Save Mom for later, crank one out before leaving.

After wiping your cock and musky balls on your sleeping mother's face and hair, you peel off her panties and confirm that she is still wearing the cum soaked panties from earlier this morning. You wrap the fabric around your cock and begin jerking off as you sit on the edge of their bed, all while watching porn on your father's work laptop. You hold back nothing as you grunt and moan in tandem with the video, shaking the bed with each stroke. Feeling yourself get ever so close, your left-hand jets out onto the bed to grab some part over your mother to push you over the edge and partially to brace yourself for the massive orgasm. You feel your cock explode as you grab onto something soft and round.

You have no issue giving your mom's panties a second, third, and fourth helping with each spurt of semen. With so much cum, it also spurts through the fabric, coating the computer and the floor as you sit there, gasping from the experience. You place down the laptop as you stand up, mother's cum coated panties still hanging off your cock. You make your way back over and slide the panties back on Mom, hearing another audible squelch. You look over at your father's work laptop. You feel a little bad for cumming all over it but remind yourself that he's going to become a cuck that pays you to fuck mom, so...no use crying over spilled cum when there's so so much more to spill.

You make your way out and consider adding insult to injury.
