when a bitch hums yo nuts

By Sticky

When during a Blowjob the giver hums to the Batman theme song whilst an erect Penis is motioning back and forth in their throat and at the same time simultaneously flicking the receiver's balls as if it were the lunchtime bell.

My genitals were on sexual fire so bad when Jamie gave me a Hum Dinger that my heart stopped. Who's Speechley fooling saying that he's not sexually experienced....the Hum Dinger he gave me told me he's done this kinda thing many times before. If I'm not copping a Hum Dinger...I'm not alive!
