College student Melanie is caring for her neighbour's adult baby boy when it was time to change his diapee.

His willy looked a bit big when she undid his diaper but then while she was wiping it clean it grew into a very thick, very long stiffy.

She has never seen a cock like that and with no one else expected home she grabbed to opportunity to try it in her tight young pussy.

It hurt a little bit at first then felt amazing. She had so many orgasms before she took it in her mouth again and made him do the biggest cummies for her.
