[PMC-323] Forcing Brother to Creampie for Pregnancy - The Secret Formula of Cock Insertion (Chinese AV)

To get pregnant, the sister actively climbs onto her brother's bed, begging for an internal creampie of thick semen! She grabs her brother's swollen cock and shoves it into her hungry pussy, twisting her waist and hips wildly while riding him, moaning, 'Brother, cum inside me and get me pregnant with a baby.' The brother, overcome with temptation, thrusts hard, his cock slamming deep into the uterus, and the sister's vagina spasms, sucking up every drop of semen. The secret formula for conception is the brother's hot cum poured directly in; as the sister reaches climax, her breasts shake wildly, and her juices mixed with semen drip down her thighs. This sibling pair engages in creampie sex all night, the sister's belly swells full of her brother's seed, and their taboo pregnancy plan is a huge success!
