A Tug And A Wank

"Since you want to take things a little slow, how about we watch some porn to jerk off too?" Sally suggests nonchalantly. This seems like the best suggestion to take. You're still horny after getting that great blowjob and judging by the giant erection Sally still has, she is obviously horny too.

"That sounds like a plan." You agree, at least this way you wouldn't have to worry about taking Sally's condom covered cock inside you. Reaching under the coffee table in front of the two of you, the excited centaur pulls out her laptop and brings up the screen onto the TV's wireless connection.

"What are you in the mood for?" You've never watched porn with someone else before but you didn't think it would feel this awkward. Should you suggest a video you like to pull it too or do you let Sally take the lead on this. Your palms get sweaty as you try to decide what to do next.

"I'm up for anything... How about you choose, it looks like you know what you want." You point to her veiny dong that is resting on your leg as she is sitting around you with her horse belly against your back and her legs on either side of you.

"Ooh, you're gonna regret that Love." Sally types away on her laptop while you sit patiently with your dick in your hand. She brings up a video of two horses mating. She isn't even on a porn site, it looks like something from the discovery channel or a nature documentary. "This is a good one." Your girlfriend reaches over past you and starts stroking the thick horse meat right in front of you. You look on in disgust to the images you are seeing as a brown horse is mounting a blonde filly on screen. This is a boner killer for sure as the dick you're stroking is going more than halfway limp. "Is this getting you on Stevie?" Sally asks not even bothered to move her eyes away from the TV.

"Yeah..." You half heartily lie.

"Ha, ha, Hahahahaha." Your British futa girlfriend starts laughing uncontrollably as she pauses the video. "Do you actually think I wank to this?" She looks at you with a grin from ear to ear as you realize she was punking you. "You lying wanker, I don't get off to horse shit."

"You were the one lying to me." You give her a playful push as you join her in laughing. Honestly you are just super happy you don't have to fap to animals banging.

"Oh do you like this, yeah. You actually thought I was into this. You sick puppy." She mocks you while shoving back at you. After having a good laugh, Sally goes back to her laptop. "Now here is something we can enjoy." You look towards the screen and see a girl in her twenties on her bed. She has a short pixie cut hair style with a deep red colored dye job. The hair matches the lipstick she has. You're woody grows back to full length as the girls brings out a red vibrator and starts stroking her south of the border lips with it. You get lost in a trance, tugging at your hard on to this girl masturbating on camera. Sally sees you mindlessly stroking off and gets an idea, a most devilish and devious idea. "Hey, Steven. I just had an idea of how to make this more fun."

You snap out as you remember there is another person in the room with you. Porn does tend to make you unfocused on other things around. "What, I think this is plenty fun. What were you th-thinking?" You stammer as it is hard to speak when so much blood is not pumping to your brain.

"I was just thinking we have a contest to see who lasts the longest." You knew Sally can get competitive but to compete over jerking off, this is intriguing.

"You had my curiosity, now you have my attention. Go on."

"We masturbate and who ever cums first loses."

"What does the winner get?"

"The loser has to let the winner penetrate them." It would be great to penetrate the girl you've been dating for so long. Plus you already came, it shouldn't be hard to out last Sally.

"Okay, it's a deal."

"Great." Sally shakes your hand then grabs onto your dick and starts pumping.

"Hey, what are you doing?"

"Trying to make you cum. This game only works if you jerk off the competition to make sure they aren't just stroking it too slow." You didn't think about that. You try slowing down your breath but getting a handjob is getting your heart to beat faster. You look over to your left and regretfully grab onto Sally's fat dick. "MMmmmmmm." Sally moans which sounds like a neighing. You pump your arms up and down her long shaft, feeling the long mass you definitely do not want that to penetrate your ass. The latex condom over it gives you an odd sensation, like you're stroking a water balloon filled with something a lot thicker than water. You look back onto the screen to see the porn actress inserting her toy in and out of her. You don't know how long you can keep this up while Sally's handjob is just as effective as her blowjob. "You're hands feel so good on my dick, Steven." Sally moans.

"You're too." Its actually feeling a little rougher do to the friction she has, you hope she doesn't chafe your penis or give it an Indian burn. At least the pain is helping you stave off climaxing.

On the screen, the porn star put her vibrator away and reaches into her box for a new toy. Both you and your horny centaur girl's eyes light up when she brings in a big, black, dildo shaped like a horse cock. "Yes, Yes, Yes." Sally mutters as her hand slows down and grips you hard as she goes into a nice up down motion. The girl on the screen puts the base of the toy on the ground and positions herself above it, letting the squishy head rub against her soaked lips. The frills on the head insert themselves into her pink cavern and she lets the phallic object stretch her labia apart. "Look at her go. I bet she plays with that thing every night." Sally's commentary only adds to your erection, you wish she would shut up but you are too focused trying to outlast her to say anything. The girl bends down, letting the black bully cock enter her inch by inch, moaning as she stretches herself out. "Yeah, stretch it. Take that fucking horse stick." You notice that the centaur isn't even noticing you anymore. You know that if you don't take the initiative than you're gonna lose. You start focusing more on her dick, squeezing harder on the shaft and feeling the veins through your fingers. You start digging your fingers into her meat as you stroke it, going down to her balls and up to her sensitive head. Sally feels this as she brings one hand to play with your sack while the other works your length. The actress on the screen screams as she gets closer to the fake pool ball sized testicles on her giant toy. She starts humping the toy, moving her hips up and down, faster and faster until her knees give out and she falls back onto the floor.

"AAAAAAAAAAARRRRRRRRRRRRRRGGGGGGGGGGGGGHHHHHHHHHHHHHHH"

She then slides the toy out as she cums, showing off the gaping hole left behind in her destroyed pussy. "That's so fucking hot. I just want to get your asshole as stretched out as her twat." Sally moans as the two of you picture that image. It fills you with terror but also another feeling. You feel your balls aching and you're not sure if you can hold it in this time.
