I was sleeping over at my friends place and we were staying in the living room. Everyone else was asleep. We where playing truth or dare. I dared her to masturbate. She said,
'What is masturbation?'
So I said,
'Ok, First take off your top.'
Her breasts are HUGE! I then said,
'Take off you pants.'
She said no way.
I told her to lay down and spread her legs wide.
'Put you hands down your pants and feel in your ***** for a lump. That's called your clit. Now rub it.'
She did and I played with her nipples.
She asked, 'what's supposed to happen?'
I said 'Just keep rubbing.'
Eventually we stopped because she just couldn't do it.
