Her sleeping sister lets her fuck her so she empties her eggs

Waking up with his brother's cock in his mouth has been a shock, but it does not seem that this girl has been as angry as most would have done. The aunt waits for her brother to give her some explanation and tells her that she needs a favor to empty her eggs, because she hasn't run months since she left her girlfriend and they hurt a lot. He is a firm uncle in terms of not making straws, so his sister is all he has left to stay at ease and release a good run. Luckily for him, the sister says yes, but they have to do it quickly and quietly, so he sucks a little and opens her pussy so he starts drilling her.
