My gf (Jessica/Jess)) has a twin sister named Jennifer/Jenny. When I first started dating Jess, I would get them mixed up from time to time. They even played jokes and or pranks on me, but after a month or so, I caught on. After dating Jess for a year and a half, we moved in together and shared an apartment. We used to work together, but then I got a better job.

When Jess said her office was having a Halloween costume party, she invited me as I still knew some people there as I left on good terms. Her sister Jenny also tagged along. We all met up at our place before we all headed out to the office party. Jess dressed up as a nurse and myself as a doctor. I think Jenny went as a witch. It started around 7pm and there was food and drinks, dancing, trivia and several other activities. It started to die around midnight. Jess and I took an Uber home as we were too drunk to drive home. Jenny said she’d find her own way home so we just decided to go out separate ways. When we got home, I was tired and was ready to hit the sack. Jess wasn’t too sleepy, but she was concerned about Jenny and said she was going to go check on her because Jenny wasn’t answering her phone. I asked Jess if she wanted me to come with her, but she said it was fine.

I was awoken later by Jess coming into bed around 3am I think. I asked if everything was okay and she nodded yes. But she said, “Babe, I’m horny. Will you fuck me before going to sleep?” I was never one to say no, I just said, “Okay. Just let me get more awake…” I started to rub my eyes and sit up a little. I yawned and pulled the blanket off. It was still dark ss we left the lights off.

Jess wasted no time, as I was just starting to get up, she pulled down my shorts and started to suck my morning or evening wood? Jess was moaning while sucking and I could feel her swirling her tongue around my tip and jerking my shaft hard. I started to undress her and let her have her way with me and my cock as I was already hard. I gently slapped her ass and played with her holes making her moan louder. As Jess continued, I felt the pressure build up inside me and felt some precum ooze from my tip. My cock was throbbing hard and pulsed. I let Jess know as I told her, “Oh shit!…fuck, I’m about to cum!” I felt my legs get tense, my face turning red and I flexed my body as she just continued until I finally released my load of my warm sticky cum into her mouth as she swallowed my entire load draining my balls, milking me as she cleaned off my cock. I felt bad for losing my erection after cumming, not being able to give her what she wanted. So I got between her legs, but I teased her at first. I started to kiss and lick, with some gentle nibbles on her inner thighs. She started to squirm, so I held her belly down with my hands as her legs were over my shoulders. She begged for me to eat her out, but I teased her some more. But eventually, I started to eat her tight little pussy/clit making her more wet as she was already horny and wet from sucking me off. She continued moaning louder and louder mixed in with some whimpers. I was going to make Jess cum from oral just like she did to me as I gave more attention to her sensitive wet clit. Jess started to writhe around in pleasure, her body trembles, arching her back out and started to scream out, “Oh fuck!…mmhmm….Right there! Yes, yes just like that!…Keep going!…oh yea! Uh-huh…aaagghh!!” Jess screamed out after cumming with her legs quivering and her toes curled. Jess usually convulsed instead of her legs shaking, but I went with it as I thought I just did a good job.

When my erection was back, I got between her and I began to fuck her raw as I knew she was on birth control. When I started fucking Jess, I noticed it felt different but felt so good. So I just continue pounding away on her tight shaved pussy. Getting soaked, Jess was moaning loudly, whimpering and whined as I buried my cock deep inside her pussy, giving her hard and forceful thrusts of my cock filling her little tight pussy. Fucking her in multiple positions, missionary, cowgirl, reverse cowgirl, doggy, and spooned her with reckless abandon like an animal, my primal instincts kicking in. While I fucked her good, Jess was screaming, “Oh shit! Fuck!…That feels so good!…please, keep going! Yes just like that!…ugh…Don’t stop!…don’t stop!” I was in doggy, my balls swinging slapping against her clit which made her scream. I started to pull her hair, slapping her ass, then I was holding her hips from behind ramming my cock into her pussy, clapping her ass and giving her backshots, going to pound town. Once I felt pressure build up once again, I told her I was about to cum. I could feel my cock starting to throb hard. I once again felt precum oozing and my pumps became slower, but still balls deep in her dripping wet pussy as my cock was also pulsing. “Mmm….fuck…I’m about to cum!…” I said. I flipped her over getting Jess in missionary. I started to tense up again, my grip on her hips tightened. Jess didn’t reply, she was just moaning in ecstasy as she threw her head back. So I came in her pussy shooting ropes of my warm sticky cum filling her up draining my balls inside her, my cock was pulsing and throbbing inside her pussy milking my cock dry for the second time. After we fucked, we cuddled a bit, caught our breath and decided to clean up a bit then sleep.

It was at this point I got a good look at Jess in the bathroom, and thought to myself a bit. So I decided to just throw it out and I asked, “Ugh….Jenny?” She replied, “Yea…it’s me, Jenny.” My stomach sank as I felt sick to my stomach. “You can’t be fucking serious! Is this some kind of a sick joke? Are you trying to ruin my relationship with Jess? What the fuck is wrong with you! Do you want us to break up?!” I questioned her as I was also furious. Jenny had nothing to say and just shrugged. Until she finally said, “well Jess is always telling us about how good you are in bed. So I was curious.” I asked Jenny, “what the fuck?! That’s your excuse!!” I replied in anger. “How the fuck can you be so calm about this! You fucking whore of a bitch! Where is Jess anyway?” Jenny replied, “At IHOP with some friends.” I started to panic, not knowing how I could explain this to Jess. I said with anger, “Your sister is going to kill us!” I figure to come clean to Jess and refused Jenny to leave so she can explain her side, if she had a reason. Jess walks in….
