With all this flirting with Lance and Newton, it was easy to forget that Mani and Pero are still a couple. Those twins are very playful while they have hot mousecest sex. giggling and cuddling affectionately, treating it more like a fun game...with dicks. They've been fucking each other for so long, it become weird when they DON'T screw around. Mani and Pero aren't shy about fucking in front of their friends either, especially Lance and Newton. Orgasming in your twin brother's rump isn't THAT much a big deal, right?
