napa valley conception 

A method of conception where by one lesbian performs fellatio on a man, swishes his load around in her mouth, and spits it into her partner's vagina in hopes of causing a pregnancy.

Those two dykes wanted to have a baby, so I met them at the Holiday Inn for a napa valley conception.

concertina

a small musical instrument, typically polygonal in form, played by stretching and squeezing between the hands, to work a central bellows that blows air over reeds, each note being sounded by a button.

I play the concertina.

Conception Balm 

Obviously semen but more specifically semen used as a lubricant after the performance of a creampie. In most cases, the person providing the semen will be the conception balm user at the time of second sexual encounter. If someone else is using your conception balm, it is simply sloppy seconds.

The second time is the best, especially when I leave behind some conception balm.
