Helen's eyes widen in disbelief as she realizes she's cumming, her body shaking with unexpected pleasure. Bollocks, her partner, grins wickedly, knowing he's hit the spot. He continues to pummel her, his big cock stretching her tight pussy. Helen's squirts spray, drenching them both, her cum mixing with Bollocks' pre-cum. The sight of their combined fluids sends Helen into another orgasm, her body convulsing violently. Bollocks, unable to hold back, pulls out, his cock pulsing as he covers Helen's body in his hot, sticky cum, marking her as his.
