A sexual position that produces almost no pleasure for either of the two participants. A male must insert his testicles (both are mandatory) into the females anal cavity while she is on all fours. Thusly his erect penis will protrude from her cheeks creating the unicorns horn. The man can then spread his arms, or "wings" outwards placing the finishing touches on the flying unicorn.
Kevin elegantly spread his wings atop his glistening steed of a unicorn, who was quite the hot little number, creating the perfect Flying Unicorn.
