RumTumTugger

A contraceptive act performed during missionary style sex whereby the male partner removes his erect member from his female counterpart's vagina before ejaculation, thus allowing the female to firmly grab the male's prick-shaft and stroke him to completion spraying seminal lust ropes upon her abdomen.

"Ernie came over last night and we fucked, but we don't like babies. He pulled out and I gave him a RumTumTugger so he wouldn't fill me with worry."
