You’re trying to make Lena cum, but Lauren makes the edge even more intense, shocking you a bit, swallowing few drops of serum.
LENA: Lauren, i'm getting close, his tongue is devilish, i don't know how long can hold back.
LAUREN: Neock, if you make her cum, the only result is that we should restart the treatment completely.
Lauren suggests to Lena to use her hand, so she starts rubbing your crotch and perineum with her fingertips. You moan, overwhelmed of stimulation, freeing Lena's nipple barely before she cum and a flow of serum fill your mouth.
