Becky wants to play with you and Kim

By: Cheese111

Kim yelled up to your girlfriend, a pang of concern in her voice. "Becky! Are you okay?!" She didn't get an answer straight away, but the look in Becky's eyes when she noticed your sister was enough to make anyone worry. A large hand came down and soon she too was wrapped up in a firm grip and brought to Becky's face.

"Haha, you're so puny now, just like little Willy. I bet you're loving this as much as he is." The titanic woman let out a big laugh.

Kim blushed, not answering directly. "Are you feeling alright? No strange sensations after that much growth? I think this is probably the peak of what my chemistry can accomplish for you, but I bet that's more than enough." She was making educated guesses based on her knowledge of these things, but in truth she hadn't expected even half as powerful a result to happen. This was unknown territory for her.

Becky on the other hand was right in her element. "I'm feeling better than ever. Now I have two new little toys to play with."

You expected your sister to be shocked or horrified, but she was seemingly unfazed by this revelation. Your girlfriend just announced that she was no more than a plaything to her, but Kim just didn't seem to mind. Or was she trying to hide something worse. Was she... into this? After all the nightmares you endured yesterday you were positive she'd only love the part where she got to play with tiny people. Now that the roles are reversed... she is looking... excited? You shudder as Becky's gaze falls on you once more. Her grip tightened, making you groan and dribble more cum onto her hand. If that mess upset her, she was doing a great job of hiding it.

Becky's smile got even bigger and more devilish as she felt a very distinct sensation. "Oh, you're excited, aren't you?" She seemed to direct it at both of you, but you knew she was talking about your sister. Did Kim really get hard from all this? Becky had no need to guess, feeling the distinct touch of a rock-hard boner prodding the palm of her hand. "Well, I know just what to do about that." The titanic woman cooed. Her hand unfurled around you, forming an uneven platform for you to lie on. You stayed down on your still aching belly, not daring to stand up in case you lost your footing and fell off. Suddenly a shadow loomed over head and Kim was dropped on top of you.

"Oof... thanks babe." She said, her voice dripping with lust. You weren't sure what was about to happen when you felt her arm slip around your neck and a warm mass prod against your ass. Is she for real? After fucking you not five minutes ago? Kim's libido took charge and after a few attempts she drove her cock up your ass once more. In the past taking a foot long cock like that would've hurt a lot, but after so many intrusions from Kim and Becky it loosened you up in ways you didn't think possible. You gasp in shock as she goes to work in plain view of Becky, who just giggled and smiled.

"You two look so cute. I love seeing my toys get along so well. But I bet I can make this even more exciting." She cooed gently. She might enjoy this, but you knew that things were about to get much worse.
