Make a quick exit. You're not cheating on your girlfriend with her sister!

"No way can anything good come of this!" you think to yourself, as you inch away from your girlfriend's sister. "Hey Nicky, what you do in your room is your business. You don't have to tell me anything about it. Like I said, I'm sorry we woke you up. I'll try to make sure Tia and I are more considerate next time.". Gulping down the rest of your coffee, you quickly retreat to the sink and rinse out your mug, then say a quick goodbye, unable to get yourself out of there fast enough.

During your walk back to your place, you try to wrap your head around what just happened. Did your girlfriend's hot, little sister really just throw herself at you? And did you really give up the chance to fuck her?

Letting yourself into your house, you head to your room, get undressed, then hop on the shower, still debating what you did. One part of you is proud of yourself. Proud that you're showing some maturity and being faithful to the girl you love. The other part is openly mocking you, telling you what a pussy you are and saying you missed out on the opportunity of a lifetime.

These thoughts continue to swirl in your head as you get dressed, drive to work, then try to get through your day. Someone must be testing your fortitude today, because your final two clients of the day are both incredibly hot and you struggle to keep your erection under control.

Day finally finished, you climb back in your car and start your drive home, so engrossed in your thoughts, you almost don't hear you phone ringing. Glancing over, you look to see who's calling.
