Your Younger Brother

You try to make out his feature through the opened door and you notice that he's wearing glasses, there is only one person who wears glasses in the whole family and that is Justin, your younger brother.

You pretended that you didn't notice him and continued to do what you were doing since you were really enjoying it, you continue to finger your tight pussy and slip you finger deeper, still afraid that it'll punch a hole in your hymen, you made sure it didn't went in too deep and then you started to piston your finger in and out of your pussy.

The feeling was ecstatic, you moaned and moaned, with the corner of your eyes you took a glance at the door, to your surprise you can see that Justin is jerking off, apparently enjoying the show.

You can see his cock through the crack, and it was quite big actually, you never would've thought that your nerdy younger brother would have such a large penis, seeing how big his penis is kinda turns you on more.

Seeing how hard your brother was jerking off made you really hot and bothered, and you picked up the pace and finger your pussy faster, but after a while you have this feeling of discontent.

You glanced at his cock again and realized why, you want to replace your finger with that cock.

You are really really bothered by this since he is your younger brother, but yet you are really really horny and you are very curious as how a cock would feel inside you, if a finger can already make you feel this good, then a cock would feel 10 times better.
