The sticker finally bursts as Kim walks in

Original Author: Poopoodoop

Alice's dick needed to release its pent up fluids, and the only way out was by pushing through the sticker on her slit. Her cock had swelled up so much that the narrow chamber you were trapped in felt immensely tight. Alice was screaming and moaning so much that it brought her to Kim's attention. Your older sister walked to the room, only to freeze in the doorway. She had walked in on Alice fapping before, but her dick and balls were never this large.

"Alice, is something wrong?" Kim asked. She was generally concerned, and didn't notice the slight bulge along the front of Alice's cock.

"Ooh! So goo- AH!? Kim!?" Alice screamed. The mix of arousal and surprise caused Alice to clench extra hard, smashing you between her urethra walls.

*SQUELCH*

"Aaahhhh!" Alice had released the biggest load in her life, rivaling even Kim's volume. Each jet lasted several seconds, and she sat there cumming for over a minute. When her climax was finally over, she opened her eyes to quite the sight. Her older sister absolutely drenched in her cum, along with the floor and basically everything she owned in that direction. Kim simply stood there, her erection growing by the second.

After a sensation like that, Alice forgot that you were in her dick, and that you were propelled onto your sister along with the biggest cum shot you'd ever seen. You were stuck in a pool of cum between your older sister's cleavage. It was so thick that it was hard to stay above the jizz. The level of Alice's cum suddenly started to lower. You looked down to see the foreskin covered tip of Kim's huge dick. It pierced the very bottom of her cleavage, allowing the thick white goop to escape. As you descended towards Kim's cock your foot got stuck under the edge of her foreskin.

Kim felt your intrusion, but she just assumed it was a clump of cum. She stuck her finger in her foreskin and dragged it around her tip, pushing you in. She brought her finger to her face to inspect what it was, but all she saw was a small clump of smegma. With that sensation gone, Kim approached Alice. She was still laying on her bed, breathing heavily from her previous session. Kim began stripping in front of her sister, who was too tired to notice. She repositioned Alice so that her head was hanging off the edge of the bed.

*pant* "H-hey sis what's the bi-GLMPH!" Alice's question was silenced by Kim's massive ball sack enveloping her entire face. Kim gyrated her hips, dragging her sack in a circular pattern on Alice's face.

Alice tried pulling away but Kim wrapped her legs around her head, holding her against her balls. "You've had your fun, now I'm having mine!" Kim laughed.

After a little more time smothering her sister with her nuts, Kim finally moved. Alice's face was drenched in ball sweat, and it reeked of Kim's musky sack.

Kim grabbed her head and lined up her massive schlong with her lips. She gently touched it with her tip then pulled back, a string of precum trailing from her slit. "Any last words before I ram my third leg down to your stomach?" Kim asked, already sticking the tip of her dick in Alice's mouth.
