Mandy and I

Several weeks had passed since my last experience when Gary and I had a threesome with Gary's half sister Mandy when she popped round to see Gary. She hardly acknowledged me and sat talking to Gary about their mum. After a while they joined, me on the sofa and we spent the rest of the evening chilling, listening to music and a lot of drinks. It was getting late when Mandy said she had to go and I offered to walk her home. She declined but as she stood up she was clearly drunk and was having trouble standing so Gary insisted I walk her back. Mandy lived just off the High Street and her Mums house was accessed from a very narrow passageway that led behind the shops and to the back of a small park. As we walked up the passageway she was practically falling over and as I tried to hold her up she fell down until she ended up with her legs wide open and her red knickers clearly visible in the street light as her shirt rode up her backside. I stared at her knickers, they were pulled so tight I could clearly see her slit and felt my cock respond as she pushed away offers of help to get her up. There was a hand rail along the passageway but as she reached up and tried to pull herself up she instead ends up kneeling slumped against the wall. I stepped forward and again offer to help but in my efforts to haul her to her feet all that happens is she ends up with her face in my crotch and try as hard as I could I could stop my cock start to harden as her face pressed against my crotch. As if realising my cock is now against her cheek she looks up at me and starts calling me a dirty bastard. The only thing is she is so loud I'm sure half the town must have heard her so I plead ignorance and tell her to be quiet as she will wake someone up. Instead she looks up and tells me I just want her to suck my cock. I can feel the first signs of panic and try again to lift her but instead she starts laughing and reaching for my buckle, starts to try and unbuckle my jeans as the same time once again calling me a dirty bastard and telling me to get my cock out. Again I try to lift her up but as I do she opens her mouth and bites my cock through my jeans. I jump back as I feel her teeth sink into my cock but she holds on to my belt and somehow manages to release my jeans and in one violent tug both my jeans and my pants are pulled down as she grabs my cock my own lust takes over and holding the back of her head I thrust my cock into her mouth as she starts to suck me deeply. The intensity of her sucking was amazing and I soon felt my balls tighten as she deep throated my cock before licking around the head before repeating this several times until I was sure I was going to cum. Then she reached up, holds onto the rail with one hand and at the same time pulls her knickers aside and starts to finger herself and intermittently massaging her clit vigorously. The intensity of the moment is so great any thought that we can be seen, heard or in fact discovered has gone and sheer passion takes over as I feel her suck hard on my cock before biting it again. I jump back and she slurs she wants me to fuck her. I don't hesitate. I put an arm under her arm pits, lift her, spin her round so that she is bent forward supporting herself on the wall and she tells me again to fuck her as I lift her shirt, pull her knickers aside and easily enter her very wet pussy. I know I can't last and drive into her as fast and hard as I can as she starts to groan and keeps telling me to fuck her harder. I cant hold back, reach around, grab her huge round tits and explode deep into her as I hear her scream as her own orgasm takes her. For what seems like an eternity we stay fixed in this position breathing so heavily I feel like I've been running and then the reality of the situation hits me as I hear police sirens. It suddenly occurs to me that someone could have called the police and supporting her as best I can I half drag her up the remaining passageway, into the park and we half run and stumble to her front door as she fumbles for a key. She turns, kisses me on the cheek and tells me to go. I don't need any encouragement and as I leave the park by the other entrance I can see another Police car arrive and as nonchalantly as I can, I calmly walk past them as they exit the car and stand talking into the car radio. A few weeks later I saw Mandy again and she told me that she had seen the Police running down the passageway about 30 seconds after we had left. It was a close call but so intense I'm not sure I would have minded even if the Police had caught us.
