My wife Tina and I are in our early thirties. We were Highschool sweethearts and got married right before we went to college. Tina's best friends, Debby and Chloe had also married their Highschool boyfriends. The three of them shared everything and had no secrets from each other. We, the husbands of course knew this and so we assumed that they knew everything about us.
One day when the three of them were together again my wife Tina asks Debby and Chloe, "Have you ever wondered whether your husband has homosexual tendencies?"
"No, why do you ask, Fred is totally straight. Do you suspect your hubby Frank," Debby answers.
"No I don't, just wondering. What about yours, Chloe?"
"Mike, definitely not."
"Well, the other day I looked at Frank's computer, he had forgotten to erase his browsing history. I found no gay porn, but a lot of cuckold porn. Do you think they are into that?" Tina asks.
"There is an easy way to find out about both of these questions," Chloe chuckles, and so the plan is hatched.
Next Saturday afternoon everybody comes over to our house to hang out and drink beer. The mood is pretty relaxed when Tina suddenly announces, "Let's play a game. The girls want to know how straight their husbands really are and we will test that."
Stunned silence.
"How?" Fred finally asks.
"Easy, the guys strip naked, sit on a chair in front of the TV and we play gay porn and see what happens. An erection will be proof that you are into gay stuff."
"I don't think so," I protest.
And I know why. I have been watching gay porn in secret. Not because I want to have gay sex. I just find naked young athletic males arousing to look at.
"Don't spoil it for us, Frank. You got nothing to lose," Chloe counters.
The girls remove the coffee table and put three chairs in a semi-circle in front of the TV.
"Strip naked boys," Tina commands.
Reluctantly, we all strip and sit down awkwardly.
I look at Mike's dick. Six inches not too thick, nicely circumcised, similar to my own except I still have my foreskin. I look over at Fred's crotch. Unbelievable, hung like a horse, eight inches, quite fat, circumcised, smooth. If that thing becomes erect I'm in trouble. I always fantasize about sucking a nice big cock like Fred's.
"Debby, you weren't kidding about Fred's cock. The pictures you showed us aren't doing it justice. Can't wait to see that thing in its full glory," Tina says in awe.
"You were showing Tina and Cloe pictures of my cock," Fred asks incredulously.
"Of course we were, there are no secrets between us. Let's start the show. Frank, give me the URL and password of your favorite porn site, and don't tell me you don't have a subscription. I see the monthly charges on the credit card bill, even though they try to hide that it is a porn site. The site is called Pornhub."
What choice do I have? Tina types the URL and password into her iPad and streams it to the TV set.
"Alright, here we go, three categories, straight, gay, transsexual. We'll keep transsexual for another day. Gay, what shall we pick? How about young guys, twinks, taking showers," Tina muses.
A young guy in his early twenties comes on the screen. He is handsome, athletic, well built. He slowly takes off his clothes and steps in the shower. He has a huge cock hanging between his legs. He slowly starts soaping up himself. He runs his hands over his toned body and eventually soaping up his magnificent cock. It rises to half-mast. I'm in trouble, I feel my cock stirring between my legs. I look back at the screen. A second young male enters the bathroom. Also a beauty. He takes off his clothes and joins the other in the shower.
They start kissing passionately. Their cocks rise to full attention. There is no room between their bodies for the cocks to expand. They are being pressed sideways rubbing against each other. The twins step back a little and start jousting with their rock-hard cocks. It is too much for me. I'm fully erect now.
"Frank is the winner. Look at him, fully erect. Look at Mike, almost erect. What shall we do with them?" asks Chloe.
"How about Frank gives Mike a BJ or handjob," Debby suggests, "I'll flip a coin, heads is BJ, tails is handjob."
She flips a quarter.

"BJ it is."
Tina walks up to me roughly grabs my erect cock, pulls me off the chair, and pushes me in front of Mike. She grabs my hand and firmly pushes it against Mike's semi-erect cock. I'm so horny now, I just want to suck his cock into my mouth. I look at Mike's face. He is beet red but says nothing. I grab his cock and squeeze it. I feel it expanding in my hand. I guide it towards my mouth and slowly suck on it, my tongue circling his cock head. I suck on it like a lollipop. The room is deadly silent, the only noise is my slurping on Mike's cock. Mike starts breathing heavily, now groaning louder and louder. His body starts convulsing. He shoots his load, tons of it, never-ending down my throat. I start choking.
"Absolutely beautiful, amazing."
The girls are cheering and clapping.
"Swallow, swallow, swallow," they keep chanting.
I gulp down the whole load.
"Whow, that was interesting. Frank, definitely interested in the boys. I have to watch out for those young studs. Mike, for sure interested. Fred, not so much," Tina summarizes the results.
"One more test, though. Frank watches a lot of cuckold porn. Let's see whether he is turned on by watching his wife fucking another man."
"But he is already rock hard," Chloe objects.
"If he is turned on he will stay hard, if not he will be limp shortly. Excuse me for a minute," Tina counters as she leaves the room.
A minute later she returns. Everybody gasps. She is wearing a tank top that barely covers her big pendulous breasts, complemented by lacy panties. She is carrying a blanket, spreading it out on the floor. She walks up to Fred moving seductively around him. Standing behind him, resting her heavy rack on his head, her hands are roaming his chest. Fred's enormous cock starts to rise. Tina walks around him, lowering her lacy-clad butt to the tip of his now fully erect cock, wiggling around. Fred starts to moan, precum forming on the tip of his penis. Tina grabs his cock, pulling him up from the chair, moving to the blanket. Slowly she takes off her top. Her breasts bounce freely. Off come the panties too exposing her neatly trimmed pussy. Kneeling in front of Fred, she engulfs his giant manhood.
"Frank is still hard, so he really likes this," Debby observes.
Tina smiles at me motioning me to come up to her. I walk up, standing next to Fred. Tina grabs my cock with her left hand, holding Fred in her right. Sucking and slurping, alternating between both cocks. Tina pulls on both cocks, forcing Frank and me closer together.
"Look at the size difference. Unbelievable," Tina exclaims.
She starts slapping my cock on Fred's, pushing their heads against each other, jousting, a sword fight.
"Just like in the video," Tina giggles as she pushes both cocks into her mouth. I feel Fred's cock head rubbing against mine in Tina's well-lubricated mouth.
"I won't last much longer," Fred groans.
"I need to fuck you. Never had a thing this big inside me," Tina mumbles as she lays down on her back.
I sit down cradling Tina's head in my lap, my erection sticking straight up next to her ear. I softly massage her tits while Fred mounts her.
"Fred, take it easy and slowly, she is not used to a thing like yours," Debby points out.
"She can take it, look how wet she is," I reply.
Fred slowly enters her. Soon both are moaning and groaning.
"I'm going to come," Fred grunts pulling out.
The first squirt, and it is huge, hits me straight in the face, the second hits Tina's face and hair, the third hits her chest. Fred now is dribbling on her cunt. I quickly jump up, pushing Fred to the side, I enter Tina. Her hole is huge and slippery. I slide back and forth, our two bodies lubricated by Fred's come on her chest and stomach. I kiss Tina deeply, only to taste Fred's load. Tina screams in ecstasy, I come hard inside her. There is complete silence.
Finally, "Frank, you certainly have interesting tastes," Debby mumbles.
"Hey, this was fun and good entertainment for a dreary Saturday afternoon. We'll think of some games for next time. Now boys, go home and fuck your wives," Tina says matter of factly.
This was the beginning of many fun afternoons.
