A door closing

Haley froze thinking she was caught when she heard a door close. She began scrambling to pull the blanket back around herself when she realized it was the back door that closed.
"Awe, Manny," came the thick Latina accent from the backyard. It was Gloria. Haley still couldn't see her, but she could hear her fine. "You started without me."
Haley's eyes went wide as she went over what she just heard. Manny started without her? What?
Haley grabbed her phone knowing whatever happened next she needed to record it. She hit record and began rubbing her clit again.
"I was just getting ready," said Manny in his boyish voice. "Besides, you know I could never finish without you."
"Oh Manny, you are so sweet. You always know what to say," called Gloria just now coming into Haley's view and what a view Haley had.
Gloria, the embodiment of a milf, was wearing a see-through black cover up over her bathing suit.
"What do you think?" Asked Gloria as she stepped in front on Manny dropping the cover up to the ground exposing the treasures hidden beneath.
Gloria was wearing a black one piece suit. The suit barely covered her gigantic breasts. It was low-cut and backless exposing her soft skin to the world, but more importantly was the bottom half. It was a tight thong wedged between her ass cheeks. The combined sight of her grandmother's amazing ass and her cousin's huge dick pushed Haley over the edge. She began to orgasm the moment Gloria's ass was exposed. She felt the waves roll over her as she buried her fingers as deep as they could go into her pussy. The orgasm shook through her tiny body. Haley's back arched as she thrust her hips forward trying to get her fingers as deep as possible. She threw her head back trying to be quiet, but her head bumped against the fence with a thump. Haley froze. How could she be so stupid? They must have heard her.
