For my 19th birthday, I got a vibrating butt plug to wear during sex and it is amazing!
Last night I used it for the first time when I rode my boyfriends cock. I rocked my hips back and forth while he sucked on my tits. He said he could even feel the vibration a bit while inside of me. The vibration combined with his cock and sucking on my tits was so amazing that I orgasmed before my boyfriend even did. I ended up just letting him fuck my tits and cum on my face because I finished before he did.
