S3x With Libra: Gravitational Tightness

(Jason's POV)

"Damn." I said as I held Libra by her waist, "You're so fucking tight." 

I laid on the bed as Libra was on top of me, riding me cowgirl style. Her pussy clamped on my cock as I moved her hips up and down. It felt so fucking good, especially since my cock was sensitive from cumming to her blowjob. 

Libra pressed her body on me as I moved her hips up and down, my cock going in and out of her tight pussy. 

"Ohhh~~" She moaned loudly, "Your cock is so big...." 

"I know." I said as I began to move my hips as well, "Your pussy is so good, Libra." 

I began to fuck her as I moved her hips, clapping her ass on my thighs loudly. Her pussy walls clamped tightly on my cock as I thrust into her deeply. 

"Ahh~~~" Libra moaned as I slapped her nice and meaty ass, "So good!!" 

"Yea, I know it's good." I said as I kept fucking her hard

I thrust my cock up into her pussy as Libra began moving her hips on her own, slamming her ass on my thighs, clapping them louder than before. The tip of my cock began kissing her womb aggressively as Libra rode me nice and roughly. 

"Ohhh~~~" She moaned loudly

"You like it?" I asked

She nodded, "Yess!" 

I chuckled, "I like this too." I said, "Your pussy is so fucking tight, I'm not even gonna lie. It's like it's perfectly molded for my cock. It's so fucking nice and snug, godamn." 

Without saying a word, Libra leaned in and kissed me. I was taken a bit aback by this, but I still kissed her back. Our tongues wrapped violently around each other as I wrapped my arms around her tightly as I fucked her. Her pussy tightened even more on my cock and the sensation of it going in and out was so fucking good. 

Libra then pulled back, saliva dripping from our mouths. 

"I love your cock..." She said

"Good." I said, "Hey, lean back. I want to see your beautiful breasts bouncing up and down as you bounce on my cock." 

Libra leaned back and began to bounce on my cock, up and down as she leaned her head back in pleasure. 

"Ohh~~" She moaned loudly 

I watched her massive breasts bounce around as she rode me vigorously. Her tight pussy was clamped on my cock so good that it felt good every time she even moved. 

I reached up and grabbed her breasts and gave it a good squeeze, causing her pussy to tighten even more. 

"Fuckk...." I said, "Your pussy is too tight, gah!!" 

It was true, I am not sure what was the cause of it, but her pussy was tightening up even more than usual. Was this somehow, someway, the effect of her magic? I know that she uses gravity magic, like Kagura, but Kagura didn't do this at all. Then again, Libra is a Celestial Spirit, so similar to Aquarius and Aries, there's some traits of their magic that appear on their body in some way. 

"Keep riding me like that." I said, "Just like that, Libra." 

Libra kept riding me as her breasts bounced up and down while I groped them, squeezing them like her pussy squeezed on my cock super tight. The amount of pressure on it was so much that my cock was bulging viciously. Only reason I hadn't cummed yet was because the sensation of it was so good that I didn't want it to stop any time soon. 

"Fuck." I said as Libra bounced on my cock

"Ohhhh~~~" Libra moaned, "Jason~~~" 

She kept going, didn't stop one bit. The pressure her pussy was exerting on my cock didn't stop either, it was beginning to hurt but in a good way. I didn't think I was capable of enjoying this odd pain, but man, was it making me feel good. 

"Fuck!" I said as I held her by her waists

I watched as her massive breasts bounced around as she kept riding me. 

"Jason!!" She moaned, "I'm cumming!!!" 

"Okay." I said, "Together, then. I'll fucking creampie you." 

Libra's pussy tightened even more as I felt her body shake. 

"Ahhhh~~~!!!!!" She moaned loudly as I felt her cum on my cock

I then released a massive load of cum inside her. The amount of relief I felt was unimaginable, it was like I was relieved of a great pressure. It was like a backed-up pipe releasing it's pent up water, relieving itself of it's pressure that was meant to burst at any moment. 

I felt as Libra laid on me as I felt her pussy tighten on my cock as I pumped semen into her. She was trembling slightly as she panted. 

"Ohh...." she moaned 

"Fuck." I said

I felt the massive amount of semen pouring out of her pussy and onto my cock. I slowly pulled my cock out of her pussy, feeling an odd sense of relief. 

"Ah..." I said, "Damn." 

Libra looked at me, "Was..." She started, "Was my pussy good?" 

I nodded, "Yea." I smiled, "It was amazing."

"Holy shit."
