Struggle wildly!

You struggle furiously against the vines holding you against the tree. This seems to provoke the vines to bind you even more tightly. Several more vines wrap around your arms and chest, pinning your arms to your sides and pushing your back against the tree. You feel a vine creep around your other ankle and draw it tightly behind you. You look down to see a few smaller vines poking at your loincloth before creeping under it to wrap around your rapidly stiffening cock. You pull again at the vines binding you but are unable to free your arms at all.

The vines around your cock begin to pulse and become slippery - some sort of sap perhaps? - and you feel yourself drawing closer to orgasm. You buck your hips involuntarily as the vines continue to tease and stimulate your cock to a full erection. The loincloth begins to feel tight around your cock, trapped inside it yet completely **** to the invading vines...

Unable to contain yourself any longer, you arch your back and thrust your hips forwards as the vines squeeze and stroke you to an intense orgasm. You shoot again and again into your loincloth, before your vision dims, a sensation of falling takes over and you lose consciousness...
