She resisted a little, but as Jon pulled his sister's panties to the side all the 15 year old goth could do was moan like a slut as Jon rubbed his engorged member against her soaking slit.

The goth girl screamed in pain but moaned in pleasure rocking on her brother's cock as he started to move slowly but surely.
"Oh Jon... this is so wrong," she moaned as Jon's parents looked up from their own making a slightly disapproving look, that said Jon's mom also seemed to have curiosity while Jon started to thrust with regularity, he wanted to make his sister cum, then he had some wishes to make.
