In a certain residential area of Katsushika Ward, at 8 PM. I passed by a petite but well-proportioned big-breasted woman (estimated 153cm, G-cup). I reflexively followed her. The woman who entered a certain apartment building and opened the auto-lock with a key went to the room without even checking behind her, so I quietly followed her and checked the room... I immediately moved to the balcony. In the room, a man is lying down while playing with his cell phone. As soon as the woman returns home, she changes into her underwear and heads to the bed where the man is waiting. The two devour each other's tongues and lips. The man takes off her bra. They are indeed huge breasts, and they are bell-shaped, and the areola and nipples are also beautiful... The man buries his face and enjoys the huge breasts with all his might. I'm envious... Then cunnilingus. The woman trembles her body in twitches in response to the man's tongue movements and feels pleasure. She seems to have good sensitivity. When the man takes off his T-shirt, the woman begins to lick his nipples herself. She's horny. As expected, a woman with an erotic body is erotic... Then the woman takes his dick in her mouth as if cherishing it. Oral sex is also erotic. She is savoring it with her whole mouth as if tasting it... Lying the woman on her back, another missionary position after cunnilingus. While interweaving kisses, the woman puts her legs on the man's waist. The two must really love each other. And then cowgirl position. The woman moves her hips while making an erotic face. From grinding cowgirl position to covering kiss cowgirl position. The distorted face that occasionally shows pleasure tells of her pleasure. Next, from doggy style shaking her huge breasts, then missionary position ~ cowgirl position ~ finally missionary position finish. Even after cumming, the two continue to cuddle. Real couple's real sex. I thought this was the most erotic in the end.
