When Mark's parents went away for the weekend it was the perfect opportunity for us to spend the night over with the house to ourselves. There was a group of us lad's, all in our teens.
We arranged to get a load of alcohol and meet up at the house around 8pm. I was the last to get there and Mark, Neil, Danny, Eddie and Sean were already setting about the booze.
Danny had brought a porn film and this was playing on the TV when Mark's sister Jane and her friend Rachel walked in.
Jane and Rachel were a couple of years older than us and we had all known them for years. They were a pair of teases, often making suggestive comments and trying to belittle us with remarks about us being "little boys".
If anything the girls seemed even more buzzed than we were, and they started to provide a running commentary on the porn film. Questioning whether we had ever done anything more than watch such acts.
Jane, in particular, was taunting us all about the size of our penis's compared to those on the screen. Any defence we put up was met with the challenge to "prove it, and get it out". none of us seemed ready to take up this.
As the talk got more sexual Rachel raised the topic of the soggy biscuit game, which none of us in our naivety, had heard of. She explained that a group of boys would gather together and masturbate over a biscuit, with the last to cum having to eat the sperm strewn item.
This was a red rag to a bull to Jane and she began to squeal that we should play it. We on the other hand were not so keen, both through shyness and the thought of losing, Yuk!
The girl's though were getting more and more excited at the idea, saying our refusal was due to our "tiny cocks", this was part of the reason for my reluctance. I was not very mature for my age and I had noticed in the school showers that others were far more developed than myself.
While I had no intention of submitting to their taunts, Eddie and Danny appeared to be getting more enthusiastic about the proposition. It was then that Danny suggested a variation on the game. As we would be expected to be exposed infront of each other and the watching girls he suggested that instead of using a biscuit we masturbate over either Jane or Rachel, with the loser having to lick the sperm of their body rather than consuming a biscuit.
Neil and Sean both sided with Eddie and Danny and agreed to this scenario. I was still very nervous and Mark was also reluctant to do such a thing with his sister.
