My Dorm 144 - The Topless Pool (Birthday) Party Part 11 - Betty masturbating by seeing Mark and Alexia's Sex in the Hot-Tub

As Betty enters the hot tub, she can't help but feel excited by the sight of Mark and Alexia's naked bodies entwined. She takes a seat on the ledge, her knees parted, and lets out a soft moan as she watches them. Her fingers slowly move up her inner thighs before sliding under her bikini bottoms and beginning to tease her bare pussy. She starts rubbing herself gently, her hips grinding against the edge of the hot tub in rhythm with her movements.Eager to please her, Mark notices Betty's actions and shifts his hips towards her, his erect cock brushing against her stomach. She gasps at the sensation and leans forward, allowing her breasts to fall into the water. Her nipples are already hard and poking through her bikini top. Alexia, sensing the unspoken appreciation in Alex's eyes, feels a wave of arousal wash over her as she wiggles her perfectly rounded ass, inviting him to take a closer look.
