In the dim light of their shared room, a brother and sister, both 23, can't help but let their eyes wander over each other's bodies as they lie in their beds. The sister, a petite brunette, has been tossing and turning, her mind racing with taboo thoughts. Her brother, tall and muscular, has been trying to sleep, but his cock twitches at the sight of her curves under her thin nightgown. When she reaches down to stroke herself, he can't help but join her, his hand moving under the covers to grip his hard cock. Their eyes meet, and the tension between them is palpable. They're both torn between their desires and the knowledge that they shouldn't be feeling this way about each other.
