Simone, your sister

You open the door to Simone, your sister, who's back from basketball.

"Hey, I was able to get away early. Yvete tripped and hit her head and had to go to hospital. I'll explain over dinner." She babbled.

You could feel your dad lightly fucking himself, slowly rocking on the sausage up his ass. You make your way back to where you were before on the stairs. You watch your dad lightly rocking himself on his chair.

"As I was saying, Yvete went to hospital with a head injury, but I think I still made the team." Simone recounted.

While she talked about basketball, you could see your dad holding back moans, rocking on the chair with more vigour. You suppressed your moans as well, holding your mouth shut. Your dad began to pick up the pace, not-very-discreetly bouncing on your dick, making faces in an attempt to shut off any vocal pleasure. Luckily, Simone was too into her own story to notice. You could also see now that your dad was wanking along to his fucking, full on riding your cock now. He got faster and faster, your breath getting raspier and raspier, before you saw him cumming all over the underside of the table.

"FUCK!" He screamed, his orgasm still riding.

"Excuse me?" Simone asked, surprised by such blatant swearing.

"Um, I bit my tongue." He lied.

Before you could dwell over the lame and familiar excuse, you were cumming too. You shot far up your dads asshole, as he lightly moaned at the flooding of his hole. When you finished, you pulled the ring off, and instantly saw the change in your dad's posture, with the realisation dawning on him of what just happened.

"Um, can you take my plate up for me?" He asked his daughter, aware of the smell and mess around him.

"Sure." She smiled, before scrunching up her nose. "You really need a shower dad."
