Me and my friends are going to a party so I went showering. When I leave the shower I don't see my friends so I assume they left without me. I sit on my bed and I feel something weird on my butt, it seems something is bitting me. I begin to shake my butt and bounce my butt again and again to scratch my butt and it seems to work. I get up and twerk my butt but the "bites" don't stop. All these bites starts feeling nice and I get horny. I start masturbating and fingering my pussy. I take a dildo and start fucking myself until I cum.
