Experiment

----

After my night with Marcus, Rosy and I stayed in touch. I found it exciting that instead of Marcus communicating with me directly, Rosy was always the one to tell me about Marcus.

She told me that Marcus had given her the dish on our fucking session and told her how much he had enjoyed being fucked till he came without touching his useless cock. She sent me daily snaps of Marcus shaving his legs, or taking a shower, or lazing around the house practically naked - "He is always thinking about you and upset with me because I forbid him from cumming or ruining his pussy with toys." Rosy sent me a snap with Marcus opening his ass cheeks with the tagline "We have a opening that I think you should fill."

It seemed to me that Marcus relished being dominated and pimped out by his wife and she loved showing how much control she had over her otherwise sexually useless submissive bottom gay husband. It was obvious the two loved each other and accepted each other in a way that is rare for any couple.

Rosy asked if she could watch next time Marcus and I had a play date. I was intrigued. I really enjoyed fucking Marcus. He was submissive, prepared, and full of cum that I could fuck out of him. And the idea started to grow in my mind that having Rosy watch us would be one heck of an experiment.

So, I agreed to Rosy's suggestion.

She was super-excited and we decided to meet up at their apartment that weekend on Saturday.

Rosy's updates on Marcus became more frequent, graphic and revealing as the week progressed. "He really wants to suck you off so I got him a dildo just for oral practice." "I caught him jerking off today thinking about you and had to spank him for this. Good thing I caught him before he could cum." "Marcus got into my lingerie drawer and is feeling extra kinky."

By the time Saturday rolled around I was really in the mood.

I reached Marcus and Rosy's place at 6 PM sharp.

Rosy opened the door. She looked great in a revealing black cocktail dress.

As I stepped inside she kissed me on the lips. I was a bit surprised but it was a nice warm friendly kiss.

"Marcus is in the bedroom. He's too desperate to socialise first. So please do the honours."

Rosy led me to the bedroom. Marcus was sitting on a couch opposite the bed. He wore a sleeveless black T with silk black fitted boxers and a silver anklet. Rosy remembered all my preferences and had prepared Marcus to perfection.

He excitedly rose to great me and we hugged and kissed as Rosy dimmed the lights and unobtrusively sat down on the corner couch.

Marcus and I were both so hot for each other and we undressed - only his anklet remained on him.

I eased him towards the bed and and sat him down my cock dangling near his face. He greedily took it into his mouth, holding my shaft and enveloping the tip. I could tell he had been practicing. I told him he was doing a great job and he was such a good cocksucker. I was so lucky to have him.

As much as I enjoyed getting oral from Marcus, it was his sweet boy pussy that I craved. And he needed me inside him too.

I put on a condom and turned him around on his stomach arching his pelvis up a bit by putting a pillow underneath. I then mounted Marcus and entered his deliciously well-lubricated boy pussy and filled him with my thick 6 inches long banana cock. He moaned and squealed and groaned in pleasure as my cock massaged his insides and shocked his suppressed prostate with its strength and shape.

I fucked Marcus with abandon and his moans and cries waxed and waned as I brought him to climax multiple times. His whole body had tremors as I ravaged his hole and let him feel the real power and strength of another man - something he so had badly needed to feel not just now but for his whole adult life.

I completely forgot that Rosy was sitting in the corner of the same room enjoying watching me fuck the cum out of her husband. Maybe she was taking pictures. Maybe she was masturbating. I didn't know. I was completely focused on Marcus.

I began feeling my orgasm building as Marcus's whimpering became more subdued. He had come multiple times and made a mess of the pillow underneath him. As I pounded him for the final stretch, my thrusts became harder and deeper. The smoothness and warmth of his boy cunt were just too much for me and I erupted into the condom and fell on top of him. I enjoyed the feeling of being inside him as the cum shot out of my cock and it slowly began losing its hardness and eased out of him.

We lay there in that position for several minutes. There was complete silence. Just the sound of our breathing. I rolled to Marcus's side and he moved the sticky pillow out from under himself and we began to cuddle and kiss each other.

Rosy's command broke the silence after a minute: "Marcus, you've made a mess on the pillow and our guest's cock needs to be cleaned."

Marcus rolled the condom off my cock, grabbed some tissues, wrapped it up, and threw it away. He then licked my cock clean of the residual cum that remained. After this he turned to the pillow and licked up as much of his own cum as he could. It was really a sight to behold a cum-eating bottom doing so much cleaning up after a hard fucking session.

After Marcus was done cleaning Rosy said: "Okay Marcus why don't you to go to the bathroom and clean yourself up" as she handed me a really luxurious silver coloured dressing gown. "I hope it is to your liking she said." And it sure was. "Let's go get some drinks and appetisers - you must be hungry!"

As chatted over refreshments, Rosy said: "Thank you for taking such good care of Marcus. You know he only likes to cum from his ass getting fucked. He feels guilty otherwise. And I have to discipline him because he could ruin himself through overly frequent anal masturbation with toys."

"I'm happy to fill the opening you advertised" I replied and we both shared a laugh "And I promise to work hard and not disappoint!"

"So was my presence a bother?" Rosy asked.

"Not in the least. I never thought I'd be able to do it with someone watching me. But you really know how to set the scene and make people comfortable." I replied.

At this point Marcus emerged from the bedroom and joined us for some drinks and snacks. We just hung out and chilled till I started feeling horny again. At which point Rosy said: "I will give you boys privacy for the rest of the night, I really enjoyed the show. Have fun!" and retired to her bedroom (she and Marcus often slept in different rooms, which did make sense, considering their situation with the open marriage, him being a gay bottom, and they not getting divorced because Marcus would stand to get disinherited if his conservative but loaded parents found out he was gay).

Marcus and I got back to his bedroom and this time I laid back and enjoyed a nice slow grinding fuck with him riding my cock cowgirl style. He also got hard again and came on top of my stomach as I ground away inside him. We fucked several more times, cuddled, made out, and fell asleep exhausted in the early hours of the morning.

Our playdate had once again become a sleep over.

But little did I know that Rosy was laying the groundwork for a serious erotic escalation.
