"Ooooggghh...." you moan, focusing on the feeling of your cock wrapped in the fox's sheath. He simply grunts in response between licks, continuing his ministrations while your chest becomes more and more sensitive. Excitement builds up inside you, seemingly inflating your hardening nipples, imploring you to thrust your hips harder and harder.
"Ohhh... y-yahh..." escapes your lips as your breathing becomes more excited. You notice aslightly feminine twinge emerging in your voice, but can't focus on it. This only causes the fox to redouble his efforts, bringing his padded hands up to squeeze and massage your pecs while licking ever more feverishly. Your hips are on autopilot, gyrating in a lusty rhythm, pushing your hot head against his over and over, but something feels off. You keep going, but his cock head just grows harder and hotter while yours softens. This continues on for a few more thrusts until you feel your softened cock pop out of his sheath.
You look down suddenly in shock and let out a gasp as you see it all. You can see the fox man greedily pulling at your swollen, hardened nipples. They're huge... easily three times your normal size... but a glimpse of the void at your crotch is what causes you to whimper. He's pushed you out of his sheath, and now his hard red member is poking out, bobbing up and down with mascline power. The loss of your manhood shocks you, but your excitement is even higher, and your hips are still going...
Instinctually, you grind what's left of your penis head against his. Again and again you gyrate against it, pressing a warm, needful spot against his hard cockhead. You don't even stop to think about your missing balls as you feel something begin to catch against his hot member with each movement. You both thrust just a couple more times and... it catches.
With sudden realization, a whimper escapes your lips: "Ogh... no..."
But you don't stop. Without a word, you reposition yourself and begin to press your hips purposefully downwards.
"Ohhhhhhh, I... I..." you continue, feeling nothing but a feeling of warm fuzziness as his head press deeper into the soft skin in your groin, "Noooooghhh I..."
But what little resistance you felt was all for naught. With a final overwhelming wave of lust, you pull back a bit a push back down once more. Your body needs his cock inside of it, and it keeps working as hard as it can to make it happen. The heat in your groin grows significantly, and with a sudden "pop" you feel him enter you. Before a thought can form in your mind you push down again, slowly, methodically, and slide him deeper into you. "Yeah!" you cry softly, eyebrows furrowed in determination, and you gyrate once again, sliding down further this time. His hard head is now fully inside you, and your body needs the rest.
