Trinked into Wanking SeXStoRY

When I was f******n, myself and my mate had mitched off school and were hanging about in the local woods. Two girls from another school came up to us and started talking to us. They were both really pretty but a couple of years older. They asked if we wanted to see their cunts, we couldn't believe it, they said they would show us if we showed our hard cocks. Eagerly we got out our cocks, stroking them to make them even harder. The girls teased us hitching their skirts up higher till we could almost see their knickers. They then said they wanted us to wank each other and only the one who doesn't cum will get to to their cunts. We were like dogs on heat, we grabbed each others cocks and wanked furiously, then after a couple of minutes my mate shot his load all up my arm and on my school jumper, my hand had sperm between each of my fingers. When I looked up the girls were running away. Leaving my with a hard on and covered in my mates spunk.
