"Chris...?"

You felt the mystery girl stiffen momentarily, pausing her kisses as she gasped suddenly.

"... Yeah...?" Chris replied sheepishly after a pregnant pause. Nebula wolfwhistled as Chris started jacking you faster, squeezing your scrotum tighter. Chris stood up shakily, mounting your lap and letting your hardening cock rest against her thigh. Chris stroked your cheek lovingly with her palm as your dick rested snugly against Chris' groin.

"You're amazing..." You muttered blissfully. You felt Chris shudder, burying her face into your nape to hide her joy. Chris wrapped her arms around you tightly, hugging your back. You returned Chris' embrace as best as you could, considering your wrists were bound together.

"... Sam... I... I lov- I- Um..." Chris stammered, before grunting angrily. "God, why is this so hard? Look Sam... I... I lo-"

You interrupted Chris unintentionally by your dick slipping upwards between Chris' labia. Chris squeaked girlishly as the shaft of your cock wedged in between her folds. Chris, realizing she was running out of time, started bouncing frantically, grinding your rod against her womanhood as Nebula counted down from ten. Nebula was drowned out as blood rushed to your ear drums and your heartbeat echoed deafeningly. You and Chris locked lips, tongues intertwining and saliva mixing as Chris rode your penis close to penetrating Chris' slit. You felt Chris start leaking fluids down your shaft as she rocked against you, her thighs creating a **** grip on your cock as you let out a volcano of cum between Chris' thighs. Nebula cheered as your seed shot upwards, painting Chris' back and ass alabaster white as she hugged you during your orgasm.

"Time!" Nebula yelled, followed by heavy, fast pattering towards you and Chris. "Looks like the score is tied! Now its time for Round Two..."
