"Thanks so much for helping me practice. Now we're both tired, so I just want to get some sleep. Tomorrow will be a *hard* day for you, since you'll be seeing all those beautiful women that are the guests here, so you'd better be well rested!"
You nod, and are embarrassed to feel your cock stiffening that the sight of Sandy and the thought of all the beautiful women you may see tomorrow.
