Doesn't have to be a gay boy! I'm a married guy who loves to be inseminated by another cheating husband. I lay back, spread my thighs and raise my legs just like their wives do. Except, I'm much tighter, and they can enjoy me for the physical sensations alone, without all the mental and emotional stuff.
That feeling when his cock starts to jerk inside me and i could feel his warm sperm shooting into me...that made me forever his bitch. I was 70 when this happened...he was 26 and he was fucking me with a passion....like a wild dog....and i was loving it.
It sounds like you had a good experience with a great top. He knew how to break you in without breaking you. If everybody who has tried anal had a good top, then everybody would love to incorporate it into their sex lives. I had a friend over one night, and we decided to trade out, fucking each other. Both being virgins in every way, we took our time and made sure the bottom was comfortable and not in pain. I became a slut that night. I loved the feeling of him shuddering over me while lying on top of me. The feeling of his cock spasms and jerks with each shot of his cum. Really lying there from exhaustion and emotional drain. But I relished the feeling of his cum, puddled at the bottom of my ass pussy. It stayed there all night, as did his, even with our continued playing. I think it really joined us on a brotherhood level.
You said, "Nothing like feeling cum being pumped deep into your ass pussy. . . . "
Yes! The guy who got my ass cherry told me beforehand that I'd be naturally inseminated. Since I was virgin (and he was rather thick) it hurt when he did what had to be done. My tears weren't completely dry when I felt his penis start to jerk and twitch deep inside me. It was an incredible sensation, knowing that his sperm - the essence of his masculinity - was spilling freely deep into my guts and he'd be forever part of my body.
You said, ". . . . Then for them to keep their cock in you so that the cum can be absorbed . . . . "
He did that, too. His body was stretched out on top of mine, in missionary. He started kissing, and when he finished twitching he made some long, slow strokes so I could feel how the texture had changed inside me. Then he reminded me that I was in the traditional girl's position, and if I was a girl then his seed would be making me pregnant at that moment.
