Accept a spanking.

She calls Annie into her office and asks her to bring a chair with her, she tells you to strip down and lie across her lap. Humiliated and with no other options you take your clothes off in front of your teacher and best friend. Annie begins to giggle commenting 'Nice cock John' to add to your embarrassment although you are slightly flattered. You climb onto your teachers lap with your erect penis in between her legs which she quickly closes, trapping it in. She then begins to spank your bare ass as you yelp in pain.
'Beg me to spank you , you little bitch!' your teacher yells at you. You do as she says and repeatedly ask for the punishment and worship her and Annie. The ordeal goes on for about 20 minutes by which time your ass is unbelievably sore and your teacher stands up, letting you fall to her feet. Just when you think it's over she starts to undress revealing her black and red bra and panties trying there best to hold in her beautifully busty body. She then instructs you to get back on her lap as she once again continues to spank you, this time with both of your warm sweaty body lying across her beautiful tanned legs.
After another half an hour of excruciating pain paired with unbelievable lust she stops and says 'Okay so normally this teaches boys their lesson but by the way that you are still staring at my body and with that erect cock, you obviously haven't learned anything, so I'm going to give you a choice, you can either accept another hour of beating but we me being naked this time instead and at the end of it you can keep my bra and panties OR you can go with Annie and promise to do what ever she asks of you?'
