“Okay everyone back on the bus” shouted Mr. Brady, the teacher in charge of the class trip.

We all filed onto the greyhound, tired from running around the paintball course for several hours and Emma and I tried for a different reason also. It was dark by the time everyone was finally going to their seats and we started to leave. As Emma walked by me towards her seat a bit farther back, I grabbed her hand and pulled her to sit in the seat next to me. She started to say something but I silenced her with a look and she closed her mouth.

It was a good two and a half hour drive back to our hotel and with the dark quiet of the bus and the sun just slipping under the horizon, most of my other classmates began to fall asleep. Emma fidgeted beside me, obviously a bit nervous about sitting next to me but I remained composed and silent. About an hour into the trip when I felt that just about everyone was asleep, I reached over to Emma’s sleeping form and bent her over onto my lap with her head and torso facing towards me. She looked up at me wide eyed as I pulled my cock out through the hole in my jeans and pointed it at her mouth. She looked around at the sleeping forms of the other students, terrified of getting caught and shook her head mouthing the word ‘no’. I smiled and pulled the collar of her t-shirt and bra down over her breasts, letting her huge tits pop out into my lap. I placed my hand on the back of her head and pushed her mouth onto my hard dick.

She put up very little resistance for fear of someone waking up and seeing her blowing someone on the bus.
