While walking home from school I spot the boy I've been seeing, we get chatting and I invite him to a party I'm having at the weekend, such a shame he cant come as I had a little surprise planned for him for his birthday. He teases me trying to get me to tell him what the surprise is, so I decide to show him instead. We hide behind a tree and I get his cock out and start sucking it, then lean against the tree so he can fuck me from behind. We fuck in a few positions before he shoots his load over my tits.
