarettes was twenty-one and she was only eighteen, but I didn’t think they would care much.

Karlie pleaded, “Please? I’ll show you my boobs, if you keep it a secret?”

“Um...”

Before I could reply, the cute and slender high school senior lifted the front of her 56004-1-04-sitter-boobs.jpg shirt. Her sexy little breasts were round, firm, and didn’t droop at all. Being a fluid dynamics engineer, my mind rapidly estimated their radius and volume. ‘140 cubic centimeters, 32 - A, nice!’ They were a small but arousing change of pace, from playing with my wife’s big double D’s and our girlfriend Helen’s C cups. I mumbled, “Um ... very nice!” “Don’t tell, and I’ll let you touch ‘em. Just please keep it a secret?”

“Ah ... okay!”

She held her shirt up with one hand and smoked a few more puffs with the other, while I fondled her sexy little chest. Her boobs were quite firm, and the pea-sized nipples on them were swollen and quite rigid. Despite already climaxing that night, I felt myself stiffen.
