Pin-Cushion

Pin Cushioned
An orgy with a 5:1 Guy:Girl ratio. Can be done with skinny girls, but much easier with fat girls.
Martha liked having a boyfriend, but thought "hey, where's the fun in only one boyfriend?". So to compensate she got four more. One thing, one thing, one thing, one thing, one thing led to another and she was pin cushioned by the end of the night.
