"So after I finally got free of Pup's knot and she drained me a bit, we went in to help you." Rena said. She stood naked with her legs spread as she bent over and reached for her right foot. "Of course, that Fran girl didn't need our help at all."
"Yeah." Pup nodded. "After we pulled your dick out, she just flexed her abs and all of your cum came spraying out of her like an open fire hydrant. It was awesome."
"Then she grabbed her clothes and left without even saying anything to us." Rena shifted over to her left foot.
"Huh." Umi was sitting naked on the bench next to Pup, gently playing with her half erect cock.
Rena straightened up, put her hands on her waist, and started gyrating her hips.
"You've been at half-mast all day." Pup said as she reached over and started stroking Umi's cock.
Umi nodded.
"I couldn't even get my cocksock on this morning." Umi sighed as Pup gave her a strong squeeze. "I can't stop thinking about fucking her."
"Awww!" Pup giggled as she let go of Umi. "Sounds like you have a crush."
Umi paused for a moment as she thought about it, then turned bright red and stared at the floor.
"I... don't know..."
Pup's face lit up with a huge grin and Rena had to turn away, trying not to laugh.
"Well, maybe you'll meet her again. For now, I'm ready." Rena said as her urge to laugh subsided. She put a knuckle to her chin and popped her neck, then did the other direction. "Okay, let's do this."
"Wow, you really just did a full body stretch to prepare for her dick." Pup said.
"Yeah." Rena nodded. "It's a full body dick."
Pup paused for a moment.
"Huh. Fair enough."
Rena walked over to Umi and grabbed the head of her dick. Umi's cock tingled as Rena's fingers slowly massaged her glans. "Since you're already to big to stuff it in like you did to Pup, I'm just going to mount you."
Umi nodded and scooted off the bench, laying on the ground. The floor felt cold to her body after being in a constant state of arousal all day.
"I brought my mat if you want to use that." Pup said as she waved the bundle.
"Y-yes please." Umi got up as Pup rolled out her mat and she laid back down on it. It was far more comfortable and distinctly smelled of semen, which only made Umi more aroused.
Rena laid down between Umi's legs and started playing with her balls. They were already bigger than usual, and she wondered what she should do to get Umi fully erect. Rena saw what she wanted to do as lifted Umi's heavy testicle.
"Eeep!" Umi squeaked as Rena's fingers suddenly grabbed her clitoris. She was gentle, softly squeezing and stroking her hard, pink clit and delivering a constant barrage of toe-curling stimulation that quickly had Umi moaning.
"Wow, your clit is really sensitive." Rena said, wondering if she has just found Umi's weak point. She started to apply more pressure, pinching and squeezing, and Umi's reaction only became stronger.
"Haa... Haa... Hnnn! Nyaaa!" Umi twisted and jerked, but Rena gave her no mercy. She had no idea how to handle the stimulation as it overwhelmed her.
Rena finally stopped, and Umi was left panting and trembling. Her cock throbbed and her pussy was soaked. Umi was not used to having her clit played with. Whenever she fucked, the focus was always on her cock. Even when she was bored, she would suck herself or sit on a vibrator while playing on her computer. With her clit being hidden behind her oversized testicles, it got so little attention that it had become very sensitive.
Before Umi could even collect herself, Rena was already straddling her dick with her glans in her pussy, giving her no time to cool down. She was easily halfway to an orgasm, and Rena's tight little pussy was only getting her there quicker.
Rena's stomach began to bulge with Umi's cock as she lowered herself even further. She could feel her body heating up as Umi's girth opened up her insides. Her dicks were twitching, and as Umi's cock burst through her cervix her left dick blew, splattering Umi with a coat of thick hot semen.
"Damnit." Rena gasped. She felt a bit annoyed that she came much sooner than Pup, and she could not take as much of Umi's dick. Pup took just over half while Rena could not even hit the halfway point. With Umi lying on the ground and her dick as deep as Rena could take it, Rena still could not touch the ground with her knees and had to squat. She had really underestimated the size, and having such a thick cock wrench her cervix open was making her really sensitive.
"Hey, you said your dicks cum separately, right?" Pup asked as she crouched down in front of Rena's dicks. She sat on Umi's stomach facing Rena, and Umi reached around and began stroking and playing with her wet slimy dog dick. "Oh? Mmm... That's nice."
"Yeah." Rena answered as she settled Umi's glans inside her womb. Slowly and bit by bit, she relaxed her legs until a majority of her body weight was supported by her womb. She shifted around until she found a good balance, then braced herself and tightened her core. Rena exhaled and lifted her legs completely off the ground leaving her suspended in the air, held up by nothing other than Umi's massive cock. "I did ieeeeee-t!"
Pup opened her mouth as Rena's right dick erupted in her face. She wiped some of it off and swallowed the rest. Rena dropped her legs and caught herself after cumming harder than she expected.
"That was a nice one." Pup said as she wrapped her mouth around Rena's right dick, sucking out the rest.
"T-Thanks." Rena shuttered as Pup suckled her sensitive dick, then released it. "I wasn't sure if Umi's cock was strong enough to hold me up, but it definitely is."
Feeling a bit more adjusted to Umi's dick, Rena started rocking back and forth, her golden twin tails swinging with her. Pup planted her arms and lifted her hips, grinding her pussy and balls against the exposed lower shaft. Umi braced herself, but she could handle it. Rena was not moving very fast and Pup's added stimulation was manageable, though Rena was starting to get more into it.
"Mmm... So, your dicks." Pup said.
"Y-Yeah?" Rena hazily replied.
