Hairy surprise for a skinny but very harmful sister

It's my sister's birthday today, it's time to give her a little surprise. Knowing how difficult it is to please this picky bitch, the brother decides to take extreme measures. Blindfolding her, he places it in his friend's hand. Miss didn’t expect such a turn at all, and therefore for a moment she stands with her mouth open in surprise, but then she realizes that she won’t be able to cope with this situation without a blowjob. The satisfied brother was completely delighted with how well everything was turning out, but he also did not remain in debt, returning the favor with mutual cunnilingus. After this, control over the situation was completely lost; the dinner table had never seen such debauchery.
