My dicks length

Divya asked whats my dick lenght as i know she knows i am on smaller side. My sister brings a tape and they ask me to take off my bottom.

As i strip down my shorts and boxer and soon as my dick come in view both my sister and girlfriend start to laugh uncontrollably and it was my worst nightmare and they showing me their pinky finger it was so much humiliated.

As they calm down a little and messure my dick it was just 1.2 cm and what i don't know was my sister was recording all this in her phone. And even they made me say it pretty loud. After that they show me that she recorded my mms and i was shocked to see that.

Now they ask me to do what ever they say
