First is making out with tongue. If done properly, there should be no slobber on the female's face afterwards.

Second base is when a guy feels up a female's breast over clothing, under clothing, or under the bra.

Getting to third with a lady is fingering, and hitting her G spot- the bone or hard wall at the top of the inside the vagina where she is most sensitive.

Fourth or hitting home is when the guy penetrates her vagina with his member, and has sex.

Note: Third and fourth is usually done in one "run," though that run may require patience and a deeper emotional connection.
Lily (from How I Met Your Mother): *comes in with handprint on the breast area of her shirt. "It was finger-painting day at school and a 5-year-old boy got to second base with me."

In the standard system of baseball/sexual metaphor (see first base, second base, home run), fondling the breasts and/or buttocks of one's partner.
I would have reached second base if his parents hadn't walked in.

highly debated base when talking about sexual accomplishments, all that needs to be done is to clarify what "league" youre "playing" in.

second base in minor league baseball is feeling a girl up.

second base in *major* league baseball is fingering or handjob.

Major league- 1st base makeout with feeling up; 2nd handjob/fingering; 3rd blowjob/ eating out; home sex

minors- 1st base makeout; 2nd feeling up (breasts); 3rd oral/fingering/handjob; home sex

"oh my god becky, last night, james and i went to second base!"
"major or minor league?"
"major baby!"
"oh wowww"

1) The second of four bases (including home plate) in the game of baseball.
2) Many argue the status of this base in terms of sexual engagement. Some believe it is intense feeling, while others believe it is a handjob/ fingering. Take your pick.
1) Johnson reached second after pounding a double up the middle. He gave a two finger salute to the crowd, acknowledging his 300th hit.
2) Johnson reached second with his two finger salute pounding up the middle.
