Older sister teaches younger brother about sex

A brother and sister were doing their homework, and at some point, the guy saw that the girl had spread her legs and was caressing herself through her panties. He became aroused and could no longer think about anything but her wet pussy. Then she pulled aside the edge of her panties and began to caress her pussy more intensely. Then she took her brother's hand and showed him how to make her feel good. Next, the girl saw that the guy's cock had become big and hard and decided to reward him with a hot blowjob. After that, she climbed on top of him, turned her back, and sat on his cock. After fucking well, the girl wanted her brother to cum inside her.
