They eventually came down from the balcony hand in hand and came up to me. Andi introduced me to her friend. All I could do was grunt a sullen hello. She told me that they wanted to go home. The three of us left the night club and got in the car for the drive back home. I drove, they got in the backseat. We were barely out of the car park before they were all over each other again. It was dark driving along that highway that night. I couldn't make out too much for the most part, but it didn't take long before I heard her announcing that she was coming. A little bit of a giggle, then the sound of a zipper being pulled down. Andi positioned herself on all fours on the backseat such that her gorgeous bum was in between the two front seats and just inches to the side of my head. The next thing I heard was her slurping and sucking on this guys cock. I could smell her pussy, If I turned my head a little bit more I probably could have tasted it, I didn't want to crash. Every time we went under a street light I turned my head to drink in the sight and aroma of her drenched cunt and blonde whiskers barely being covered by her sticky panties. For the second time that night I came in my pants. The sucking went on for almost an hour
Just as we were pulling into our driveway I heard the Stud groan and unload into my little Andi's sweet mouth. I could hear her gulp down all his come. We all got out and went into the kitchen. I tried in vain to hide the wet patch in my pants while they both got a drink of water and proceeded up to Andi's bedroom. The door closed and I could see that the light had been turned on. I don't know what possessed me but I quietly slipped outside. I couldn't believe my luck, she hadn't closed the curtains to her room, and the window was half open. I could see and hear everything.
As I peered in I could see my little honey on her back with her boots up in the air. She was still fully clothed but he was naked. He had his face buried into Andi's snatch and was doing a stellar job of eating her pussy. She was moaning and thrusting as she used to do with me. After a while the Stud and Andi got into a sixty nine position with her on top. That's when I got my first good look at his cock. It was massive. Easily twice as big as mine. She swallowed as much of it as she could while he pulled her dripping wet cunt apart and sucked on her clit. This was way better than the time I watched her in the kitchen. Needless to say my pants were around my ankles and I was going for it as much as them.
She had an earth shattering loud orgasm from all his licking. I could see her puckered asshole twitching as she came. She fell off him exhausted on the bed. The Stud however wasn't finished. He promptly positioned himself on top of my girlfriend, spread her legs, and slid all the way into her with one thrust. He fucked her with that massive cock for all he was worth, she was moaning so loudly that it would have woken the neighbors if we didn't live on a farm. She came again and again, there was a big wet patch on the sheets from her drenched and stretched pussy. They changed positions many times. She would often position herself with her creamy asshole and pussy pointing directly at the window. She must have known I was out there. I was so turned on by watching this that I too came many times, I squirted load after load on her bedroom window without becoming flaccid even for a second. The end finally came when he had rolled her over on to her back with her pussy looking me right in the eye, he had slowed down to more sensual and deliberate strokes of that massive dick. Just as he was about to come he pulled out of her and grabbed his cock, shooting stream after stream of thick white come into her stretched open pussy. I couldn't believe my eyes, it was like the best porno movie I'd ever seen. Not wanting to get busted I quietly slipped back inside, into my bedroom.
About ten minutes later I heard Andi's bedroom light turn off and her door open. I was lying in my bed pretending to be asleep. My door quietly opened and Andi crept in. She wispered in my ear, "I forgot to give you your birthday present." With that she dropped her sticky wet panties on my bedside table and said "I know how you like these." She pulled back my sheets to expose my naked body and raging hard on. Without a word or any hesitation she sat down onto my cock. She felt so incredible, so wet, so open, so soft. I came again after about ten of the most incredible strokes of her pussy I'd ever felt. She got up and left.
She spent the rest of that night and the weekend fucking her stud. I got to listen but they closed the curtains, so no more watching. I did however have my Birthday present to cherish.
