>>29873063Ren thrusts gently into Mysta, letting out small grunts and moans because of how tight he feels around Ren's cock. The contrast of his body temperature compared to Ren's is a sensation he's never felt before, and it's turning him on more and more the deeper he goes inside Mysta.
"Ahh....Ren....Ren!! Hahh....nhhh....Ren," moans Mysta as he grabs at Ren's back, not knowing what to do with himself as he is overcome with pleasure throughout his body. "Ren how- ah....are you......so big......hahh..."
"Sorry, am I hurting you?" asks Ren, barely able to stop himself from going deeper. Mysta shakes his head. "I'm almost all the way in."
Mysta's head is still dizzy from the sweet smell, the lust he feels for Ren, and perhaps even a side effect that may have come from being in contact with Ren's secretion. All he can feel is Ren's extraterrestrial phallus being pushed inside him and the cold feeling of Ren's heavy body against his. "It's in now," says Ren. "I'm gonna move now. I'm all the way inside." Mysta tries to respond but all he can do is clench tight around Ren's dick, eager to feel more of him. Ren starts moving back and forth now, moaning in Mysta's ear at finally being able to make love to the man who was the subject of his affection for so long. Ren softly bites down on Mysta's neck and starts sucking on it, resulting in Mysta throwing his head back and hissing in pleasure. The sensation of him sucking his neck and pushing back and forth inside him makes him unable to hold back his voice. They're getting stronger and stronger and Mysta's hands are trying to find a comfortable place to grab onto. Mysta starts clawing at Ren's back as he's feeling him more and more, getting closer to Ren's ear and neck and moaning into it passionately. Mysta's erection was rubbing against Ren's stomach as he thrusted, heightening the sensations throughout his body and causing him to grab more parts of Ren's chilly body to contain the feelings. He grabbed one of Ren's horns, to which Ren let out a strong hiss of pleasure.
"HSSSSSSH AHHN!!!," snarled Ren. "Aghhnnnn....hnnghhhh......."
"Ahh...wh-what's- ahn....wrong, Ren?" asked Mysta between moans.
"Those are....very sensitive. And touching them a certain way triggers some....bodily changes. I don't think you're ready to handle that just yet." says Ren while continuing to thrust inside Mysta. Mysta felt the size and possibly the shape of Ren's penis change when he touched his horns. He also thought he saw a part of Ren's shoulders and back change color a bit, but he was too dizzy from the pleasure of sex to really make out what it was.
Mysta's hands moved down to Ren's back and started to scratch at it, the passion of their intercourse getting stronger as Ren held Mysta more tightly. They're both moaning loudly almost in each other's ears at this point, and the scratching makes Ren thrust even faster. As Mysta's moans get even more high pitched and wild he loses control of where his hands are grabbing, switching between Ren's back and head. Ren's left hand makes it's way up Mysta's body and intertwines his fingers with the detective's, but the other hand is still trying to grab at something, and Ren is using his right arm to hold Mysta's body. Mysta grabs one of his horns again, this time getting a few fingers between the spike-like parts sticking out from it. Ren lets out another strong hiss of pleasure at Mysta touching such a sensitive spot.
"HNNGHHH AHHH, MYSTA!!!" shouts Ren, burying his teeth into Mysta's neck to try and contain himself. He can't hold himself back anymore and starts thrusting faster. Just when Mysta thought Ren couldn't get any bigger, his phallus grows even larger inside him and hits his prostate at the perfect angle, making Mysta roll his eyes back and go completely limp at the overwhelming pleasure he feels, completely missing out on seeing strange, small extremities grow out of Ren's back.
"Mysta.....y-you shouldn't have done that," whimpers Ren, now sounding like he's about to whine because the pleasure he is feeling may be overwhelming for him too now. "I.....I think I'm about to....r-realease....aahhhhh!!"
The only way Mysta can respond is through loud moans. Ren lets go of Mysta's hand and grabs both of his thick thighs, pushing them back almost against the bed and pumping as deep as he can inside him, releasing a very thick goo that flows all throughout Mysta's insides. Mysta cums as well after having his prostate hit in such a perfect spot so many times and scratches Ren's back extra hard at the overwhelming bliss and satisfaction he feels at releasing and letting out one final sensual wail.
