My soccer teammates told me what they did to you. They said they picked you up and carried you into the women's change room, made you strip down to your tighty-whities and kiss their feet while they spanked you. That must've been so humiliating! I convinced them to leave you alone, though. But the only way I could do it is by claiming you as my bitch. If you don't want them to keep training you like a slave, then you're going to have to convince them that you really do belong to me. That's why I invited you over - so that we could practise! First, strip for me. Say "Yes Mistress" and do it! Now kiss my feet. Hmm, I don't think kissing my feet will be enough to prove to them that you really are my bitch, though. Kiss my asshole instead. Only a submissive slave would do that! I think I should spank you to. Oh my god, did you just visibly flinch from that? LOL! You're such a wimp. Fine, I won't spank you. How about I tickle you instead? Can you handle tickling, little bitch? Now tell me that I own you while I tickle you! You make a pretty good slave, you know. I think we'll easily be able to convince the other girls that you belong to me.
