S3x With Ophiuchus: The Back Door

(Jason's POV)

"Damn." I said as I laid on the bed next to her

"Hm." Ophiuchus said, "I must say, your cock definitely felt good inside me. If it wasn't for the urgency, I'd definitely let you pound my pussy for much longer than now." 

My head was a little light, I couldn't exactly focus on what she had said. 

"Uhuh..." I said 

"Wow." I heard her say, "You definitely filled me up. My womb can't take all of this cum at once. But it's fine, since I can't get pregnant." 

"Yea..." I said as I stared at the ceiling

I can't believe that the serum did this to me. I don't know how to feel about it. Normally, I can last for hours before cumming once. But now, I didn't even last a damn minute. How fucking humiliating this is for me. 

But for some reason, it didn't make me mad. I wonder why that is. Maybe it was the drug she gave me. This isn't the first time my emotions have been tampered with. 

"Worry not." Ophiuchus said, "I'll clean your dick." 

I then watched as she leaned over to my cock and began to suck it clean off. I felt as her tongue coiled tightly around my cock as it moved around it. I felt my cock get harder, I was surprised this was even possible due to the amount of semen I had unloaded inside her. 

"Damn." I said, "Whoa...is your tongue....longer than usual..." 

Yea, I felt her tongue had coiled around my cock like two times around my cock. That wasn't normal for a regular sized tongue. 

Ophiuchus took my cock out of her mouth and I watched as her tongue hanged from her mouth, it was ridiculously longer than normal. 

Oh, I get it. It's because she's a snake. Okay that makes sense.

"Isn't it quite useful?" She said as her tongue went back inside her mouth, "I can give the best blowjobs you can imagine."

I slowly nodded, "Sure." 

She then slapped my thigh, "Okay, up you go." She said, "We're not done." 

"I don't think I can cum inside you any more." I said, "I feel drained." 

"But you're not." She said, "Your cock is super hard now. I need another massive load inside me."

I slowly sat up and looked at her, "Hm..." I said

She patted my cheek, "Worry not, Jason." she said, "I promise you that we will have proper sex in the future. For now, this is of great urgency." 

I sighed, "Fine." I said, "I'll take you on that promise." 

She smiled and took the entirety of her outfit off, revealing her nice and voluptuous bare body. She then bent over and raised her ass to me. I then watched as she placed her hand above her anus.

"Come here." She said

I raised an eyebrow, "Huh?" 

"What?" she asked, "Never done anal? I need another massive load inside this hole too." 

"I...." I said, "I never had anyone want it in their ass." 

"You're joking." she said, "All these women you've fucked and nobody wanted it in their ass? Man, they sure are boring. Now, hurry up. Put it in. I assure you, you can last at least a minute before you unload your semen inside me." 

I sighed, "Okay." I said, "If you insist." 

I then slowly put the tip of my cock inside her ass. It felt so damn tight, I never expected it to be this tight. It's tighter than her pussy. 

"W-Whoa..." I said

"Just jam it in there, It'll go in." she said, "Don't worry." 

I then grabbed ahold of Ophiuchus's fat ass as I rammed my cock deep inside her asshole. 

"Fuck." I said

"OH~!" She moaned loudly

So this was anal sex, huh? It was so much tighter than her pussy, holy shit. I then began to move my hips as I gripped her ass-cheeks tightly. 

"Yesss~~~" Ophiuchus moaned as I fucked her ass

"Fuck." I said

As I moved my hips, my cock could do nothing but twitch violently. I think this has to something to do with the damned serum. 

"Shit!" I said as I felt a massive load coming, "Fuck!!" 

"Yess~~" Ophiuchus moaned loudly, "Just release it inside!!" 

I felt a massive load of semen burst out of my cock and into her ass. I gave her a massive thrust as her ass-cheeks clapped loudly. I felt my entire body shake in pure pleasure as I looked up at the ceiling. 

"Fuuuuuckkkk...." I said as I felt semen pour out of my cock and into her asshole

"Yess~~~" Ophiuchus moaned, "That..is good...." 

I then slowly pulled my cock out and watched as a massive pool of semen poured out of her asshole. I can't fucking believe this bullshit.

"Damn." I said

It was my first time doing anal and I couldn't last for shit. This was not a fun thing for me. Fuck all of this bullshit. 

I laid down on the bed, the amount of semen that I had released wasn't as much as earlier but considering that it was back-to-back, my body needed a breather. I couldn't help but just lay down. My body felt heavy and light at the same time, it felt like I was going to sink into the bed. 

"I greatly apologize, Jason." Ophiuchus said as she began to lick my cock clean, "But with that massive load...." 

"That makes two holes already~"
