Feeling Sabrina clench around him, Ken kept thrusting as best he could as his girlfriend's pussy became even tighter. About to come himself, he missed his mark on the last thrust, his cock sliding up along the two pussies. Coming with a groan, his cock spurted his seed up and over Luna. Closing her eyes against the torrent, Luna had her sister's boyfriend's come splattered over her stomach, breasts, and face.
"What was in the potion?" Luna asked, suddenly curious.
Appearing bashful, Ken sat back to let the two sisters get up. Sliding off Sabrina, Luna laid down next to her. Wiping the come off one eyelid, she peered at her sister and grinned.
