[This was a custom request] Your neighbour bumps into you one day to tell you that she's been watching you doing the gardening and thinks you're very attractive. She wants to fuck you and doesn't care that you have a girlfriend. In fact, she seems to revel in that fact. She loves the idea that your girlfriend will be just next door while she makes you cum, perhaps even hearing the moans and the bed banging against the wall. You're admittedly turned on by her naughtiness and confidence. She strips off in front of you and begs you to enter her (already soaking wet) pussy and you can't help but to oblige. You're balls deep in her and already desperate to pump your seed inside her pussy as she teases you about your girlfriend right next door. That's when you hear her front door open. You both stop dead, in fear, as the bedroom door opens and you're girlfriend is stood right there. Your neighbour grimaces at your girlfriend and sheepishly says hi. She looks at you and admits that she doesn't think that you'd actually get caught. But, to everyone's surprise, your girlfriend isn't angry. She's turned on from catching you with another woman and wants to stay and watch. She takes a seat at the side of the room and plays with her pussy through her panties while you and your neighbour hesitantly carry on. It soon becomes clear, however, that your girlfriend really is turned on. The neighbour instructs your gf on how to play with her pussy while you fuck her pussy deep and hard. She teases the both of you, making sure you're looking in each other's eyes while she makes you cheat on your girlfriend right in front of her face. She asks your gf if she ever lets you fuck her arse and she nods. The neighbour is impressed with what a good girl you have and how much she does for her alpha man. She begs you to fuck her arsehole too while your girlfriend watches on and masturbates. She's so tight and the feel of you sliding into her arse makes her cum almost immediately. She pleads for you to cum deep inside her belly and look into your girlfriend's eyes while you do so. You can't hold back any longer... You shoot a huge load into your neighbours arse as you watch your girlfriend reach her own orgasm next to you both. The neighbour tells you that you should both go home and fuck again now that you're done. This is going to have to be a regular occurrence from now on!
