Summer Vixen wants to test her friend Nathalia's cute and tight little tummy to see if she has the quiver factor. Summer lays at Nathalia's exposed belly and starts to lightly run her fingers and nails over Nathalia's belly making it quiver. The more Summer uses light touches on Nathalia's stomach the more it quivers and Summer likes finding new spots. Nathalia's belly reacts so much to Summer's touch as Summer explores, finding out Nathalia definitely has the quiver factor.
