Sphincter Shake

The sexual act in which one partner lays on the ground face first and proceeds to stretch their butt-cheeks apart revealing the anal cavity. Their counterpart must be a lactating woman; she squeezes her breasts into the anus, causing the nutritious milk to pour inside. The milk mixes with remaining fecal matter creating a delicious snack. She then kneels down and felches the milky shake out of the anus.

After hours of exhausting fornication, Jennifer decided she could go for a sphincter shake fresh from her lover's anus. Hopefully she doesn't wake the baby.

sphincter shy

Not being able to take a shit in front of other people. Similar to being bladder shy, only with taking a shit.

I needed to shit so bad while we were on the beach, but due to the presence of other people on the beach, I became sphincter shy.
