camel wank

Also known as titty wank or tittywank. The sexual act of a female (or perhaps anyone with sizable breasts) using breasts to stimulate a penis, possibly to the point of orgasm. Derivation unknown, but may be a metaphor for a man sitting between the two large humps of a camel.

After she sucked on his penis on her knees, she wrapped her generous breasts around his penis and camel wanked him until he came on her face.
