SCP-682 had breached containment and made its way through an elevator shaft from the depths of the containment facility. The upper levels had been evacuated to avoid any loss of personnel, but many items were left behind. A mobile task force was on their way to reestablish containment.

SCP-682 made it to the end of the elevator shaft and pried apart a set of blast doors that blocked its way out. Then, 682 found itself in a hallway which it moved through. It was now in the rest of the facility which was still mostly underground.

He navigated through the facility which was like a maze. 682 would go through many doors with the hope it would lead further to the outside. It stumbled upon empty test chambers and the containment cells of inert items in his pursuit until it broke into the containment area of SCP-811.

SCP-811 was outside of the water of her enclosure. She was listening closely to the distant sounds of SCP-682's frantic search for an exit, and she was also observing the red alarm lights blink behind the observation windows of her glass enclosure.

She staggered backward when 682 barged into the chamber, breaking a small section of the surrounding glass. The chamber quaked in 682's presence and 811 was still. 682 caught sight of the swamp woman. Her black oily hair partially covered her face.

682 briefly stared at 811. He looked at her long legs to her bare breasts and started to feel... aroused. It had been a while since it had anyone.

SCP-811 smelled the air and caught a whiff of a warm scent that started to replace the usual methane that was present in her chamber. It was oddly arousing and came from 682.

682 quickly reached out and grabbed 811 by the waist, and it had her facing him. She kicked her long legs out at 682 in an effort to escape but stopped for she started to feel relaxed, warm, and herself slowly growing wet.

682 then started to form a visible penis which exited from its reptilian body. It quickly grew larger, longer until it was fully erected. It twitched in anticipation. 811 looked at 682's penis and grew wetter. It was veiny and would pulsate.

682 grew an additional set of arms at the front of its body as it placed another hand on 811's waist to get her closer to his penis which was dripping with precum. It placed the head right outside of penetration. The precum felt warm and 811 had spread her legs apart. She was breathing out a bit of warm fog. She wanted it inside her. It was all she could think about.

"P-please..." 811 begged in a low, cute voice.

682 then thrusted forward a bit into 811. It was not even halfway in and 811 was losing it. She rolled her eyes back and stuck her tongue slightly out. Her body was tensed up from the brief pain and the joy that came after. Her mind was filled with ecstasy. The only sound she made were small soft moans as she felt 682 twitch inside her. 682 released a loud groan for 811 was tight. The glass of the enclosure then became fogged up while 682 breathed.

Again 682 thrusted, making 811 squirm and produce a small yelp. Her ass was clapped by a thick gel that covered the penis, along with a set of dangling testicles which normally were inside 682's body.

For 811, this was the greatest experience so far in her life. She would sometimes rub her clit or use the handle of her hair brush provided by the Foundation but none of those came close to the pleasure she was experiencing at that moment.

682 continued to thrust once 811 was no longer in shock from the initial penetration. 811 loudly moaned with every thrust, her face blushing noticeable due to her green skin. She tried to have her legs wrapped entirely around 682 but couldn't due to its massive size. 682 removed one of its hand off 811 to keep itself more balanced. It was feeling light headed from how the walls of 811 tightened and became more moist.

682 extended out its slimy tongue which slithered its way down to 811 beneath it. It entered its way into her mouth which surprised her before relaxing again. She closed her eyes and licked back at 682's tongue, making muffled moans. This made 682 groan louder.

682 then moved its body upward to have a stance like it was sitting. It continued to thrust into 811 but once it was upright, it moved 811 to face outward from it while she was still on him. She groaned, which was muffled from 682's tongue, since she felt 682 twist inside her when it did that but it made her more excited. Then, she received further thrusts that lead to her getting clapped more. In this new position, one could see the slight bulging stomach 811 had was larger than usual and had the faint outline of 682's penis as it went in and out.

682 then grew two appendages from its torso that reached out and played with 811's breasts. At the end of the appendages were suction cups that had a tongue inside that latched themselves onto 811's breast, licking her while the rest of the appendage wrapped around her breasts to move them around or occasionally squeeze them.

After a while, 682 retracted its tongue from 811's mouth and started to move faster for it was getting near its long awaited climax which it needed for a long time. 811 was also feeling the need to cum herself and loudly moaned with every push toward bliss. 682 ended with one final hard thrust which made 811 shriek out in pleasure for she received her first and ultimate creampie that she would ever have in her life. 682 groaned loudly than before once he came, releasing lots of slimy sperm into 811, which all came pouring out once 682 pulled itself out. 811 convulsed from her climax but proceed to cum again due to how great the first one was while she was dripping sperm, and drooling saliva.

The two creatures then laid in their own sweat and other bodily fluids on the floor of the enclosure. The room was hot and every piece of glass nearby was fogged up. 811 crawled up to 682 and cuddled with the beast before falling asleep with a smile on her face. Unfortunately, 682 sensed that a mobile task force were arriving on the floor from the rest of the site, so it couldn't stay to cuddle with his new mate and perhaps go a second round. It gently rose and left the chamber, leaving 811 in a pool of cum.
