Amnesia
Suddenly, she hops off the bed and stands up. She takes off her top completely and covers herself with her hands. 'Wanna peek, baby? I know you do.' She laughs and goes to look through the drawers of the dresser. 'Oh! Now this hurts, you'll love this. We haven't actually used it too much, so it might not do a great job of helping you remember, but oh well!'
She walks back over with a dildo in one hand and the other hand behind her back. 'See this baby? You want this inside you, hm? Want me to fuck you? Pump it in and out till you cum for me?' You're so horny, you can't help but nod. You hurt so much, but she's right, it's turning you on like crazy. 'Haha, you just keep thinking that.'
She kneels between your legs so you can't see what she's doing for a moment, then jams the dildo inside of you. You feel full, then slowly you feel a faint tingling sensation. [Lube up the dildo with icyhot or toothpaste and put it inside of your pussy] The tingling grows into a burning and you begin to squirm.
'Haha, does it burn baby? Squirm all you want, but you're the one who said you wanted to be fucked! You should've known no pleasure comes without pain when you're with me!' [Pump the dildo in and out of you for two minute, re-apply the icyhot/toothpaste, then leave it inside you]
