JULY 15--While out jet skiing Sunday afternoon, a married couple got into an argument that turned violent because the woman saw her husband and another male “involved in a sex act together,” according to investigators.

The confrontation between Michael Doster, 49, and his spouse of two years resulted in Doster’s arrest for domestic battery. He was released from a Florida jail today after posting $5000 bond on the misdemeanor count.

As detailed in a Manatee County Sheriff’s Office report, Doster and his wife Pamela, 45, were on a Sea-Doo jet ski near the Passage Key sandbar at the mouth of Tampa Bay when they began quarreling. Pamela, a deputy noted, brought up the fact that she “saw the defendant and another unknown male involved in a sex act together.”

While not specifying when or where this alleged sex act occurred, the cop noted that Pamela reported it involved “giving each other a blow job.”

Doster, who was driving the Sea-Doo, allegedly yanked his wife off the jet ski several times, according to the report. “During the last time she was pulled off she hit her head against the side of the jet ski” and refused to get back on the watercraft. Instead, she repaired to the sandbar “and refused to answer his call outs.”

When Doster could not locate his wife, he called 911. Pamela, naked except for a life jacket, was subsequently found on the sandbar and transported to safety by rescue workers. A deputy noted that she had a “bruise/bump” on her head, a bruise on her biceps, and a “large swollen area to her left hip area.” She was transported to a local hospital for treatment.

Both Doster and his wife were intoxicated, a deputy reported. (2 pages)
