My younger sister has started a popular "beauty butt training" and I have to go along with her! I get a panty shot by lifting up my legs! I can see the shape of her pussy in her tight spats! I can't stop getting a full erection, and my sister shows me her thong ass to push me over the edge! She pulls down her pants and immediately inserts herself into me! However..! The training has made her pussy so tight that she immediately climaxes and cum inside me! She was so excited that she started to swing her hips around in a four-way piston cowgirl position! She was forced to continuously cum inside her without pulling out until her pussy was overflowing with sperm!
