Becoming a Sissy - My aunt my Mistress II

After a few minutes that man came in the back and sited next to us and said "2 beautiful girls like you at this hour, that may be not really safe", he smiled a little when said girls, watching at me, and my aunt noticed that right away because she replied "So you saw her little cock?" Then she mumbled something to his ear and the man shook his head approving, giving her some money. She then tuned to me and said "Emma this man gave us 25 bucks to see you jerking off" I almost chocked hearing that and immediately said almost screaming “WHAT ?!", my aunt cover my mouth and said me to lower my voice, so I did it, continuing almost whispering "I am not doing that"
Marie:"Well, he already gave us the money, so you have to do it, or you prefer to let everyone find out your little secret?”
Emma:"I don’t know... I can't d..." couldn't finish because she raised my skirt and she started jerking me right there. I wanted to stop her but instead my dick got rock hard and i was just stunned by everything that was happening. She then said "Keep going, I’m not gonna give you a handjob". I did as she said, don’t really know why, I kind of liked it somehow. I didn't even notice that the man started jerking as well. I couldn't back now so I just kept going, trying to ignore him. After about 10 minutes my aunt slapped my hand and started jerking me hard and said to me that is time to cum. She didn't had to say because once she grabbed my dick and started to wank me I couldn't hold it in anyway, so I just cum there in the bus while a man was watching me. I felt my brain melting after I ejaculated and didn't really heard what my aunt said but then saw her other hand full of my cum and then actually comprehended what she was saying
Marie "Come on open your mount and swallow this". She could see my disapproving on my face so she grabbed my balls really hard so I was forced to open my mouth wanting to scream, but she instantly put her hand full of cum in my mouth and said “Don’t you dare spit it, swallow it all or the other passenger gonna find out".
