Ask for a full orgasm

As her laughter dies down, you notice your cock is still hard and the need to cum is even greater than it was before your ruined orgasm. You try to move your hands down to rub your cock, but find they still won't move from above your head.

"Please let me have a full orgasm" you beg her as you continue to struggle against your invisible restraints.

"You've already had a full orgasm. Don't you remember earlier when you came all over my hand?" She says with a smirk as she starts gently caressing the head of your cock. The slight stimulation causes your cock to start throbbing driving the need to cum even more desperately.

As you release a moan, she says "I've already recast the spell to prevent you from cumming again. We wouldn't want you to have another accident. So I can at least release your bonds now." She gets up and releases her magical hold on you. As you feel the restraints disappear, you then sit up and rub your wrists that feel sore from all your struggling.

"But I think that's enough fun for one night." She says. "You've made quite a big mess, and someone's going to have to clean this up." She gestures to the cum that's now dripping down your balls onto the floor. "I'll make a deal with you. If you lick up your cum, I'll remove the magical orgasm block. It would be fun to see you licking it all up." With a mischievous grin, she says "Or I can magically clean all this up, and you'll just have to wait till tomorrow after classes before I'll let you cum."

"What will it be?" she asks
