I met Jo's friend and had a 4sum. Jo's new idea was a gang bang at a club so the following weekend we went to a club. 

We changed into towels, or rather I did. Jo pulled mine off and draped it over my shoulder. 

“You have a good cock, show it off.”

We walked into the club. There were two couples and five guys.

“Let's see what they have.” Jo suggested. 

We took a walk around the club followed by one of the guys.

We selected a large room with a large bed.

“Fancy fucking me?” She asked the guy as she lay on the bed.

“Can I?”

It was a shock that she never consulted me, but I said “Fuck her.”

He started opening a condom.

“You don't fuck me with one of them.”

He looked at me, took his towel off and climbed on her using his hand to enter. He did not take long and rushed off.

Jo sat up. “Come here. I need a real man." 

I lay beside her and kissed her.

“Fuck my ass I need it lubed.” she told me as she adopted all fours.

I started banging her.

“Fuck that's good, keep going.” 

I was banging her hard, partly because I enjoyed it and partly because she had just fucked a stranger. Jo was soon yelling and cummimg, I filled her. I pulled out.

“Did you like taking me back?” 

“It was OK.”

“Checky.” Jo noticed a man at the door. “Stick around you can fuck me later.”

We sat around in the main room with orange juice, sitting on our towels. The place was filling up. Most were wrapped in towels, a few of the women in something more sexy.

“Bang time?” Jo asked.

“Bang time.” I answered. 

“Get me some cocks then”

I walked over to a group of single guys. “Anyone who fancies a gangbang follow us.”

We led them to the room we had used.

With a room full of guys Jo kissed me and handled my hard cock. I knew she was going to get their cocks in her, but she had a surprise for me. She spread our towels out.

“On your back she told me.”

Jo settled on my cock, then leaned down to kiss me.

“Tell them to fuck me now.” She whispered. 

“DP?”

“I was not leaving you out.” She kissed me.

“Who's first?” I asked.

No one answered, then a towel was thrown down on the bed and I saw a guy over her shoulder. 

“Me”

I felt him take her ass. After him another cock in her cunt. Then another. Cum was running over my balls and down my crack.

I glanced at the door to see it crammed, there was a woman there.

Another cock slipped into her cunt beside mine. All the time comments were being made.

Then there was a woman beside us getting fucked.

After the fourteenth cock I was getting limp and Jo sat up and started to move. She looked down at the woman without changing the sweeping motion of her hips. “Hi, nice cock is he.”

“Not bad.” She replied. 

“Can I borrow him later?”

“If I can have yours.”

“Anytime.” Jo gave me away without even asking me.

Jo continued to move and came again just as I did for the third time. How many times Jo came I have no idea.

The towel was soaking and Jo was as high as a kite. She sat there with her head in the clouds.

“I don't think I can move.” Jo declared. 

“Sure you can.”

“No, my legs are asleep.”

“I'll help.” I pushed her off me.

“O'god” Jo exclaimed as I rubbed her legs.

“You OK hun.” The woman asked.

“I'm so OK.” Jo sighed.

When we got back to the main room the women gave Jo some evil looks, I don't think they approved. The men looked with lust.

The woman's name was Tammy, who had kept hold of her man who called himself Jeff.

The four of us did get to a lockable playroom and they swapped us.

I did get Tammy's number.
