In what may be a record, a passenger masturbated for “up to three hours” yesterday as he traveled on a Megabus, according to Iowa police who reported that the suspect continued pleasuring himself because he thought a female victim “was enjoying it.”

Cops were called Sunday afternoon to a bus station in Coralville, an Iowa City suburb, to meet an arriving Megabus.

According to a criminal complaint, officers were told that passenger Telly Shadell Corey, 41, “was on the bus with his penis exposed to a female passenger that was terrified.”

A subsequent investigation determined that Corey initially “played with his penis in his sweatpants.” He then “ended up exposing his penis and masturbating for up to three hours because he thought the victim was enjoying it.”

After being read his rights, Corey reportedly copped to the marathon pleasure session and told police he thought “since the victim didn’t say anything to him she was enjoying it.”

Pictured above, Corey was arrested for indecent exposure and booked into the Johnson County jail, where he is being held in lieu of $2500 bond. Corey’s rap sheet includes multiple arrests for narcotics possession.

According to the Megabus web site, the low-cost carrier promises customers that, “you will be riding in comfort and confidence. We provide affordable and reliable bus services, offering the highest level of comfort and safety. You can be assured of a great experience and overall satisfaction.”
