It was a lovely warm late spring/early summer day, a few years ago, when I was in my late teens. My boyfriend Rob, in his 20s, came round to call. He turned up in a nice white t-shirt which showed his muscles and a pair of snug fitting jeans. Rob asked if I fancied a walk in the woods. Of course, I said yes. Before we go he said why don\'t you take your bra off, you\'ll be much more comfortable in this heat. OK I said, and ran up stairs. I could see my nipples quite clearly through the cotton of my peasant top, in the mirror. I wasn\'t sure about going out like this, but Rob assured me I looked great. As we walked down the road and past the shops I was sure people were looking at my boobs bobbing about and at my nipples sensitised by the unfamiliar feel of the cotton rubbing against them, poking out. Rob said not to be silly and the reason people were looking, especially the men, was that my tits looked so good. We were soon walking through the park, not many people about during the day, but the sun was shining down and it was lovely and warm. Of course, it was a little cooler in the wood, we walked until we came to a small clearing where a large tree trunk lay on the ground. Rob suggested we sit here, with our legs either side of the trunk, he behind me, so we faced the view of the corn field, and the foot path that runs through it. It was a lovely spot, with the beauty of nature all around us. As I leaned back into Rob, he pushed my strawberry blond hair to one side and nuzzled my neck, whispering sweet nothings in my ear, as he pulled down my peasant top, exposing my 36E breasts to the elements. Gasping I tried to cover them up, but Rob pleaded with me to let him, so I gave in, and watched as he cupped my breasts in his hands and played with my already sensitive and swollen nipples. Just then I heard a man calling his dog, and looked up to see an older man (old enough to be my father) walking along the foot path, I tried to cover myself up, but Rob held my arms down, and said \"let him have a look, you\'ve nothing to be ashamed of\", so I tried to relax and Rob loosened his hold. \"Cor, lovely pair of tits on \'er, mate\" shouted the man. I felt myself going bright red. Rob just shouted \"your right mate\". Than man walked on, looking over his shoulder until we were out of his view. Rob\'s hand moved to my open legs, positioned either side of the large tree trunk, and put his hand up my skirt, his fingers reaching inside my knickers to feel my delicate folds, gently at first, then he dips in one then two fingers inside me, making me gasp. He pushes his fingers back and forth, in and out, rubbing my swollen clit, until I am a quivering wreak and come into his hand. \"Good girl\" he says. He gives me a moment, then s his turn. I thought he meant he wanted a blow job, but no, he wants to do \"it\" doggy style. I\'ve never done it before, its only a few weeks since I first had sex with him, and I\'d never done it with anyone else before ... eager to please, I am nervous, what if I don\'t do it right, what if someone sees us ... He says not to worry, he tells me to take my now wet knickers off, stand with my legs either side of the trunk, and lean forward with my hands on the trunk to support me. He lifts up my skirt, exposing my bottom to the air, and holds onto my hips before pushing his long hard penis fully, deeply into my tight inexperienced vagina. I can\'t help but yell out. \"Oh, that\'s a good girl\", says Rob, as he draws out and thrusts in again. My god it feels so good, I love having my boy inside me ... He is pumping me hard now, I get the sensation somebody is watching us, but I can\'t see anyone ... Rob continues to pump into me until he comes filling me with his spunk. Then he says I am to stay where I am. He wants me to lick him clean. So he comes round to the front of me, blocking my view of the field, and offers me his spent penis to lick, which of course I do willingly, tasting his cum and mine. His hands are either side of my head, fingers through my hair, smoothing it back so he can get a better view of my mouth on his cock, offering encouraging words. I have the sensation that there is someone behind me, I realise my bottom is still exposed, in invitation, and try to pull away, Rob holds onto my shoulders, as I feel another pair of hands on my hips and the tip of another penis at the entrance to my vagina - \"you got hold of her\" says a strangers voice, \"yes\" says Rob, before I am impaled upon a penis much larger than my Robs (his one is long and thin, the one inside me now is long and wide), I cry out and throw my head back with the pain and pleasure of having such a large cock inside me, both men laugh and I look up at Rob, he is looking down and smiling - \"shh, its alright\" he says to reassure me and strokes my hair - \"lovely tight cunt\" says the other man, before pulling out and re-entering me, he does this a few times. Never giving me enough time to stretch and accommodate him fully, so that I gasp each time. Now that the stranger has me in his grip and is pumping me hard, Rob moves to the side, presumably to get a better view of me being fucked by another man, as he moves a couple come into my view, they are walking up the path they look over, and I can see them smile at the view of me being fucked, my tits out on show, I feel so degraded but excited too, the next thing I know I am crying out with another orgasm and feel myself shaking and coming. The couple continue on their way, looking over their shoulders, the stranger continues to bang into me until he too fills me with his cum. Then he pulls out, slaps my bottom and says \"that was lovely\" as I collapse into Rob, to Rob he says \"your training her well mate, and he\'ll see us next time\". I can see that all this has excited Rob as he now has another large hard on. As I\'m now sitting back on the trunk, two lots of cum trickling down my legs, Rob stands before me, and offers his cock to my mouth. I give him a blow job, licking and sucking him, until he is fucking my mouth, shooting his load to the back of my throat for me to swallow down. When we\'ve righted our clothes, and I\'ve wiped my face on my hands, he asks if I\'ve had a nice time, and I say yes and ask him if he knew the other man, he just touches the side of his nose and says \"that would be telling\". He holds my hand and leads me back through the park and home. I am left wondering where and when the \"next time\" will be.
