A nearby empty room

Before she stopped stuttering, you grabbed Tawny's hand and led her out of the room. You then led her to another close one that was empty. Using your powers, you summoned a bed into the room. Tawny looked at it for a second before you pushed her onto it and made her clothes disappear. She still looked flustered as you also made your clothes disappear and aimed your erect dick at her ass.

"I'm sorry I completely forgot to offer anal sex to you, John. Still, this doesn’t mean anything!", she said quickly while you started to slightly lay with her breasts before starting to push in. This quickly shut her up, as you used your powers to give her overwhelming amounts of pleasure. She was unable to contain her moans as you started to thrust into her tight ass.

You were annoyed at yourself for not doing this sooner, but reason that its better you actually did it at some point. You kept fucking Tawny for a good long while, enjoying the fact that the fun was just starting. She came many times, each time moaning louder, and occasionally screaming your name in her blissful pleasure. You briefly pondered what to do to humiliate Madison more during the ceremony, and came up with a great idea, a new "rule" of traditional weddings that the guests would see as what it really was.

You were so focused on thinking new ideas you didn't notice your buildup, and were distracted from your though process by the feeling of being about to cum. You manage one last thrust before filling Tawny's ass with your cum. After this, you pulled out and your cum began to come out as she huffed, exhausted, on the bed. She then got u a bit to look at you. There was a lustful glint in her eye, but it quickly disappears.

"Just for the record, John, I'm still with my boyfriend and have no interest in you", she tells you, and you laugh inwardly before controlling her.

"Tawny, we both know you have a massive secret crush on me. You'll call your boyfriend and dump him, telling him you prefer me over him. Also, go get prepared, the ceremony is soon to begin", you tell her, and she nods, once again flustered over her "crush" on you.

After she is gone, you get your clothes back and wonder what to do. There still is some time before the ceremony.
