Spicy Speedbag 

When you are having anal (doggy style) with a girl you secretly dip your nuts in medium-hot salsa and proceed to fuck. The now spicy testicles hit the vagina repeatedly and propel the salsa in and around the vagina.

Girl: You wouldn't believe Chris last night he gave me a spicy Speedbag. I douched twice and it still burned!

Humdinger Speedbag

Cunalingus delivered with an extremely high frequency of tongue movement in a semi-eliptical progression. Varying pressure must be applied to execute properly.
