I'm a college student now, and I've got my first girlfriend, so I'm enjoying my days to the fullest. One day, she decides to come back to her parents' house for a few days. I feel a little lonely, but there's nothing I can do about it. I'm thinking about how to spend the night alone, when I get home and find her friend standing at the front door, holding a convenience store bag full of alcohol and snacks. For some reason, I'm drinking with my girlfriend at home, even though she's not there! Isn't this a bad idea? The girls continue to drink at a rapid pace, thinking about it. Then, I get a call from my girlfriend, which leaves me flustered. I just want to get this party over without anything happening! But then, the girls suddenly decide to stay the night!? Late at night, their friends suddenly approach me. But I refuse, saying I have a girlfriend. But then they make another advances in the middle of the night, and I'm defeated... We end up having sex... And there's no stopping! We end up having a threesome until morning. I think they'll go home, but the girls don't... In the end, we keep doing it for three days and three nights! I was overwhelmed with guilt towards her, but I did it anyway... I'll never be able to experience such exciting sex with her again...
