Yes

You stop time and take your clothes off. You stand up and put them on your seat.
You walk over to a short girl with blonde hair. You take off her pants and underwear and set the now bottomless girl on your lap. You cover your dick in lotion brought for this purpose and slam it in her tight pussy. You thrust hard and deep and cum into her womb.
Done with this girl, you strip the bottom halves of two redheads and fuck them, alternating between the two pussies. You shoot spirts of cum deep into both girls and put them down. You fuck all the other girls on the bus, filling their hot, young wombs with cum every time.
After you are done, you redress the girls, but leave your cum in their vaginas as a surprise. You also put them back in their seats. Even after fucking all those teens, your dick is still hard. You sit down and start time. When the bus gets to school, you see your sperm running down the girls' legs, but no one else notices.
