My father’s wife is an extremely strict woman, and I’ve known her for at least 10 years. This close relationship has basically made her my mother. I usually have problems with cleanliness, and that’s why she asks me to tidy up everything because her sister is coming to the house. To irritate her when her sister arrives, I go downstairs almost naked to greet her. It’s then that I can see that my step-sister, who I’ve been anticipating, is a mature, beautiful woman with large breasts who really turns me on. I calmly go to take a shower, and that’s when I feel her get in the shower entirely naked to start jerking me off. Seeing her like that makes my dick stand up really hard, and she doesn’t hesitate for a second to give me a delicious, long blowjob. When I can’t take it anymore, I make her face away and start fucking her pussy with my hard dick. The bitch starts feeling pain and that only turns me on more by hearing her yell very loudly. We keep fucking, but we change positions, now she’s on top of my dick and she doesn’t stop riding me up and down really hard without stopping to scream in pleasure.
