communist porridge
Pressing the penis' tip firmly to your girlfriend's anus hole, unbeknownst to her while she's sleeping; slowly milking out a hot load of semen and ejaculating the whole shot directly into her butt without waking her up.
After me and Wendy had had a few drinks and some sex, she decided to stay the night over, so while she was sleeping I cuddled up tightly to her backdoor and fed her some communist porridge.
