Kayla is a spy, her body augmented for espionage. Her tits have been enhanced to store oxygen, as her next few missions risk underwater submersion. She begins by narrating her missions, before we watch her in action.

Mission 1:

Kayla runs and ducks behind a couch. She fires off a few rounds, getting h*t twice in the tits and once in the stomach. She falls back behind the couch and removes her tank top. "Cover your mouth with this so you don't have to breathe in the water. My tits have enough air left in them to last for awhile. I won't run out til you escape." She winks at you, touches her breast, then rises for action. She gets h*t in both tits, recoiling and groaning with pleasure. One more h*t and she's down again. "Ahh. Told you they really love to fill these with lead." She rubs her breasts. "I still have some more air left. I'm not going down yet." She seems to be getting slightly aroused, rubbing her p*ssy lightly. She jumps back up, eager to fight. She is h*t again in the stomach and breast while yelling "Come on, fill these tits with lead!" She's h*t again and is downed. Her hands go to her throat, as she coughs in the water. She struggles to breathe and manages to tell you "I won't last much longer. I'm going to swim to buy you more time." All the while she is growing more and more aroused, playing with her tits and p*ssy. She drags herself back up and makes a break for it, aiming at the enemies along the way. She's struck 3 more times. "They're riddling my body with lead!" And her hand is on her throat as she attempts to stop the inhalation of water. "Come on!" She goads them. One penultimate h*t "I'm done for...get out of here." as she reaches for her p*ssy, but finally, she is taken down. She groans orgasmically, winking at you, before falling down.

Mission 2:

She is aiming at some enemies, making her way through the underwater tunnel. Her chest is wet. She looks towards you as she picks up the device, a cellphone. "I've reached the tunnel, it's too long. If I don't go down before I get to the end, I'll certainly go down on the way back." She looks down at her tits, and plays with them, before moving ahead. She is h*t in the breast and clutches it with her hand, while continuing to aim with the other. "Come on you bastards, h*t me in the tits!" She is struck in the other breast, and then the p*ssy. She brushes it off and keeps moving. Her body was designed to take it, but she is weakening from lack of oxygen. She is h*t in the *ss, and covers her mouth as she is running low on air. She tinkers with the phone, attempting to hack the server and stop the detonator, her cheeks are puffed. She starts to make her exit, heading back, but is h*t again in each tit. She makes it to the exit but it's locked. "No. The entrance is shut!? You betrayed me??" She's h*t in the stomach and accidentally gulps down some water. "No! My lungs and tits are filling with water!" She moves weakly and is h*t a couple more times and she grasps her throat with both hands. She falls to the ground writhing "I can see myself in third person. My massive breasts bounce a few more times as they fill with water. I finally go..." And she lays still.

Mission 3:

Kayla is sneaking, arms at the ready. "Hmm. Submerged again. I'll need to use a filter of some kind or I'll surely inhale too much water." She kneels and removes her tank top. She places it over her mouth as she tinkers with an invisible device, attempting to hack in to the system. She coughs and drops the tank top. "F*ck! I'll have to hold my breath manually. Let's hope my big tits and I don't go down before completing the mission." She puffs out her cheeks and gets back to hacking. But she must have triggered the alarm, she stands and gets ready to fight. She is h*t in the breasts twice but continues to hold her breath, cheeks puffed. She returns the h*ts but gets sh*t in the *ss. She ducks back behind the couch. "F*ck. Two minutes until the device is finished uploading, but I'm running out of air." She gets back up, and is h*t in the breasts and stomach some more. "My body is being filled with lead!" She remains standing but is clearly growing weaker from the lack of oxygen. "F*ck, I'm almost out of air...just 30 more seconds..." She continues to get h*t, as her free hand alternates between holding her throat and pinching her nipples, while she continues to aim with the other. One more sh*t to the breast and she falls to her knees. Both hands grab her throat as she tries to stop the water from filling her breasts and body. One hand leaves her throat and gropes her breasts and p*ssy, she is clearly turned on by this. "No...I failed." She is h*t a final time, in the throat, and drops down.
