Your body made its way to your bedroom and lay on your bed. "Once tomorrow is here, I'll let you back in charge," it said, before it looked at its feet-hands again. "But first, I want to try something before I sleep."
Lifting the feet up closer to your face, it began to lick them like it had much earlier. A pressure started at the point where your head and body were plugged together. It was a stiffness that felt very nice but also very disconcerting, throbbing inside your fully-stuffed neck. That feeling grew stronger and more intense the longer your body sucked the toes, your tongue slipping around them as it rubbed the feet across your face. Abruptly it stopped, but then it moved the feet-hands a little lower and gripped your neck. With an upwards pull, you felt your head and body separate, the dick withdrawing most of the way out.
Blinking, you realised you had control of your head again!
But -- before you could do anything, your body lowered your head right back down onto the erection, though not quite all the way to the hilt. Your neck-vagina clenched in reflex around the dick, and you felt a strange pleasurable heat flush across your face. Then -- again -- your body was pulling your head up and the dick was moving out.
By now you had figured out what your body was doing. You wanted to resist what was happening somehow, but any attempt to stop it was interrupted by your dick plunging back in. The alien sensation of the hard shaft sliding through the well-lubricated vagina into your head was simultaneously wonderful, erotic, bizarre, and very scary. Along with the knowledge that your dick-headed body was still in control and essentially fucking your head, you vowed that nobody could ever find out what you had accidentally and foolishly done to yourself -- you HAD to fix this!
After another in-out stroke, you couldn't help but groan, swept up in the ecstatic humiliation of the moment. A couple of minutes later, after slowly pumping up and down a number of times, you felt your vagina tighten and squeeze around the dick, the climax building. It swelled inside you in response, and with a long low moan, you came at the same time. You felt the cum gushing into you, the dick releasing its load while you had your first female orgasm.
With a soft slurping sound, your feet-hands pulled your head clean off, the softening dick slipping out of you. It managed to wipe the cum from around your neck, and placed you in a safe spot in the blankets. Then the dick-headed body relaxed back, exhausted from its sexual adventure, and lay still, going to sleep. Yawning, you too begin to lose consciousness, too drained to even think about the fact that you were now a helpless decapitated head who had mistakenly gifted the rest of his body to his own dick.
That was a problem for tomorrow.
