Yes

To be fair, you can't see much of the actual penetration, because you're looking at your son from behind, but still, the sight is shocking, and you find that you can't look away.

Slow thrusts soon become rapid stabs, and the most devastating part of it is watching your daughter's feet twisting and turning and her toes scrunching and unscrunching as she presumably desperately tries to escape this sudden vaginal ****.

But she isn't going anywhere. Even as your son's pelvis bashes up against your daughter's plump buttocks over and over, no part of her body budges an inch away from him. She's completely and utterly stuck there.

Now if there's one thing that's relatively reliable about a 19 year old guy who hasn't orgasmed in a month, it's that he's not going to last long when allowed to fuck a pussy as hard and fast as he can. So it's no surprise to anyone that it's under a minute later that both brothers are quietly grunting and filling their condoms with a large amount of spunk.

Yes indeed, when the guy from the blue team removes his still rock hard intruder from his sister's snatch, you can tell by how full the tip of the condom is that he has been saving up his loads too. This other family presumably received the same advice as you all did, and were similarly diligent at abstaining from sex and self-pleasure.

You watch, cringing, as Thomas and this other lad carefully remove the condoms, and wrap the open end around their siblings' toe, before tying a knot. The girls, to their credit, don't flail around or resist. Perhaps they are aware that these condoms will help them in the next game, whatever that may be.

The audience above are back to cackling and jeering. This is a pretty degrading thing to have to do, after all, and they're not going to let Thomas forget it.

When it's done, the young men retreat back to their teams. You look over at blue team and see to your amazement and shock that another one of them has already got his kit off and a blue condom on his erect dick, and his heading for his sister. Shit! Why didn't you guys think of that?!

...And then you turn to your own team, and see that in fact Finch has been way head of you. While your eyes were fixated on the condom-tying occurring in front of you, he was being proactive, and, well, making best use of the time, and of his massive erection.

Who knew that both your sons had such large cocks!

...That thought makes you feel even more pity for what your daughter is going to be going through today.

While Finch and the guy from the blue team approach their sisters' **** lower halves, the announcer calls Thomas and the first guy from the blue team over to one side.

"Can I have quiet please! Are you ready for your first question, boys? Here we go. We asked both of your sisters to rate the statement... 'I masturbate at least once per week?'"

Both boys look away with disdain. While they think about it, the two girls begin to receive their second fillings of the day, courtesy of their other brothers.

It only takes a few more moments before both guys give the same answer.

"True."

"That's correct! An easy one to start with. Here you go! Green team, you get red bonus condoms, and blue team, you get purple bonus condoms."

He throws a colored condom at each of them.

"Enjoy!" He teases.

You can't help but frown. But in one sense he's right - this task will be even less enjoyable if you run out of condoms. Nobody here wants to fill their sister, niece or in your case, daughter, with their semen.
