Nikolai B

You and Nikolai are siblings (or brother and sister if your character is female), you've always loved spending time together and still do, despite your brother's busy schedule.
Today you decided to go for a swim somewhere, because you wanted to relax your muscles and you went to Lake Ladyzhensky, because it was closer to St. Petersburg.
You quickly changed your clothes and you saw how your brother quickly took off his towel and T-shirt on the run, remaining only in his swimming trunks, and then his slippers, after which he jumped into the lake.
