The engineers take advantage of the situation

As the engineers watch Morgan getting pleasured by the sex machine, they both glance at each other and smirk as the redhead was busy being pleasured by the machine. They both start disrobing themselves as the busty redhead moaned, hands gripping the handles tightly. It is revealed that both the engineers have huge schlongs of their own, both reaching down to their knees if they were flaccid but they proudly bounce up to attention as the are fully erect from the erotic sight being displayed before them. They both start to lube up their cocks as they approached Morgan's backside, one hand from each groping the buxom futa's curves.

Morgan gasped in surprised and looked back, her hips bucking into the sex machine as she does. She felt two hands exploring her body, one going down to cup her churning balls while the other clasping over her fat ass cheeks. The brunette who is cupping Morgan's balls crouches down next to the bucking redhead and begins to polish the futa's nuts. Her mouth opened agape and began to suck on that sensitive sack, her tongue sliding across the soft and sensitive skin. Meanwhile, the blonde engineer slid her hands between the redhead's cheeks. Her middle and index fingers began to tease Morgan's back door, pressing up against the sensitive muscle, feeling it twitch and react to the engineer's ministrations.

The blonde stopped for a moment to grab the lube that was used on Morgan's cock and lubed up her hand generously. She pressed her middle finger against Morgan's anus and pushed it inside. Morgan let out a soft gasp in between the moans, the whirring, and squelching noises coming from her and the milking machine. The blonde slowly fingered Morgan's ass meanwhile she was jerking off her own cock at the same pace. Each time her middle finger dove into Morgan, she reached for the poor redhead's internal buzzer and gave it a soft poke before retracting then adding a second finger. The blonde stretched out Morgans hole, adding in a third finger to really prep her for the blonde's fat cock.

The blonde pulled her fingers out of Morgan, who was getting overwhelmed by all the stimulation, and took position behind the redhead. She aimed her blunt cock head at Morgan's asshole and stuff the tip inside, both futa's moaned in pleasure but Morgan was louder as her cock exploded inside the machine and began filling up the jug beneath the machine. The jug was nearly full in less than a minute, gallons of white slimey splooge filling up the transparent container. Morgan slumped over the milking machine as she felt spent from the orgasm but the machine was still milking her cock for all its worth and the blonde behind her was still dead set on rearranging her asshole.

Morgan gasped, trying to speak up but every thrust the blonde made caused her to let out a groan instead of any intelligible words. Soon after, she felt the brunette's lips leave her now soaking balls alone and join her friend behind Morgan. The redhead looked over her shoulder to see the brunette was lubing up her cock as well. Morgan's eyes open wide as she knew what was about to happen next.

"Hold on, wait. I need to catch my breEEEEE~!" She squealed as a second cock slammed into her anus and stretched out her rectum. Her knuckles were white from how hard she gripped the handle bars. She could feel both engineers thrusting their cocks one after the other, the girth of them managed to hit every sensitive spot in Morgan's hole, the tips slamming up against her prostate.

The machine continue to jacking her off at a steady pace, not slowing down even once just as the two futa's behind the redhead refused to slow down either. As the fucked Morgan in tandem, they were making out in the most whorish and sloppy display a couple could make. Morgan could feel herself at the edge again, her cock once again spewing out a deluge of slimy sperm but the machine backed up and it flooded out the whole she was fucking and pooled around at her and the engineer's feet. The other two didn't mind or seemed to not care as they continued to duo ream out Morgan's asshole with wild abandon before they both let out moan in unison as they blasted their own creamy ropes deep inside Morgan's guts, filling her up till she looked at least 9 months pregnant. This triggered another orgasm from Morgan who's eyes rolled back into her head, more cum now pooling around the three futas.

Eventually Morgan was allowed to free herself from the fuck sandwich she was caught in and took a breather on a nearby chair. The other two futa's started cleaning up the mess they had collectively made before bringing in the massive jug of her own cum to her.

"Do you want to keep this or shall we?" The blonde asked, Morgan looking at the massive jug with her head flopped off to one side. Morgan stared at the jug, licking her lips.

"I'll take it, give it here." She reached out for the jug and took it from the two engineers. She opened it up and began to drink the whole thing till her cum gut hung low from all the jizz packed in her. The two engineers watching got hard from the lurid display, the blonde letting out a whistle.
