This sounds like a stupid question.

What is the difference between DSL (Dick Sucking Lips) and a BBBJ?

Aren't they the same service?

Sounds like you're saying that a car, and driving are the same.  One is the vessel; the other is the action.

DSL just means that a girl has sexyy lips, that look like theyre meant to suck dick. So, the DS is an adjective used to describe the lips on a girl.

BBBJ means bare back blow job. Which refers to the service that she gives.
