In the dimly lit living room, the siblings find themselves alone, a new dildo lying on the coffee table. The boy, always the explorer, suggests they try it out together. The girl, intrigued, agrees. She lies back, spreading her legs as he teases her clit with the toy before slipping it inside her. As she writhes in pleasure, he can't help but free his own cock, stroking it in time with her movements. Their moans fill the room as they chase their release, the double penetration pushing them both to their limits.
