It pushes into your mouth.

The warm tentacle tastes like a sweet cock. It thrusts back and forth with small motions, making you salivate and coat it with your saliva as it violates your mouth. A sugary fluid leaks from its tip and you can't help but suckle on it, doing your best to swallow as you dangle upside down. Then you feel more tentacles wrapping around your body, their damp, slick surfaces cool and sticky against your skin, hot with panic. They hold you tightly, as if you're in the grip of a huge fist, and then you feel one worming its way under the waistband of your panties. You can feel its warmth sliding over your wetting folds, and it keeps going, pushing between your buttocks and out the other side of your underwear. Its constant slithering feels like it's continuously grinding against you, until it suddenly halts. The tentacle pulls upwards, tearing off your panties, and leaving your whole body exposed.
