The product gets rushed to testers

Due to the pressure from management and the shrinking budget, Dave and Eve were **** to fast-track the lube to market. The tester received a small package of the lube and a piece of cardboard where the portal would appear after the lube had been applied.

The size of the test group was just over 50 people and the goal was to see if there would be to see if there would be problems with the pairing of the lube to the paper or cardboard that would be the carrier for the portal.

The samples got sent out on a Friday and Eve and Dave packed up the last few packages before heading out for the weekend. They would take the breakthrough as a reason to head for a secluded cabin in the woods to relax from the stress of the past months.

They arrived at the cabin a few hours later and noticed that the reception was nonexistent. This was by choice however to focus on relaxing and not on research and what the testers found out over the weekend. They spent the evening together while cuddling in front of the fireplace. Of course, they got handsy after a while and made out right there on the floor.

The evening ended in passionate sex and they fell asleep while embracing each other's bodies.

The next morning, Eve was waking up to the feeling of a finger pushing into her ass. She smiled and felt herself get wet. She smiled as she let out a quiet breathy moan but didn't turn around. The finger pumped in and out of her hole. Eve felt the finger wiggle around in her asshole and then it was pulled out. She felt the head of Dave's cock press against her ass and she relaxed herself. The cock was pressed inside of her ass and Eve let out a breathy moan. The cock pistoned into her ass and Eve really got into it. The fucking continued but Eve couldn't help to notice that other than the fucking Dave didn't touch her body like he usually does. She supplemented the missing hands by pinching her nipple with the one and hand rubbing her clit with the other. The fucking got slower and Eve realized that Dave was about to cum. She tightened her ass to increase Dave's pleasure. She heard a snore behind her back. She turned her head and saw that Dave was still soundly asleep, lying on his back.

Eve panicked. Who was fucking her? Did somebody use the portal they left in the lab?

She sat up to wake Dave and felt the cock cum in her ass. The cock retracted from her ass and she felt the cum slip past her lightly used sphincter. She pondered what to do when another cock pushed itself into her ass. She gasped, still horny from the fuck she thought was with Dave. The cum on her sphincter aided the second cock as lube and the penetration was very pleasurable for Eve. She always had a thing for anal. The cock sped up in her ass but then Eve felt another cock enter her asshole.

Now getting fucked in the ass by two cocks at the same time, she woke Dave up and explained the situation. It was getting increasingly difficult to talk because of the stimulation in her ass and the feeling of two cocks going ham in her ass.

Dave and Eve figured that there must be a problem with the samples they sent out to the testers and that they witnessed the first testers try out the prototype portals. For whatever reason they are still linked to Eves asshole instead of the place the lube for the testers got applied.

They still had no phone reception and the next city was a two-hour drive away. They couldn't contact anybody to contact the testers and make them stop.

When they finished the conclusion the other two cocks had ejaculated in her ass and got replaced by a single new cock.

By now, Eve's asshole was quite raw after roughly an hour of continuous anal sex. The only lube she received was the cum of the cocks slowly leaking out of her ass and coating the cocks as they fucked her.

The single cock that came after the two simultaneous ones had difficulty cumming because just getting fucked by two cocks at the same time made Eve's asshole dilate quite a bit. The cock retracted halfway and Eve felt a vibrator getting pushed through her anal rim.

The fucking continued and with the added vibration and tightness of the vibrator, the cock in Eve's ass didn't take long to cum. The cock left her asshole but the vibrator was left inside. Eve got frustrated by the vibrations because it kept her on edge but wasn't enought to make her cum. She also feared that it would be forgotten inside of her and that it would deter the next cocks trying to fuck her asshole.

Her fear was confirmed with the next cock. She felt something cold drip on her ass and a new cock pushed through her loosening asshole. It jerked back as it touched the vibrator and the cock was hastily removed from her ass. After that, Eve was left alone with the vibration again. The cock that gifted her lube didn't return.
