2T4U/Jack/Fucking Melony/Do as she commands
You grin in absolute glee as you force your member home into your younger sister's 14 year old virgin hole, tearing away her virginity as you get your first sex not from your girlfriend but from your sibling. The weight of it all hits you at once. Not only are you cheating on Brittany, but you are also fucking your sister. This is incest. This is so twisted and dirty and wrong, and it is just what you need to get you salivating.
"OH! Oh Jack!" Melony cries out as you bottom out against her cervix, about an inch and a half of your cock still outside of her developing pussy. "Oh, that feels so good!" Her shoulders drop as she lies back against the bed as though she is now having an itch scratched that she just couldn't relieve. She smiles up at you and begins grinding her hips up against you again. "Don't stop now, keep going." She insists.
