"John, pay attention," Mrs. Kahili, my calculus teacher admonished me.
I snapped out of my gaze and redirected my gaze to the problem she was demonstrating on the board, despite how much I had enjoyed my view of Abby Kentdale's tits. My eyes continued to wander over again and again until the bell finally rang, signaling the end of the period.
As I walked out of the classroom, Abby appeared beside me. Abby was a senior, like myself, and lived down the street from me. She had large, bulging breasts that more than filled out her petite figure. Her dark, wavy hair settled around her shoulders, and the thin, skin-tight pants she was wearing did nothing to hide her round, supple ass.
"Hey, can you give me a ride home today?" she asked.
"Well, what's in it for me," I teased back.
"Oh, come on, we're neighbors, you drive right by my house on your way home," she complained. Much to her displeasure, I had refused to give her rides in the past.
"All right, meet me out front after school, but don't let me forget" I agreed.
"Thanks," she said, and turned to go to her next class.
As the bell finally rang indicating the end of the school day, I left my last period class and began walking out to the parking lot when I heard Abby calling behind me, "Wait up!"
Having forgotten I had promised her a ride, I turned and waited for her to catch up, enjoying the view of her tits attempting to free themselves from her shirt as she ran toward me.
"Hey, how's it going?" I asked.
"Alright...seems like you forgot about me back there," she replied, adjusting her shirt so it did a more adequate job of covering her tits, while still showing an impressive amount of cleavage for an 18 year old.
"Well I did warn you," I reminded her.
"I don't understand how you could forget to give me a ride. We talked about it like an hour ago."
"I'm sorry, but it's not a big deal... you reminded me," I laughed.
We arrived at my Honda and jumped in. I started the car, and eased the clutch out as I pulled out of the spot.
I looked over and noticed Abby's tits were barely contained by her top. I shifted my legs to try to hide my rising erection, but failed miserably. I tried to avoid looking, and hoped she didn't notice my wandering eyes or bulging crotch. It didn't seem like she did, and we carried on casual conversation all the way back to her house.
"Hey, John, do you wanna help me study for the calc test for a little while? There's a couple things I don't understand," Abby told me as I pulled into her driveway.
"Yeah, I'll come over in like half an hour. I've gotta cash my paycheck at the bank," I told her.
She smiled at me as she climbed out of the car and stepped into the garage as I left her house.
