Boston Butterfly

When a man places his anus upon a frothy trollops vagina lips (preferably long meaty hangers getting blown into by a prolapsed anus). He then proceeds to blast ass into her baby tube. The meaty lips proceed to flap like a happy butterfly nectar sucker.

I just gave Alisa the best Boston Butterfly ever! Her lips were flapping like a wounded monarch!

Boston Butterfly

When a girl is full spready, man comes in with swift uppercut to the meat flaps.

But have you ever hit her with the Boston Butterfly?
