It was just another over night babysitting gig. I was nearing the end of high school, and studying hard for end of year exams. I had turned 18 about a month earlier, and was bored with still being a high school girl. I was ready to get out on my own and into a dorm at school. In addition to extra studies, I was also working my butt off, trying to raise extra money so I didn't have to work during the school year.
So when a friend called and asked me to take her babysitting job at the last minute, I reluctantly said yes. I was supposed to go on a date that night, but I really wanted the money. I called up my boyfriend and told him. He was disappointed, but he understood.
I got there and it was the usual set up. Two kids, make them dinner, get them to bed. Parents wouldn't be home till late at night, so I had the guest bedroom for myself. The one weird twist was the kids grandfather. He lived with the family but didn't have it in him to care for the kids overnight. He didn't need my attention and they said he would keep to himself, so I figured fuck it.
It was pretty average. Through the night as I kept the kids busy I got a few texts from Brandon. He was bored and horny. He hadn't made plans since he thought we would be going out. I felt bad. I finally texted him and broke the big babysitter no-no rule. No boys in the house. I told him to come over and text when he arrived.
He was there in no time. The kids had been in bed over an hour and I hadn't seen grandpa hardly at all. I shushed Brandon and showed him the way to the guest bedroom.
We wasted very little time. We had been going out a few months and loved making out and fingering each other. Recently we had started blowing each other. We wanted to go further but our school taught abstinence only. Furthermore, both of our families had taught us that sex was something to be saved.
Our sex drives running overtime, we fooled around whenever we could. It was tough, though, since we barely got alone time or private space. Usually the back seat of his car had to do.
Tonight we had privacy, and even a bed. We were quickly on top of each other, making out and groping. He soon progressed to bringing his hand up under my skirt and was fingering my pussy, first through my panties and then under them. He knew exactly how I liked it and ran his fingers from my wet slit to my clit over and over, lubing it up and then fingering it roughly. I moaned into his mouth as I came, shuddering. He knew my body so well.
I barely had time to recover before he pulled me into a sitting position and stood in front of me. His hard cock was straining against his fly. I eagerly undid his belt and unbuttoned and unzipped his trousers. Pulling the waistband of his briefs down, I exposed his cock and balls. He had a nice big dick and kept his balls shaved. I ran my tongue all over the head of his cock, down the shaft, and lapped at and sucked his balls. I teased the head of his dick, racing my tongue around it slowly, then quickly, then slowly again before I inhaled his entire dick into my mouth. I sucked him enthusiastically until he was shaking. He ran his fingers through my hair and finally grabbed my head and pushed himself deep, the tip right at my throat. He groaned softly as he came, shooting hot cum straight at my throat. I swallowed as he came, not missing a drop.
