Sleeped with a sleeping girlfriend's brother

Two friends recovered after yesterday's drinking party, and it so happened that one of the girlfriends is a fierce nymph. She woke up from a hard drying and went to the kitchen to drink water, and met her friend's brother there. He just looked at her ass, as a girl instantly flew a spark in the brain, and she dragged her brother into the bed where the sister of this young man slept. Trying not to break the silence, she first sucked his cock delightfully, and then, trying not to wake the girl sleeping nearby, the couple began to fuck lively. The bed was shaking as abnormal, and sometimes the girl could not restrain the moans, but thanks to some miracle, her sister slept like a murdered one.
