A Blowsi is a sexual encounter in which one female performs oral sex on two men. She rotates back and forth from one guy to the other, essentially giving two BLOwjobs SImultaneously (BLOWSI). It is a sexual art that only few women can master.
That girl Ashley is terrific at performing a Blowsi, she made Michael and Christopher cum in a matter of two minutes.
