“Tell me more, I am intrigued.” Minutes later I am more than intrigued and ask Ros to make it happen after she told me, “Let’s stretch the boundaries, a foursome, Carla for your man and me for you.”

I had recently watched Ros blowing my man while I had two men pleasuring me, though she had never even laid a finger on me, so the thought of her providing sexual pleasure for me has great appeal. And perhaps me pleasuring her in return. My man and I have never seen her naked, something I am looking forward to.

I am Julie, I am blessed with a high sex drive. My man Charles and I are in our early forties, we are both bisexual and we enjoy an open relationship with an extra man or woman on a regular basis.

On a lazy, slow Tuesday afternoon, just the type of day for unhurried erotic sexual pleasure, we are back in the familiar surrounds of Ros’s lavish condo. My man Charles is expecting some type of ‘special sexual attention’, though I have not provided him with any details.

Just a few minutes after we were expecting her, Ros arrives with Carla. A tall, stunning, dark skinned brunette dressed in a knee length white designer coat, heels and white stockings. “Happy birthday Charles, your lady and Ros arranged me for you today. Am I what you expected?,” she asks in deep voice. “Help me off with my coat would you please Julie?”

Carla is almost naked without her coat, just hold up stockings and a high wasted white g-string. She has a beautiful feminine body, slim waste, good size firm tits, 36C I guess, with already erect nipples and a magnificent, large, firm and glorious ass. Her ass cheeks look fabulous divided, separated and highlighted by her g-string. My man Charles already has an obvious erection under his clothing as he takes in Carla’s body.

“Ros told me she is going to pleasure your lady while I pleasure you Charles. Would you like to watch Ros pleasuring your lady? I have watched her and she is very talented. Would you like to watch me undress Ros for you? She does like me undressing her, we go back a way,” Carla smiles as she stands behind her and kisses her neck as she slides the zipper at the back of the dress down and helps Ros shrug out it as it drops to the floor.

Ros is naked under her short silk, brand name dress. A very attractive, tight, size-ten body, small tits with surprisingly large nipples (I can’t wait to lick and suck them) with just a sliver of hair each side of her cunt lips. “I am bisexual and I want to pleasure and be pleasured by three people,” Ros whispers.

I told you I could organize something special for you and your man, really special, let’s stretch the boundaries Julie,” Ros smiles as we watch Charles avidly licking Carla’s nipples. “Now stand with your hands on the wall and above your head Carla, Ros tells her as she licks and kisses her ass cheeks.

“This is something very special I organized for you and your man Julie,” Ros smiles as she slides Carla’s g-string down to her ankles. “Now turn around with your hands on your hips Carla.

“Is that special? Does that stretch your boundaries?,” Ros asks with a huge smile as Charles and I both ogle Carla’s flaccid cock as he flaunts it for us. No pubic hair apart from just a tuft of hair above his cock.
