Grace is relaxing on the sofa, looking forward to going to the spa tomorrow, when she feels a weird presence in her belly...oh my, it's the Alien again! It starts moving up and down in her belly and Grace feels the urge to rub her navel as if it was her clit, becase it gives horny sensations... and the Alien seems to appreciate, making her belly go up and down and stronger and stronger..

Grace is in ecstasy!
