I always like doggy but I have grown fond of on the sofa legs pushed right back, and with my feet firmly on the ground for support and also have the choice of pussy or asshole fucking
Doggy will always be favourite getting a great arse up in the air and mounting her and fucking pussy and arse, and then dismounting her and going to the front and letting her see the length she is getting
Missionary with her legs entwined with mine where I can watch her expressions as I move inside her vagina. It's better if she has an orgasm or two before intercourse so she may be sensitive to my thrusting and be able to reach another orgasm. From this position I can enjoy the rise and fall of her breasts and sample her nipples, explore her face, neck, and shoulders, hold her in my arms tightly chest to chest, or lock onto her lips with mine and kiss her deeply. We can also tell each other what it is that makes this feel so good. No other position allows the full frontal contact and control that I like or the depth when I ejaculate.
Missionary. it is the most comfortable for her, and I have access to her breasts, which need lots of attention to keep her happy.
Me on top of her. She's on her back with her legs over my shoulders, just about folded in half and her pussy is taking a good pounding from my cock.
I'm on my knees, she's on her back with legs in the air spread wide apart. I can see everything and touch her anywhere. I stroke her clit while fucking her. We've had some insane orgasms like that. Or if we're going for intimacy missionary so I can look in her eyes and whisper in her ear.
