Fuck Buddies 

There are different views on fuck buddies. It sounds bad but there is alot more to it! Usually involves the other two liking each other just knowing they cant work. As in relationships everyone acts different. Sp they just play around with each other and fun with their time.

Hey are you and him going out i mean you to are all over each other!
No, we just like fuck buddies! We just have fun together!

Insatiable Birdie 

A sex act performed by fucking a man in the ass in missionary position while leaning over and blowing him at the same time. It can be performed by either another man or a woman with a strap-on (see Pegging).

The act is named for its similarity to the motions made by the toy heat engines named drinking birds, insatiable birdies, or dipping birds.

Getting fucked in the ass with a strapon is great by itself, but the Insatiable Birdie is MIND BLOWING!
