Prompt - IndigoSP: I loved your rendition of Spock’s retractable penis in your last Spirk drawing, I’d love to see Jim being really into coaxing Spock out  into hardness. Maybe AOS this time but I love both so don’t mind TOS again either!

They play a game, after they learn each other's bodies; Spock becomes loose enough to penetrate, if it's done before he everts, and Spock finds a particular illicit pleasure in giving himself to Jim this way. But Jim likes to receive just as much as he likes to give, so he won't hold back on his preparations, and Spock is embarrassed to admit he can't always prevent the eversion when he'd like to, though pushing into Jim's body is its own kind of primal pleasure. Still... the score has been a little too even between them lately, and Spock would prefer to win...

I'm sorry I picked TOS again, I'm addicted ;o; 

I'm using the "fantasy intersex" tag for Spock's genitalia, since there's kind of a male/female impression going on; if there's a better tag I should use please let me know~

Content warnings: alien genitalia, fantasy intersex sort of, everting cock, f/ingering
