After college sex and the neighbor trying to impregnate me

It started when i saw him at the bus stop near the community college and offered him a ride home. we made an arrangement that i would pick him up on my way home from work. our chats became sex related and about his gf and advise. eventually, i masturbated for him in a teaching moment and it grew to me giving him blow jobs on our patio and then frequent screws in the late afternoon
