"Cum for us, Erica."

It was obvious what Lisa meant, but I was too scared to move. “Cum for us, Erica,” Lisa clarified.

I felt a strong urge to take one of my hands and lower it to my bare pussy, albeit shakily. At first, my hand stood guard, covering my secret treasure, but soon enough my fingers began to move on their own, I couldn’t believe myself, I was pleasuring myself in the middle of a bus!

Trying my best not to make any sounds, I continued to tease my lips, which were beginning to get very lubricated very quickly, my other hand slipped down as well, this one pinching my very erect nipple.

If anyone turned around now, they would be watching me masturbate in the middle of the bus.
