After a few days of convincing she came around and wanted it too. Over the next several weeks we sent dirty text messages filled with pictures and wha...t not. But finally, when we had the chance we met up at her house while her parents were away. Upon getting there we start drinking right away. Meanwhile she is texting her brother to find out when he is coming home from hanging out with his friends. Finally he texts her back and says “like 45mins”. Hearing that, I tell her that it isn’t that much. Suddenly I heard a girl’s voice, and down the stairs comes a normal-looking bloke, followed by a sex-queen, curvy and bosomy in a breathtaking low-cut top. I’m stunned, and can only gawp, mouth hanging open as She walks past the shelves. My gaze is fixed on Her lovely bulging big tits in that skimpy top, and despite the risks, I’m helpless, unable to do anything, apart from gasping “ohhhhh!” Then She turns Her head, raising Her eyebrows and saying loudly to Her companion – “here’s the big. It felt cold and wild as it rolled down my ass crack and forward over my tummy. I then pulled one of my tits to my face and began sucking my nipple. Hard. Emboldened, horny, and I suspect a little drunk I stopped sucking and just licked my nipple. At the same time I poured the remaining liquid in the bowl onto me, right where my tongue met my nip.I was so turned on at this point I just can't describe it. My pussy was screaming for an orgasm. I didn't touch it quite yet. Instead I reached down. Calm. Hard to Focus. Trying.” I heard in my head.Whatever was happening was becoming for longer times. It got to the point where she was there lying on me, sometimes hearing the engine noise, and the rest of the time, it was silent. The quiet times got longer, and I was able to start feeling her racing heartbeat, along with her heavy breathing. I started rubbing her bareback from her shoulders to down over her butt. Whenever I got down along her sides above her hips, she giggled. Touching below.
