Anna

You wake up in bed naked next to a mutual friend from last night.. Who happens to be a futa. You first met Anna a few months ago at a party at a friends house. Ever since then you have bumped into her at other social friends and she has always seemed friendly. Last night, she was the party host. You stayed late to help clean up and were very drunk, so Anna took your keys and offered for you to stay the night. You wake up with a killer headache and very sore body. As you lay there trying to recall last night, you realize you are not in your bed and not alone. Next to you is Anna passed out asleep and obviously naked. What happened last night?
